Diabetes Mellitus refers to a group of metabolic diseases that affects a person. A person has high blood sugar levels, either because the cells do not respond to the insulin production or because the body does not produce enough insulin. It is of three types i.e. Type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus, and Gestational Diabetes.

Type 1 Diabetes Mellitus: Type 1 diabetes results when the body fails to produce insulin. This
requires a person to inject insulin.
Type 2 Diabetes Mellitus: This occurs as a result of insulin resistance. It is a condition where
the cells fail to use insulin. This sometimes results in an absolute insulin deficiency. This was
previously called non insulin-dependent diabetes mellitus (NIDDM). It was also called adult-
onset diabetes.
Gestational Diabetes: This is seen among women during pregnancy without a previous
diagnosis of diabetes. They develop a high blood glucose levels.

reason for each type of diabetes may be different, too much of glucose is always dangerous. So, read
