Diabetes mellitus is a group of metabolic diseases characterized by high blood sugar (glucose) levels, which result from defects in insulin secretion, or action, or both. Diabetes mellitus Diabetes is a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime. Individuals are normally capable of digesting carbohydrates, in particular those most common in food; starch, and some disaccharides such as sucrose, are converted within a few hours to simpler forms such as the monosaccharide glucose, the principal carbohydrate energy source used by the body. Insulin is released into the blood by beta cells, located in the Islets of Langerhans in the pancreas, in response to rising levels of blood glucose, usually after eating and is used by approximately two-thirds of the body's cells to absorb glucose from the blood for use as fuel for conversion to other needed molecules, or for storage. Insulin is also the principal control signal for conversion of glucose to glycogen for internal storage in liver and muscle cells. Due to the fact that insulin is the principal hormone that regulates uptake of glucose from the blood into most cells, deficiency of insulin or the insensitivity of its receptors causes hyperglycemia and plays a significant role in all forms of diabetes mellitus. There are two main types of diabetes: type 1 diabetes and type 2 diabetes. Both types may be inherited in genes; therefore, a family history of diabetes can significantly increase a person's risk of developing the condition.
