Scientists believe they have discovered the reason why stress can make hair turn white. They’ve also found a potential way of preventing it from happening which doesn’t involve hair dye. In a chance finding while studying mice, the scientists noticed that dark-furred mice turned completely white within weeks after experiencing stress. The reason for this, the scientists say, is because the stress damaged stem cells that control hair and skin colour. The US and Brazilian researchers say their discovery is significant as it could lead to new treatments being developed that can protect hair colour from the effects of stress and ageing. Publishing their findings in the journal Nature, the researchers Universities of Sao Paulo and Harvard say the effects are linked to melanocyte stem cells, which produce melanin and are responsible for hair and skin colour. In a separate experiment, the researchers found they could prevent stress from affecting hair colour by giving the mice an anti-hypertensive, which treats high blood pressure. They were also able to identify the specific protein that causes damage to the stem cells. When this protein, cyclin-dependent kinase (CDK), was suppressed, mice that were subjected to stress did not experience the same fur colour change. It’s a breakthrough that could lead to drugs being developed which suppress CDK and delay the onset of grey/white hair.
While it’s not possible or practical for everyone, training for and completing a marathon significantly improves the health of a new runner’s arteries, a study suggests. For the study, researchers from Barts and University College London analysed 138 novice runners attempting the London Marathon. Following six months of training, the runners’ arteries were seen to regain some youthful elasticity, something which should reduce the risk of heart attacks and strokes. Furthermore, the runners’ blood pressure fell by as much as if they had been prescribed medication. Interestingly, those who were the least fit before the training appeared to afford the most health benefits. The best news is that the British Heart Foundation (BHF), which funded the study, says smaller amounts of aerobic exercise are likely to have a similar effect, meaning people don’t necessarily need to train for a marathon to benefit. Speaking about the findings of the study, Prof Metin Avkiran, an Associate Medical Director at the BHF, said: “The benefits of exercise are undeniable. Keeping active reduces your risk of having a heart attack or stroke and cuts your chances of an early death.” According to NHS England guidelines, every week, adults should do a minimum of either: 150 minutes moderate-intensity exercise, such as brisk walking, doubles tennis or cycling 75 minutes vigorous exercise, such as running, football or rugby It’s also important to do strengthening activities - such as push-ups, sit-ups or lifting and carrying - at least twice a week.
People who take daily blood pressure medication should take it just before bedtime to get the most out of it, researchers say. Writing in the European Heart Journal, the researchers say that while it may sound like a very simple tip, it’s one that could save lives. The reason why taking such medication at bedtime is more beneficial is because our body clocks alter the way our bodies respond to it. At night, our blood pressure is typically lower than it is during the day. However, if for some reason our blood pressure does not dip and remains consistently high, our chances of having a stroke or heart attack significantly increase. The study found that patients who took their daily blood pressure medication before bedtime had significantly lower average blood pressure both at night and during the day than those who took their medication in the morning. Their blood pressure also dipped more at night. Lead researcher Prof Ramon Hermida, from the University of Vigo in Spain, said doctors should consider recommending their patients take their daily blood pressure medication at night going forward – especially as it’s “totally cost-free. It might save a lot of lives. “Current guidelines on the treatment of hypertension do not recommend any preferred treatment time. Morning ingestion has been the most common recommendation by physicians based on the misleading goal of reducing morning blood pressure levels. “The results of this study show that patients who routinely take their anti-hypertensive medication at bedtime, as opposed to when they wake up, have better-controlled blood pressure and, most importantly, a significantly decreased risk of death or illness from heart and blood vessel problems.” The next step is to determine whether the findings of the study apply to different brands of blood pressure medication. Lifestyle factors that have an impact on blood pressure: Smoking Drinking too much alcohol Being overweight Not doing enough exercise Eating too much salt
Gum disease is linked to an increased risk of hypertension, a new study has found. Furthermore, the more sever the gum disease, the greater a person’s risk of high blood pressure. The research by University College London's Eastman Dental Institute – the findings of which appear in the journal Cardiovascular Research – shows people with periodontitis (an advanced form of gum disease) have a higher risk of hypertension. Hypertension, according to the Centers for Disease Control and Prevention (CDC), affects 32% of all American adults, and as many as 47.2% of people aged over 30 have some form of gum disease, which is why the new research is so intriguing. While the two conditions may appear to be completely unrelated, the new research shows otherwise. And when you consider that high blood pressure is the leading cause of premature death worldwide, affecting up to 45% of adults, the findings of the study could result in much more attention being paid to combatting gum disease going forward. Specifically, the research revealed an association between moderate-to-severe periodontitis and a 22% higher risk of hypertension, Moreover, severe periodontitis was linked to a 49% higher risk of hypertension. Speaking about the findings of their research, senior author Prof. Francesco D'Aiuto, from the University College London Eastman Dental Institute in the United Kingdom, said: “Previous research suggests a connection between periodontitis and hypertension and that dental treatment might improve blood pressure, but to date, the findings are inconclusive. “Hypertension could be the driver of heart attack and stroke in patients with periodontitis,” he added.
