DIABETES MELLITUS AND OBESITY

Overweight and obese people keep producing the hormone insulin,but it cannot
act appropriately.An obese person having a high carbohydrate intake puts a strain on the body's glucose metabolism.Also, obesity reduces the insulin receptors on the surface of the cells. As the uptake of insulin is less by fewer
receptors, the body's sensitivity to the insulin is reduced.

Cells (mainly fat or muscle ) requiring glucose, cannot get it from the blood.There is a famine in the midst of plenty, resulting in diabetes.

In response to the high blood sugar present , the pancreas works more to produce more insulin.Eventually, this constant pumping of the pancreas
exhausts the pancreatic beta cells.Insulin secretion from the pancreas starts becoming inadequate and overweight people become diabetic
