The pancreas produces insulin in reply to an infusion of blood sugar levels. The insulin is responsible for assuring your cells get the glucose they need to function. However, an excessive amount of sugar in your diet during a period of time may cause your cells to become resistance against the insulin. As a result they just don't receive adequate nutrition as well as your blood glucose levels remain high forcing the pancreas to work even harder to do its job. If this situation persists you may almost definitely develop diabetes type 2. If you have past diabetes it is just as vital if not more to to deal with your pancreas.