A pill that contains four different medicines and is designed to be taken daily could dramatically reduce the number of heart attacks and strokes, a new study has found. The polypill – which is the generic term used to describe a medication that contains multiple active pharmaceutical ingredients – contains aspirin, a cholesterol-lowering statin and two drugs to reduce blood pressure. For the study, researchers from Iran and the UK studied around 6,800 people from more than 100 villages in Iran. Half were given the polypill and advice on how to improve their health through lifestyle changes and the other half were just given the lifestyle changes advice. After five years, the group taking the polypill had experienced 202 cardiovascular events, while the group that had just been given the advice had experienced 301 cardiovascular events. In other words, the group taking the polypill had experienced around a third less cardiovascular events. The researchers say the pill costs just pennies a day, but could have a huge impact, especially in poorer countries where doctors have fewer options available to them. Stroke and coronary heart disease are the top two causes of death worldwide, killing more than 15 million people each year. Obesity, smoking and doing little exercise are all risk factors associated with an unhealthy heart. Based on the findings of the study, if 35 people were all given the polypill daily, it would prevent one of them developing a major heart problem within 5 years. “Given the polypill's affordability, there is considerable potential to improve cardiovascular health and to prevent the world's leading cause of death,” said Dr Nizal Sarrafzadegan, of Isfahan University of Medical Sciences, Iran. The findings of the research are published in The Lancet.
Having high blood pressure before middle age may pose a risk to brain health in later life. According to a new study, the results of which are published in The Lancet Neurology, the “window of opportunity” to safeguard brain health runs from the mid-30s to the early-50s. And having high blood pressure in the 30s and 40s could lead to blood vessel damage and brain shrinkage. For the study, a team of researchers from UCL Queen Square Institute of Neurology followed 500 people born in 1946. Throughout the study, participants had their blood pressure measured and had brain scans. The researchers found that blood pressure increases between the ages of 36 and 43 were linked to brain shrinkage. Moreover, blood pressure increases between 43 and 53 were associated with blood vessel damage or “mini strokes” when people reach their 70s. Speaking about the findings of the research, Dr Carol Routledge, director of research at Alzheimer's Research UK, said: “High blood pressure in midlife is one of the strongest lifestyle risk factors for dementia, and one that is in our control to easily monitor and manage. “Research is already suggesting that more aggressive treatment of high blood pressure in recent years could be improving the brain health of today's older generations. “We must continue to build on this insight by detecting and managing high blood pressure even for those in early midlife.”
Most people feel nervous ahead of surgery, even if the procedure they’re about to undergo is straightforward. To calm these nerves, patients are often given medication. But a new study suggests that music could be just as effective. According to a study conducted by researchers at the University of Pennsylvania, a special song written to reduce anxiety, blood pressure and heart rate performed as well as a sedative for calming patients ahead of surgery. For the trial, 157 surgery patients were either given the drug midazolam or play the so-called “world’s most relaxing song”, Weightless by UK band Marconi Union, while they were being given an anaesthetic to numb a part of their body. Patient anxiety was equally reduced in both groups, suggesting the music was an effective alternative to the drugs. The great news about this is the music medicine is both free and completely safe, whereas the drugs cost money and can have side effects. Speaking about the findings of the research, Dr Veena Graff, assistant professor of anaesthesiology and critical care at the University Of Pennsylvania Perelman School Of Medicine, said: “Music lights up the emotional area of the brain, the reward system and the pleasure pathways. “It means patients can be in their own world, they can be comfortable and have full control.” Intrigued what the world’s most relaxing song sounds like?

A major study has found that the UK has a big obesity problem, and that there are severe health implications for people who are even just a little overweight. According to the research, which was funded by healthcare firm Novo Nordisk, individuals with a Body Mass Index (BMI) of 30-35 were 70% more likely to develop heart failure than their healthy weight peers (18.5-25 BMI). Furthermore, the study of 2.8 million adults also showed that people who were even slightly overweight were twice as likely to develop Type 2 diabetes. The study, which is due to be presented at the European Congress on Obesity (ECO) in Glasgow, also revealed: The risk of Type 2 diabetes for people with a BMI of 35-40 was almost nine times higher People with severe obesity (BMI of 40-45) were 12 times more likely to develop Type 2 diabetes People with severe obesity also had triple the risk of heart failure, high blood pressure, and dyslipidaemia (elevated levels of total or low-density lipoprotein (LDL) cholesterol levels, or low levels of high-density lipoprotein (HDL) cholesterol) A BMI of 40-45 was also linked with a 50% higher risk of dying prematurely from any cause Speaking about the findings of the study, Public Health England said “sustained action” was needed to tackle obesity.
