Being obese or overweight increases the chances of someone with COVID-19 experiencing serious illness, complications, and death, new research suggests. Having examined existing studies, Public Health England (PHE) found that carrying excess weight put people at greater risk of requiring hospital admission or intensive care. Furthermore, that risk grew as weight increased. The findings of the PHE evidence review come ahead of an expected UK Government announcement relating to new measures to curb obesity in the country. At present, the UK has some of the highest obesity levels in Europe, with almost two-thirds of adults now either overweight or obese. Many believe that the coronavirus pandemic and subsequent lockdown have served to exacerbate many people’s weight issues, with individuals stuck at home for prolonged periods and unable to carry out their usual exercise regimes. The findings of the evidence review will be of particular concern to groups that are already at higher risk of COVID-related complications, such as older people, black and ethnic minorities, and those living in more deprived areas. Dr Alison Tedstone, chief nutritionist at Public Health England, said the current evidence was clear: “Losing weight can bring huge benefits for health - and may also help protect against the health risks of Covid-19," she said. "The case for action on obesity has never been stronger.”
Gaining weight in later years has a detrimental impact on lung health, a new study suggests. People’s lungs naturally deteriorate as they age and lose functionality as the years go by. But now new research has linked moderate or significant weight gain to an even sharper decline in lung health. According to the study of 3,700 individuals in Europe and Australia, who were recruited between the ages of 20 and 44, and were studied for 20 years, people who gained weight throughout the course of the study – regardless of whether they were a healthy weight or overweight/obese to begin with – had accelerated lung function decline. Furthermore, overweight/obese individuals who lost weight during the study saw their lung functionality decline slow. Publishing their findings in the journal Thorax, the researchers said large amounts of fat in the abdomen and chest can limit the space lungs have when people inhale. It was also suggested that fat produces inflammatory chemicals that can reduce the diameter of airways and damage lungs. Speaking about the findings of the research, study leader Judith Garcia Aymerich, head of the non-communicable diseases and environment program at Barcelona Institute for Global Health (ISGlobal), said: “Although previous research has shown that weight gain is linked to lung function decline, ours is the first study to analyze such a varied population sample over a longer period of time.”
Obesity is worryingly common across the world today. World Health Organization statistics from 2018 show that global obesity has almost tripled since 1975 and most of the world’s population now live in a country where being overweight or obese kills more people than being underweight. But while obesity is known to increase a person’s risk of certain health conditions, new research has revealed that it does not seemingly affect men and women in the same way. According to the study from Oxford University in the United Kingdom, the findings of which are summarized in the journal PLOS Genetics, the risks of developing different health problems as a result of being obese are different for men and women. For example, obese women are at higher risk of developing type-2 diabetes than men. Meanwhile, obese men have a higher risk of chronic kidney disease and chronic obstructive pulmonary disease. The team says their findings add to the existing evidence that preventing and treating obesity is a crucial step in countering the emergence of other health conditions. “This study shows just how harmful carrying excess weight can be to human health, and that women and men may experience different diseases as a result,” said first author Dr. Jenny Censin. For the study, the team from Oxford University analyzed genetic information and three different obesity measures in a cohort of 195,041 men and 228,466 women.
Researchers have found fat in overweight and obese people’s lungs. It’s the first time such a discovery has been made and could provide important clues as to why overweight and obese people have an increased risk of asthma. For the research, a team from Australia analysed lung samples from 52 deceased individuals. They found the amount of fat present increased in line with Body Mass Index (BMI). Being overweight/obese is already linked to having asthma, but it was previously thought that excess weight pressing on the lungs was the main reason for this. However, the Australian researchers say fatty tissue in the walls of airways takes up space and causes inflammation, which can lead to wheezing and asthma. Speaking about the findings of the research, which are published in the European Respiratory Journal, Dr Peter Noble from the University of Western Australia said: “We’ve found that excess fat accumulates in the airway walls where it takes up space and seems to increase inflammation within the lungs. “We think this is causing a thickening of the airways that limits the flow of air in and out of the lungs, and that could at least partly explain an increase in asthma symptoms.” Experts say that more research is now needed to find out whether the build-up of fatty tissue could be reversed through weight loss. In the meantime, asthma patients should be supported to achieve a healthy weight.
If you’re looking to lose some weight, eating earlier in the day and intermittently fasting could help, new research suggests. According to a paper published in the journal Obesity, the timing of meals and intermittent fasting influences metabolism, which can have an impact on weight loss. Researchers discovered this following a trial involving 11 men and women, all of who were in good health, aged between 25 and 45 years and carrying some excess weight. The trial participants were split into two groups: one who ate breakfast at 08:00 and then ate their last meal of the day at 14:00, and another who ate breakfast at 08:00 and had their last meal of the day at 20:00. Both groups ate the same meals each day. At the end of the trial, participants underwent a battery of tests in a respiratory chamber to assess their metabolism. The number of calories, fat, carbohydrates and proteins burned were all measured. It was revealed that the participants who ate their last meal of the day at 14:00 and, therefore, fasted longer overnight, burned more fat than the other group. They also had lower levels of the hunger hormone ghrelin. “Eating in sync with circadian rhythms by eating early in the daytime appears to reduce body weight and improve metabolic health,” the authors of the paper wrote.
