In type 2 diabetes, there are two main underlying reasons for high blood glucose: insulin resistance[1], a condition in which the body does not use insulin efficiently, and insufficient insulin secretion by the pancreas. People with type 2 diabetes usually do not show signs of autoimmune disease.
Type 2 diabetes usually develops in adults, but it is now occurring with alarming frequency in children. The growing epidemic of obesity in children is believed to be a major contributor to the increase of type 2 diabetes in children. Symptoms of type 2 diabetes are generally the same as those for type 1 diabetes[2], but they may be much milder. In fact, many people with type 2 diabetes are unaware that they have it. Other symptoms may include wounds that heal slowly, frequent infections, and, in adults, sexual dysfunction[3], including impotence.
Treatment for type 2 diabetes may include taking oral medicines[4] to decrease insulin resistance and/or increase insulin secretion and taking other drugs to treat any diabetes-related conditions; it may also include taking insulin. Attention to diet[5] and regular physical activity[6] are important treatment components. Weight loss[7] can also help to reverse insulin resistance and lower blood glucose if a person is overweight.
