Diabetes Mellitus (DM) is a chronic metabolic disease characterized by elevated levels of blood glucose (sugar). It is the result of hormonal imbalance, obesity, heredity and bad lifestyle. Normally, blood glucose levels are tightly controlled by insulin, a chemical (hormone) substance produced by a gland called pancreas located near the stomach. Insulin lowers the blood glucose level by stimulating the body to make use of glucose. But in case of diabetes, the glucose obtained from the food remain in the blood stream, instead of being used by the cells for energy production. This affects heart, kidney, liver, eyes, legs, and all other body parts.