We recently wrote about how just one rasher of bacon a day can increase bowel cancer risk. Now, new research has revealed that replacing red meat with plant protein can reduce heart disease risk. For the study, researchers from Harvard T.H. Chan School of Public Health in Boston, MA, and Purdue University in West Lafayette, IN, conducted a meta-analysis of trials comparing the effects of meat vs. other diets on our health. The results are published in the journal Circulation. It was an approach that allowed the researchers to not only examine the health effects of red meat, but also see whether substituting red meat for other protein sources brought benefits. Analyzing data from 36 randomized controlled trials, the researchers looked at the blood pressure and blood concentrations of cholesterol, triglycerides, and lipoproteins of the participants. They then compared these levels with those of people who ate less red meat and more chicken, fish, legumes, soy, nuts, or carbohydrates. They found that while there wasn’t much difference in lipoproteins, blood pressure, or total cholesterol, diets high in red meat did cause an increase in triglyceride concentrations. In addition, diets rich in high-quality plant protein led to lower levels of bad cholesterol. Speaking about the findings of the research, Marta Guasch-Ferré, lead author of the study and research scientist in the Department of Nutrition at the Harvard T.H. Chan School of Public Health, said: “Previous findings from randomized controlled trials evaluating the effects of red meat on cardiovascular disease risk factors have been inconsistent. “But, our new study, which makes specific comparisons between diets high in red meat versus diets high in other types of foods, shows that substituting red meat with high-quality protein sources lead to more favorable changes in cardiovascular risk factors.”
Previous claims that one or two alcoholic drinks a day doesn’t do any harm and could actually be protective are now in significant jeopardy following the publication of a large genetic study in The Lancet. According to the UK and Chinese researchers who followed 500,000 Chinese people over a 10-year period, the findings of the study are the best evidence yet on the direct effects of alcohol. While the negative health implications of heavy drinking are understood, the impact of consuming small amounts of alcohol on a regular basis has remained unclear. The researchers, from the University of Oxford, Peking University and the Chinese Academy of Medical Sciences, found that: drinking one to two alcoholic drinks every day increased stroke risk by 10-15% drinking four alcoholic drinks every day increased stroke risk by 35% For the purposes of the study, one drink was defined as either: a small glass of wine a bottle of beer a single measure of spirits In other words, even light-to-moderate drinking can increase blood pressure and a person’s chances of having a stroke. Prof David Spiegelhalter, from the University of Cambridge, said drinking alcohol on a daily basis gives the “opposite effect of taking a statin” (drugs that are used to lower cholesterol levels). The bottom line, according to Prof Richard Peto, professor of medical statistics and epidemiology at the University of Oxford, is the “claims that wine and beer have magical protective effects is not borne out”.
Our daily diets are bigger killers than smoking and account for one in five deaths around the world. In other words, the food you eat could be sending you to an early grave. But which diets are the worst? Well, according to an influential study in The Lancet, salt – whether it be in bread, processed meals or soy sauce – shortens the most lives. The Global Burden of Disease Study used estimates of different countries’ eating habits to determine which diets were shortening the most lives. Here are the three most dangerous diets: Too much salt - three million deaths Too few whole grains - three million deaths Too little fruit - two million deaths Low levels of seeds, nuts, vegetables, fibre and omega-3 from seafood were the other major killers. Speaking to the BBC, Prof Christopher Murray, the director of the Institute for Health Metrics and Evaluation at the University of Washington, said: “We find that diet is one of the dominant drivers of health around the world, it's really quite profound.” Salt is such a big problem because it significantly increases a person’s blood pressure, which in turn increases their chances of heart attacks and strokes. Around 10 million out of the 11 million diet-related deaths were because of cardiovascular disease, highlighting why diets containing too much salt are such a problem.
A new study has revealed that half of UK adults cannot name a single dementia risk factor. If asked, how many could you name? The study by Alzheimer's Research UK found that just 1% of UK adults could name the seven known dementia risk or protective factors. Heavy drinking, smoking, genetics, high blood pressure, depression and diabetes are the six dementia risk factors, while physical exercise is a protective factor. According to the study, more than half of UK adults know someone with dementia, yet only half also recognised that the disease is a cause of death. Furthermore, a fifth of people quizzed for the report incorrectly said that dementia is an inevitable part of getting old. Right now, there are more than 850,000 people in the UK living with dementia and that number is expected to top one million by 2025. Alzheimer's disease is the most common type of dementia, accounting for around two-thirds of all cases. Hilary Evans, chief executive of Alzheimer’s Research UK, said: “It is a sad truth that more people are affected by dementia than ever before and half of us now know someone with the condition. Yet despite growing dementia awareness, we must work harder to improve understanding of the diseases that cause it.” You can read the full Alzheimer’s Research UK report here: https://www.dementiastatistics.org/wp-content/uploads/2019/02/Dementia-Attitudes-Monitor-Wave-1-Report.pdf#zoom=100
People who have sedentary jobs could significantly boost their lifespans by taking short, regular movement breaks, a new study has found. It’s no secret that individuals who spend a lot of time sitting down are more likely to develop certain adverse health conditions, such as diabetes, obesity and cardiovascular diseases, as well as having increased risk of osteoporosis, depression, anxiety, colon cancer and high blood pressure. However, just a small amount of exercise, the study suggests, could lower the risk of early death. According to the research – the findings of which are published in the Annals of Internal Medicine – individuals who sat for less than 30 minutes at a time had the lowest risk of early death. For example, workers who had a movement break (involving some low-intensity exercise) every 30 minutes had a 17% lower risk of death than their counterparts who did not have any breaks. Moreover, individuals who broke up periods of sitting every 30 minutes with moderate- to high-intensity exercise lowered their risk of early death by 35%. Speaking about the findings of the research, Keith Diaz, an assistant professor of behavioural medicine at Columbia University Vagelos College of Physicians and Surgeons in New York City and study lead, said: “If you have a job or lifestyle that involves a lot of sitting, you can lower your risk of early death by moving more often, for as long as you want and as your ability allows — whether that means taking an hour-long high-intensity spin class or choosing lower-intensity activities, like walking.”
