Diabetes has long been split into two types: type 1 and type 2. But new research suggests it could actually be five different diseases and treatment could be tailored to tackle each form. Researchers in Sweden and Finland say the more complicated diabetes picture they’ve uncovered could lead to a new era of personalised medicine being ushered in. Affecting approximately one in 11 people around the world, diabetes doesn’t just play havoc with blood sugar levels, but also increases the risk of stroke, blindness, heart attack, kidney failure and limb amputation. Type 1 diabetes, which affects around 10% of sufferers in the UK, is a disease of the immune system that attacks the body’s insulin factories, leading to there being a shortage of the hormone to control blood sugar levels. Type 2 diabetes, on the other hand, is associated with poor lifestyle choices and obesity, which affect the way in which insulin works. For the study, the researchers analysed blood samples from 14,775 patients. They found that people could be separated into five distinct diabetes clusters. Talking to the BBC, Prof Leif Groop, one of the researchers, said: "This is extremely important, we're taking a real step towards precision medicine. "In the ideal scenario, this is applied at diagnosis and we target treatment better."
