Can diabetes be reversed? The truth behind the social media claims

Dubai: Can diabetes really be reversed? It is one of the most searched health questions online, and one of the most misunderstood. Scroll through social media and you will find countless claims: a special diet that allegedly cured diabetes, an exercise programme that supposedly reversed it, or a supplement promising to eliminate the disease altogether. But what does the science actually say? The answer depends largely on the type of diabetes. For people living with Type 1 diabetes , there is currently no cure. It is an autoimmune condition in which the body's immune system destroys the insulin-producing cells in the pancreas, making lifelong insulin treatment necessary. Type 2 diabetes , however, is different. The condition develops when the body becomes resistant to insulin and struggles to regulate blood sugar effectively. While it remains a chronic disease, doctors say some people can achieve a state known as remission, where blood glucose levels return to the non-diabetic range without medication. The crucial word, however, is not ' cure '. It is ' remission '. Why doctors avoid the word 'cure' Dr Nishanth Sanalkumar, a Consultant Endocrinologist with more than 20 years of international experience, says social media often oversimplifies what is actually a complex medical condition. "Type 2 diabetes accounts for more than 90 per cent of people with diabetes worldwide," he says. According to Dr Sanalkumar, excess body fat — particularly around and within the liver — is one of the major drivers of insulin resistance. Combined with sedentary lifestyles and unhealthy dietary habits, it can contribute to obesity, fatty liver disease and eventually Type 2 diabetes. The encouraging news is that significant weight loss can reduce insulin resistance and restore blood glucose levels to normal in some patients. "If a person can achieve normal glucose levels and maintain them for at least three months without any diabetes medications, we can say that he or she has achieved diabetes remission," he says. Dr Brian Mtemererwa, Consultant Endocrinologist and Medical Director with more than 27 years of experience, says remission has a specific medical definition. "International experts define remission as maintaining an HbA1c below the diagnostic threshold for diabetes — less than 6.5 per cent or 48 mmol/mol — for at least three months without glucose-lowering medication," he says. "The underlying susceptibility to diabetes has not disappeared. Rather, the disease has become metabolically inactive through successful treatment and lifestyle change." Both specialists emphasise that remission is not the same as a cure. "We prefer the term remission rather than reversal or cure because cure implies the problem has permanently disappeared, and that's not necessarily true," says Dr Sanalkumar. If weight is regained and unhealthy habits return, blood sugar levels can rise again and diabetes may recur. Even after remission, patients require ongoing monitoring for complications affecting the eyes, kidneys, cardiovascular system and other organs. What the evidence shows Research over the past decade has significantly changed how doctors view Type 2 diabetes. One of the most influential studies was the DiRECT trial, which demonstrated that intensive weight-management programmes using very low-calorie meal replacement diets enabled many participants to achieve remission. Dr Nishanth Sanalkumar, a Consultant Endocrinologist with more than 20 years of international experience "The evidence is now very clear that substantial weight loss can lead to diabetes remission in a significant number of people," says Dr Sanalkumar. The likelihood of remission increases considerably among patients who achieve weight loss of approximately 10 to 15 per cent or more. Dr Mtemererwa notes that the timing of intervention is equally important. "One message consistently emerges from modern research: the earlier intervention begins after diagnosis, the greater the likelihood of remission," he says. Patients who still retain good pancreatic beta-cell function generally have a much higher chance of restoring normal glucose control than those with long-standing diabetes. Why there is no miracle diet One of the biggest misconceptions surrounding diabetes is the belief that a single dietary approach can reverse the condition for everyone. "There is no miracle diet," says Dr Mtemererwa. Mediterranean diets, lower-carbohydrate eating plans, calorie-restricted programmes and medically supervised meal replacement programmes have all shown benefits in appropriate patients. "What they have in common is not the name of the diet, but their ability to help people achieve sustainable weight loss and healthier eating habits." He warns patients to be sceptical of herbal remedies, detox products and expensive supplements promoted as diabetes cures. "There is no convincing scientific evidence that these products can eliminate Type 2 diabetes." The doctors are equally concer