The inevitable abundance of food and alcohol you consumed over the festive period has probably left you feeling as though you need to detox a little now the New Year is here. One of the simplest ways to do this is by choosing to not drink alcohol for the entire month of January. Started by UK-based charity Alcohol Change UK, Dry January, as it is known, has become something of a widespread phenomenon, with an estimated 4.2 million people in the UK alone expected to participate this year. Taking part is easy. All you have to do is not drink any alcoholic drinks throughout the month of January. If you’ve curbed your drinking already this month, well done! If you haven’t, it’s not too late to start. Here are some of the health benefits of quitting alcohol for at least a month: Save money (alcoholic drinks can be expensive) Improve your general health (you can potentially lower your blood pressure and cholesterol) Promote weight loss (alcoholic drinks contain plenty of calories) Sleep better (alcohol is not your best friend when you want a good night’s sleep) Improve your long-term relationship with alcohol (prove to yourself that you don’t need it and don’t have to rely on it going forward) Are you up for the Dry January challenge? It’s only for a month and the potential health benefits speak for themselves.
How’s your blood pressure? Do you even know? If you haven’t had it checked recently, your blood pressure could be creeping up (getting higher) and you might not have even realised. In fact, high blood pressure (also known as hypertension) is often called a “silent killer” because it rarely causes symptoms until a person’s health is already severely damaged. That’s why keeping an eye on your blood pressure and looking out for any potential symptoms is so important. Failure to seek treatment when you have high blood pressure can lead to serious health complications such as stroke and heart disease. This is ironic when you consider that hypertension can usually be treated with lifestyle changes and/or medication. So what high blood pressure warning signs should you be looking out for? First and foremost, the only way to check whether you have high blood pressure or not is to have it checked by a health professional, or check it yourself providing you know how to and have the necessary equipment. Remember, just because you feel ‘fine’ does not mean you aren’t at risk of hypertension. If your blood pressure becomes extremely high (above 180/120 mmHg), something referred to as ‘hypertensive crisis’, you may experience any of the following symptoms: Severe headaches Nosebleeds Severe fatigue Chest pain Irregular heartbeat Vision problems Back pain Severe anxiety Blood in your urine Shortness of breath (difficulty breathing) Hypertensive crisis is a medical emergency and immediate intervention is required to prevent serious damage to blood vessels and major organs. So, in short, you are unlikely to know whether you have elevated blood pressure or not until serious damage has occurred. Get your blood pressure checked regularly and heed any advice from medical professionals on how to keep yours at a healthy level.
Alcohol and the amount people drink is the frequent focus of medical studies. However, studying alcohol consumption often results in mixed findings. For example, while drinking too much alcohol can result in liver disease and high blood pressure, other studies have shown that a glass of beer or wine a day can help people live longer. [Related reading: Drinking alcohol while breastfeeding: new study shows possible child cognitive development impact] Now a new study suggests people who abstain from alcohol in middle age may have a heightened risk of dementia later in life. The long-term study, which tracked the health of more than 9,000 civil servants in London, found that middle-aged people who drank over the recommended alcohol limit each week and those who abstained completely were more likely to develop dementia. Specifically, abstinence in midlife was associated with a 45% greater risk of developing dementia compare to people who drank between one and 14 units of alcohol per week. But before you reach for a glass of wine, it should be noted that early life alcohol consumption was not taken into account for the study. People who are teetotal in midlife may have a history of heavy alcohol consumption in their younger years. Indeed, Dr Sara Imarisio, the head of research at Alzheimer’s Research UK, said: “As this study only looked at people’s drinking in midlife, we don’t know about their drinking habits earlier in adulthood, and it is possible that this may contribute to their later life dementia risk.” The results of the study were recently published in the British Medical Journal (BMJ).