By 2043, obesity will surpass smoking to be the biggest preventable cause of cancer in UK women. That’s one of the shocking new predictions to come out of a report by Cancer Research UK. At present, around 7% of cancers in women are linked to being overweight and obese, while 12% are said to be caused by smoking. But as the number of individuals who smoke continues to fall and obesity rates continue to rise, the UK cancer charity believes that gap will completely disappear over the next 25 years (assuming current trends continue). In fact, by 2035, the percentage of cancers caused by smoking and by carrying excess weight will almost be equal (25,000 cancer cases each year related to smoking vs. 23,000 related to being overweight). However, after just another eight years (by 2043), being overweight and obese is likely to be linked to even more cases of cancer in women than smoking. Interestingly, the cancer charity says that obesity will not overtake smoking as the leading cause of cancer in men until some time later. The reason for this, though, is simply because more men than women smoke. While obesity is more prevalent among men too, it is thought to be a greater catalyst in women for developing cancer. Professor Linda Bauld, Cancer Research UK's prevention expert, said the UK government must act now to stem the tide of obesity-related cancers. “That's why we are raising awareness of the link between cancer and obesity and calling for measures to protect children, like a ban on junk food adverts before 9pm and for restrictions on price promotions of 'less healthy' products,” she said. Smoking-related cancers include: acute myeloid leukaemia lung bladder bowel cervical pancreatic stomach Obesity-related cancers include: bowel gall bladder kidney liver breast ovarian thyroid
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.
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. We’ll be with you every step of the way.
Sleeve gastrectomy is a weight loss surgery that will be contemplated for patients who have attempted various other weight loss programmes and techniques. Surgery should be the last option available and only considered once non-surgical treatments have failed. This is because any type of surgery comes with risk and so a person should not undergo surgery unless they need to for medical reasons. The sleeve gastrectomy is a surgery that reduces the size of the stomach and in turn will therefore reduce the amount that a person can eat before they feel full. In France surgeons make a cut into the abdomen and remove the left side of the stomach by anything up to 75%. This leaves the patient’s stomach in the shape of a banana. The surgery can be carried out either by open surgery or keyhole surgery. In order to minimise scarring and reduce recovery time the surgery in France is usually carried out as keyhole surgery. The operation usually takes approximately 2 hours if there are no complications and a stay in hospital of between 3 – 8 days will be necessary depending on recovery time. Research has shown that in France after 2 years patients can have lost 45-64% of their excess weight. Photo credit: © aihumnoi - Fotolia.com
There is a great deal of information to understand before deciding on whether to have gastric bypass surgery. However, knowing a few facts will help you decide if gastric bypass surgery is for you and whether France is the best place for your surgery to take place. Gastric bypass surgery is a very common procedure performed for the purpose of weight loss. The way in which this is achieved is to reduce the size of the stomach by up to 90% and to bypass part of the digestive system so that less food is absorbed. In France this procedure is carried out under general anaesthetic and in most cases by laparoscopy, which leaves fewer scars and generally heals quicker than any alternative. The length of time the operation takes is approximately 2-3 hours and recovery time in hospital is usually between 4-8 days, possibly up to 2 weeks for procedures with no complications. In terms of weight loss, gastric bypass surgery in France is a very successful procedure. On average, patients of French Surgeons experience loss in the region of 70 – 75% of excess weight. There are many options in France for both citizens and international visitors to achieve dramatic weight loss by accessing gastric bypass surgery in a safe, clinical and regulated environment.

There are many types of surgery which are designed to facilitate weight loss. Gastric band weight loss surgery, or gastric banding, is a popular and successful choice. The surgery is carried out under general anaesthetic and usually by a laparoscopic procedure, meaning fewer scars and quicker healing time. On average the surgery takes approximately an hour to complete. A surgeon fits a gastric band onto the patient’s stomach which leaves a small pouch available for food to enter. This means that when the patient eats, they feel full quicker than before the surgery and stop eating sooner. Less food consumption means less weight. The gastric band is fully adjustable after the surgery by passing saline solution through access ports and inflating the band to the required size. Patients can often have the gastric band adjusted for up to 2 years after the procedure has been carried out to ensure that the gastric band remains effective. Gastric banding is an effective procedure for weight loss with average losses of 40-60% of excess weight achieved by French surgeons. When thinking about weight loss surgery, gastric banding should be considered for the fact that it is a relatively simple and quick procedure, with only a few days of recovery time and excellent weight loss results.
