Diabetes is an endocrine disorder characterized by metabolic abnormalities, especially of the carbohydrate metabolism. Diabetes mellitus occurs when the pancreas secretes insufficient amounts of insulin or when the way the body uses insulin is deficient. Insulin is the hormone that provides the cellular energy needs, through the use of sugar (glucose) by cells.
Many of the symptoms of type 1 diabetes resembles the type 2 diabetes. In both cases there is too much glucose in the blood and failure in your body cells. The high glucose levels of type 1 diabetes are due to a lack of insulin because the cells that produce insulin have been destroyed. Type 2 diabetes occurs when the body becomes resistant to the insulin produced. In any case, the cells in your body are not receiving the amount of glucose they need, and your body will send some warning signals.
