Type l diabetes often occurs in younger people (it used to be called juvenile-onset diabetes) and affects about 1 million Americans. It is caused by decreased or no insulin production by the pancreas. The high blood levels of glucose (called hyperglycemia: hyper means “high,” give means “sweet,” emia means “in the blood”) must be regulated by insulin injections to compensate for the deficiency of insulin production.
Type II diabetes is much more common than type I diabetes. It is known to affect at least 7 million Americans. Another 5 to 7 million people probably have type II diabetes but are unaware of it. More than 75 percent of people who have type II diabetes are over- weight. Evidently, obesity is a “trigger,” causing diabetes to develop in genetically vulnerable people. For them, the problem is both a deficiency of insulin and an inability of their body’s cells to respond appropriately to the insulin that is there. Evidence is mounting that exercise lowers the risk of type II diabetes developing, even in people who are overweight or who have a family history of diabetes. The best treatment for type II diabetes is weight loss, but if this is not achievable, then oral medications, or insulin injections, may be required.