Doctors should take a person’s marital status into account when assessing their risk of heart attack and stroke, a major study has found. For the study, researchers at Keele University analysed numerous trials involving more than two million people. They found that individuals who were never married, divorced or widowed were 42% more likely to develop cardiovascular disease. They were also 42% more likely to die from heart disease and 55% more likely to die from a stroke. Risk factors such as age, sex, high cholesterol, high blood pressure, smoking, and diabetes are usually associated with cardiovascular disease. However, the findings of the new study suggest marital status should also be added to the list. Senior author, Mamas Mamas, Professor of Cardiology at Keele University, in England, said: “Our work suggests that marital status should be considered in patients with or at risk of developing cardiovascular disease, and should be used alongside more traditional cardiac risk factors to identify those patients that may be at higher risk for future cardiovascular events”. The researchers say the reason marriage could have a protective effect on cardiovascular disease is because of the additional emotional and social support that’s afforded by having a spouse. People with long-term partners are more likely to have symptoms spotted earlier and encouraged to seek medical advice as a result.
Have you ever encountered someone who calls themself ‘fat but fit’? It’s not uncommon to meet people who are clearly overweight, yet not perturbed by their situation because they consider themselves to be fit and healthy. However, a large study conducted in America has found that women who are overweight or obese but otherwise healthy are still at an increased risk of cardiovascular disease (CVD). For the study, researchers from the German Institute of Human Nutrition Potsdam-Rehbruecke tracked the health of some 90,257 women in the US over a 30-year period. They found that women who were overweight or obese, but had none of the typical cardiovascular risk factors, such as high blood pressure, excess cholesterol and diabetes, were 20% and 39% more likely to develop cardiovascular disease than their normal weight and metabolically healthy peers. Speaking about the findings of the study, Prof Matthias Schulze, who led it, said: "Our large cohort study confirms that metabolically healthy obesity is not a harmless condition, and even women who remain free of metabolic diseases for decades face an increased risk of cardiovascular events.” The study also found women who were of normal weight, but metabolically unhealthy, were over two-times more likely to develop cardiovascular disease than their peers of the same weight who were metabolically healthy. Jeremy Pearson, associate medical director at the British Heart Foundation, added: "This large scale study confirms that obesity, even if unaccompanied by other warning signs, increases risk of cardiovascular disease in women."
While a low sperm count and problems with sperm quality are huge hurdles for couples who are trying to get pregnant, a new study shows that men with low sperm counts are also at increased risk of illness. The study of 5,177 men in Italy found that those with low sperm counts were 20% more likely to have more body fat, more "bad" cholesterol and higher blood pressure – all factors that increase the risk of developing diabetes, heart disease and stroke. They were also 12 times more likely to have low testosterone levels. Dr Alberto Ferlin, from the University of Bresci, who led the study, said: "Infertile men are likely to have important co-existing health problems or risk factors that can impair quality of life and shorten their lives. "Fertility evaluation gives men the unique opportunity for health assessment and disease prevention." The study’s authors say that men with low sperm counts should be actively checked for other potential health problems, which may have a greater chance of being rectified if treated earlier. However, the authors of the study stressed that their findings did not prove that low sperm counts cause metabolic problems, merely that the two are linked in some way.
Do you know how much salt you consume on a daily basis? If you’re a fan of Chinese takeaway meals, it could be far more than you ever imagined, according to a campaign group. For their research, Action on Salt analysed more than 150 Chinese takeaway dishes from both restaurants and supermarkets. They found that most contained way too much salt – almost half the average person’s recommended daily amount of salt (6g) in some cases. When it comes to the saltiest meals, dishes like beef in black bean sauce topped the list. If a person adds a portion of egg fried rice, their salt intake could rise by as much as 5.3g in one meal. In fact, one portion of beef in black bean sauce and a side of vegetable noodles was found to contain as much salt as five Big Macs. While it’s vastly more difficult with Chinese takeaway food, Action on Salt recommends people check the nutritional information on supermarket bought food to see how much salt it contains. The campaign group says that many Chinese takeaway meals should carry health warnings because of the amount of salt they contain. Too much salt can lead to increased blood pressure, which can in turn increase a person’s risk of heart attack and stroke. Public Health England (PHE) has been encouraging the food industry to reduce the amount of salt found in food. Dr Alison Tedstone, chief nutritionist for PHE, said: "A loaf of bread has 40% less than it used to. "However, some products are still too high in salt and we know this can be reduced further. "We've been very clear with the food industry on the importance of meeting the 2017 salt targets. "We'll report on their progress this year and on any necessary advice to government on the next steps." So, the next time you reach to grab your favourite Chinese takeaway meal from the supermarket, just have a quick read of the nutritional information. What you discover might just make you choose something else instead.
