Diabetes is a disease in which the body’s blood glucose, or blood sugar, level is too high. Normally, the body breaks down food into glucose and then carries it to cells throughout the body. The cells use a hormone called insulin to turn the glucose into energy.
In type 2 diabetes, the body’s cells don’t use insulin properly. At first, the body reacts by making more insulin. Over time, however, the body can’t make enough insulin to control its blood sugar level.
Diabetes is a leading cause of early death, CHD, stroke, kidney disease, and blindness. Most people who have type 2 diabetes are overweight.
