Diabetes Mellitus is caused due to the lack of insulin or hyposecretion of insulin. There are two types of diabetes mellitus viz type 1 diabetes mellitus and type 2 diabetes mellitus. The type 1 diabetes mellitus is also called Insulin Dependent Diabetes Mellitus (IDDM). The type 2 diabetes mellitus is called Non-Insulin Dependent Diabetes Mellitus (NIDDM).