A study by Public Health England looking at the heart health of the nation has found that thousands of men face early death at the hands of a heart attack or stroke. In fact, according to the analysis of 1.2 million people, one in 10 British men has a heart age that’s a decade older than their actual age. Heart disease is the main cause of death among men and the second among women. Public Health England says that 7,400 people will die from heart disease or stroke this month alone. However, most of these deaths are preventable and Public Health England says that just a few small lifestyle changes can have a positive impact. One of the suggestions made was for over 50s to get their blood pressure regularly checked as high blood pressure can be an early sign of a potentially life-threatening condition. Public Health England’s head of cardiovascular disease, Jamie Waterall, urged people not to only start considering their heart health later in life. "Addressing our risk of heart disease and stroke should not be left until we are older", he said. How to improve your heart health: Give up smoking Get active Manage your weight Eat more fibre Eat five portions of fruit and vegetables per day Cut down on saturated fat Cut down on salt Drink less alcohol
People who are overweight or obese, despite appearing medically healthy, are still at increased risk of heart disease, experts warn. The notion that people can be ‘fat but fit’ is being challenged by research published in the European Heart Journal. According to the researchers from Imperial College London and the University of Cambridge, who studied health data relating to more than half a million people in 10 European countries, weight is still a heart disease risk factor even if someone has normal blood pressure, cholesterol and blood sugar levels. The study found that people who appeared healthy, with healthy blood pressure, cholesterol and blood sugar readings, were still 28% more likely to develop heart disease than individuals with health bodyweights. Even more at risk were people who were overweight or obese and had high blood pressure, cholesterol and blood sugar levels. Dr Ioanna Tzoulaki, from Imperial's School of Public Health, said: "I think there is no longer this concept of healthy obese. "If anything, our study shows that people with excess weight who might be classed as 'healthy' haven't yet developed an unhealthy metabolic profile. "That comes later in the timeline, then they have an event, such as a heart attack”. So the advice if you want to maintain a healthy heart is to watch your weight, even if you think you are fit.
A study of nearly a million UK adults has found that being married appears to be good for your health, boosting your chances of survival if you have a major heart risk factor, like high cholesterol. All of the individuals involved in the study had high blood pressure, cholesterol or diabetes and the researchers discovered the ones who were married fared much better than those who were single. Dr Paul Carter and colleagues from Aston Medical School presented the findings of their study at the British Cardiovascular Society conference. They believe that having something special in your life is what’s important, rather than simply being married. At the end of their 14-year ACALM study, the researchers found that married men and women in their 50s, 60s and 70s with high cholesterol had a 16% greater chance of being alive than their single counterparts. Dr Carter said: "We need to unpick the underlying reasons a bit more, but it appears there's something about being married that is protective, not only in patients with heart disease but also those with heart disease risk factors. "We're not saying that everyone should get married though. "We need to replicate the positive effects of marriage and use friends, family and social support networks in the same way." Dr Mike Knapton, of the British Heart Foundation, said: "The take-home message is that our social interactions, as well as medical risk factors such as high blood pressure, are important determinants of both our health and wellbeing. "Whether you are married or not, if you have any of the main risk factors for heart disease, then you can call upon loved ones to help you to manage them."
People with non-O blood could be at greater risk of stroke and heart attack, research suggests. Scientists say it's because A, B and AB blood contains higher levels of a blood-clotting protein. The research, which was presented at the 4th World Congress on Acute Heart Failure, analysed studies involving 1.3m people. It found that people 15 in 1,000 people with non-O blood suffered a heart attack, compared to 14 in 1,000 people with O blood. While these figures don't sound that startling at first, when applied to a whole population the numbers become more important. It is hoped that the findings will help doctors better identify who is at risk of developing heart disease. However, Dr Mike Knapton, associate medical director at the British Heart Foundation, said the findings would not have a large impact on the current advice issued by the charity. "Most of a person's risk estimation is determined by age, genetics (family history and ethnicity) and other modifiable risk factors including diet, weight, level of physical activity, smoking, blood pressure, cholesterol and diabetes. "People with a non-O blood group type - AO, BO and AB - need to take the same steps as anyone wanting to reduce their CVD risk." So regardless of your blood type, the advice remains the same: improve your diet, weight, level of physical activity and don't smoke. In addition, manage blood pressure, cholesterol and diabetes too. There's nothing you can do about your blood group, but you can make positive lifestyle changes to reduce your risk of heart attack and stroke.
Half of people labelled 'obese' because of their body mass index (BMI) scores are actually healthy, according to new research, bringing into question the validity of the scoring system. Scientists claim the BMI scoring system is wrongly labelling millions of people 'unhealthy' when, in fact, they are actually much healthier than their slimmer counterparts. Dr. A. Janet Tomiyama, an assistant professor in the department of Psychology at the University of California, Los Angeles, said: "Many people see obesity as a death sentence. But the data shows there are tens of millions of people who are overweight and obese and are perfectly healthy." Scientists say that BMI is being used by healthcare companies to increase premiums in some countries and that the latest findings will be "the final nail in the coffin for BMI." The problem with BMI is that it can give people false hope. For example, a person can have a 'normal' BMI, yet be at risk of disease, highlighting that it is not always an accurate predictor of future health. Prof Tomiyama and her colleagues discovered that more than 54 million Americans are being labelled as "unhealthy," even though they are not. The study - the results of which were published in the International Journal of Obesity - analysed the link between BMI and several health indicators, including blood pressure and glucose, and cholesterol and triglyceride levels. It found nearly half of Americans who are labelled 'overweight' because of their BMIs (34.4 million people) are healthy, as are 19.8 million who are considered 'obese'.
