Diabetes Mellitus

DM is broadly classified into type 1 and type 2 depending on its cause; in type 1 DM, the Islet cells in the pancreas, the source of Insulin is destroyed by the patient’s own defense mechanisms (immune system); in type 2 DM, there are defects in insulin secretion and action. Type 1 DM predominantly develops before the age of 30 and type 2 DM, after the age of 30 years. However, this is not a rule; type 1 DM may appear after 30 years of age and vice versa. Among these types, type 2 DM is more common worldwide.
