Several factors are responsible for insulin resistance (Insulin threat, December 26) in Indians. Over-indulgence on high-carbohydrate foods, sedentary lifestyle and genetic predisposition are the principal reasons that make South Asians suffer either from impaired glucose tolerance or full-fledged Type 2 diabetes. These problems arise due to the inability of insulin to push glucose from blood into the body cells for energy production. This is called insulin-resistance which leads to accumulation of plenty of glucose in blood (hyperglycemia). Hyperglycemia leads to an array of disorders like coronary artery disease and cerebral stroke. To preserve our health, we Indians should immediately keep a strict check on our diet. We have to reduce carbohydrate and fat in our diet and go for regular physical exercise.