It is something many people will be considering in the New Year, but the plethora of diet advice available out there can be confusing and contradictory. That's why the Mayo Clinic in Arizona set out to see which of the so-called 'low-carb' diets in the weight loss market is the most effective and, more importantly, how safe they all are. They published the results of their study in The Journal of the American Osteopathic Association. Their analysis of some 41 trials that evaluated the weight loss effects of low-carb diets found that individuals lost between 2.5-9 more pounds than individuals who followed a low-fat diet. Dr. Heather Fields, an internal medicine physician at Mayo Clinic and lead researcher on the study, said that adhering to low-carb diets in the short-term appears to be safe and promotes weight reduction. "However, that weight loss is small and of questionable clinical significance in comparison to low-fat diets. We encourage patients to eat real food and avoid highly processed foods, especially processed meats, such as bacon, sausage, deli meats, hot dogs, and ham when following any particular diet," she added. This is the biggest warning to come out of the research and it's because when people are following low-carb diets they tend to eat more meat, and this could increase their risk of death from all causes, including cancer - especially if they consume a lot of processed meat. Nevertheless, the studies showed that compared with many other diets, low-carb ones were effective for weight loss without adverse effects on blood pressure, glucose, and cholesterol.
A new study has found that men are much more likely to suffer a cardiac arrest than women. In fact, around one in nine men will have their heart stop suddenly before the age of 70, compared to around one in 30 women. The study researchers said that by the age of 45, men have almost an 11% lifetime risk of sudden cardiac arrest. Women of the same age have just a 3% risk. According to Dr. Donald Lloyd-Jones, chair of preventive medicine at the Feinberg School of Medicine, in Chicago, approximately 450,000 Americans die from sudden cardiac arrest each year, and most never have any of the usual symptoms associated with a heart problem. He explained that because heart disease tends to develop earlier in men than in women, more serious screening for risk factors in the male population needs to be undertaken. Smoking, high cholesterol, high blood pressure and diabetes are all major cardiac arrest risk factors. "Know your numbers, especially your blood pressure, but also know your cholesterol or whether you have diabetes," said Dr. Lloyd-Jones. "At 50, men should also have a baseline electrocardiogram, which might reveal heart problems," he added. For the study, Dr. Lloyd-Jones and his colleagues analysed data on more than 5,200 men and women between the ages of 28 and 62 who took part in the long-running Framingham Heart Study.
It's been widely accepted for some time that a high-salt diet may increase a person's risk of having a stroke or a heart attack. But now a new study has found that a low-salt diet may also be just as dangerous. Published in The Lancet, the findings of the study suggest that people who have a low salt or sodium intake may be increasing their risk of cardiovascular disease, compared to those who have an average intake. In fact, the study, which was conducted by researchers at McMaster University and Hamilton Health Sciences, says that the only people who should look to reduce their salt consumption are those with high blood pressure. Furthermore, the researchers say that current salt consumption guidelines may be too low, and should be reviewed going forward. At present, it is recommended that Americans consume no more than 2,300mg of salt each day, which is about 1 teaspoon. However, around 90% of US adults exceed this recommendation on a regular basis, according to a report from the Centers for Disease Control and Prevention (CDC) released earlier this year. On the other hand, the World Health Organisation (WHO) recommends people eat between 5 and 6g of salt each day. The lead author of the study, Andrew Mente, said: "While our data highlights the importance of reducing high salt intake in people with hypertension, it does not support reducing salt intake to low levels." Despite the study focusing on 130,000 people across 49 countries, its methods have been criticised by experts, while others have questioned the study's findings. The bottom line? Salt should be consumed in moderation, and people with high blood pressure should seek specific medical advice to find out what is best for them.
For someone with high blood pressure, drinking alcohol - even just small amounts - can impact how the lower left chamber of the heart functions, according to a new study from Italy. Researchers found that if a person has high blood pressure, even consuming as little as an ounce of alcohol a day can affect the chamber of the heart that pumps blood to the rest of the body. Lead researcher Dr. Leonardo Sechi said: "Because even moderate alcohol consumption increases occurrence of early functional cardiac changes in patients with [high blood pressure], reduction of use of alcoholic beverages might be beneficial for prevention of cardiac complications in these patients." At present, the cause of this heart damage remains unknown, and further studies will be needed to uncover the exact cause-and-effect relationship, said Sechi. A staggering one-third of US adults have high blood pressure (also referred to as hypertension) today, and it accounts for approximately 1,000 deaths per day in the country. The researchers discovered that the study participants who consumed the most alcohol had thicker left ventricular walls, which stiffened the chamber making it function less effectively. Basically, the more people drank the more difficulty their hearts had filling with blood in between each heartbeat. It should be noted that until the results are published in a peer-reviewed journal, they should be considered preliminary.
