unintentional weight loss vs. intentional weight loss

Unintentional weight loss is one of the signs of uncontrolled DM (Diabetes Mellitus), esp. in type I with which your pancreas fail to produce any insulin and thus the body cant use glucose from food for energy storage. Therefore, your muscle and fat start to breakdown for energy. The high level of glucose and other stuffs from the irregular metabolism in the blood stream brings along water with it (jargon: osmotic diuresis)and make the patient pee a lot and thus weight loss.

Intentional weight loss is beneficial for Type II DM. Obesity and a strong family history suggest high risk for developing type II. In type II, the insulin level could be higher than normal but they are not functional. It is called insulin resistance which occurs when you have excess fat and that could eventually lead to type II diabetes in some patient.Intentional weight loss by exercise and diet can increase the sensitivity of insulin and thus beneficial.

Type I vs. Type II

Type I is insulin dependent which means the patient requires insulin injection. This is a immune related process. Type II is not insulin dependent and usually be dealt with life style change, medication.Type I and II are considered as 2 quite different disease processes.
