Additional information: Diabetes is a chronic disease that occurs when the pancreas no longer produces insulin, or when the body cannot make good use of the insulin it produces. It occurs when the immune cells destroy the insulin-producing beta cells of the pancreas. This disease is also hereditary. High cholesterol and lack of exercise and diet can lead to worsening of the diabetic level in the body.

Note: The disease can be brought under control by having a proper diet and controlling the intake of sugar and food items which can increase the cholesterol level in the body. The patient should regularly check his/her diabetic level to ensure proper health.