A new study has revealed that heart attack victims in the United States are becoming younger and fatter. Over the past two decades alone, the average age of people suffering the deadliest heart attacks has fallen from 64 to 60, and obesity has been implicated in 40% of the most severe, according to researchers at Cleveland Clinic, Ohio. In addition, heart attack sufferers nowadays are more likely to be smokers and people with high blood pressure, diabetes and chronic obstructive pulmonary disease (COPD), compared to 20 years ago. It's a reality that is raising alarm bells. "Lifestyle changes to reduce weight, eat right, exercise and quit smoking are critical for prevention of heart attack," said senior researcher Dr. Samir Kapadia, an an interventional cardiologist in the Cleveland Clinic Department of Cardiovascular Medicine at Cleveland Clinic. Dr. Kapadia added that the responsibility for making these lifestyle changes should be shared between the patient and their medical doctor, and the issue discussed at routine checkups. The study focused on analysing heart disease risk factors among more than 3,900 patients; all of whom had been treated for an ST-elevation myocardial infarction (STEMI). One of the most severe types of heart attack, STEMIs often result in disability or death and occur when the heart's main artery is completely blocked by plaque. The results of the study are scheduled to be presented on April 4 at the American College of Cardiology's annual meeting in Chicago.
The benefits of weight loss surgery have been known for quite some time now and it’s a procedure that has helped many people regain their confidence and start living normal lives again. However, new research has shown that people with metabolic syndrome are more prone to lower urinary tract problems and that weight loss surgery can be used to significantly improve lower urinary tract symptoms. The first of the two studies was conducted by Dr. François Desgrandchamps and his colleagues at the Saint-Louis Hospital in Paris, France. They studied 4,666 men over a period of 12 days in 2009 and found that there was a strong link between metabolic syndrome and lower urinary tract symptoms. Furthermore, lower urinary tract symptoms were more severe in men with metabolic syndrome. The second study, conducted by a team at Wakefield Hospital in New Zealand, analysed 72 weight loss surgery patients before and after their procedures. They found that after just 6 weeks patients with lower urinary tract symptoms showed significant improvement. Metabolic syndrome is thought to affect around 34% of adults in the U.S. and puts them at greater risk of strokes, heart attacks, type 2 diabetes and cardiovascular disease. It is diagnosed when an individual displays three or more metabolic risk factors, which include high cholesterol, high blood pressure, abdominal obesity and high blood glucose levels.

As we get older, our bodies need a bit more TLC to ensure we’re fighting fit for the challenges that life throws at us. Therefore, when we reach the age of 40, there are certain medical tests which are recommended and specifically designed to check your vital systems. Also, these tests will inevitably be accompanied by a series of questions, so that a full picture of your health can be produced. Depending on the results, you may be given personalised advice by your medical professional and instructed to make lifestyle changes going forward. In some circumstances, you’ll be offered medical treatment to help maintain or improve your health. There are three simple tests that will help your medical professional determine your ‘heart age’. These are as follows: Cholesterol test We all need a certain amount of cholesterol for our bodies to function but there is strong evidence to suggest that too much cholesterol – particularly bad cholesterol – increases the risk of vascular diseases. A simple blood test is used to measure your cholesterol and you’ll know the result right away. Blood pressure test The higher your blood pressure the harder your heart has to work to pump blood around your body. This can not only weaken you heart but also increase your chances of developing a blocked artery. Your blood pressure is measured using a cuff that fits around your upper arm and is inflated. BMI test Your BMI or body mass index determines whether you are a healthy weight for your height. People with higher BMIs have a higher chance of developing certain conditions such as heart disease, certain cancers and stroke. Diabetes assessment In addition to the three tests above, a diabetes risk assessment is also recommended for people over 40. Diabetes occurs when your body does not produce enough insulin or when the insulin it does produce is not as effective as it should be. Your medical professional will ascertain through questions and the results of your blood pressure and BMI tests whether you are at risk of type 2 diabetes. A simple blood test will then confirm if your blood sugar is too high.
Gastric Band Surgery for people who are extremely overweight can be a life-changing occurrence. It’s a procedure that puts in place an adjustable lap band around the upper part of the stomach to restrict its size and slow down the passage of food, making them feel fuller, sooner. The major obvious benefit is the weight loss that patients can expect to see. This is normally around 50% of the original excess weight and often occurs within the first year, but can carry on into the second. In addition, Gastric Band Surgery does not require the patient to follow a strict diet, since the band will reduce the amount of food intake naturally, making it easier than many other weight loss solutions. The procedure itself is considered relatively low risk and since it is often carried out using keyhole surgery, the recovery time is reasonably quick. A standard hospital stay is just one or two nights and most patients can be back to normal activities within a week to ten days. Aside from this weight loss benefit where patients will feel better, have improved confidence and self-esteem and be happier in general, there are major additional health benefits associated with Gastric Band Surgery. No longer will the patient be at high risk of infertility, diabetes, heart disease, high blood pressure, stroke and arthritis. So it really is a long term solution for those who are extremely overweight without posing any health risks. If you’d like to find out more about Gastric Band Surgery, contact France Surgery today.
