First, know that you're not alone—nearly 8% of the population in the U.S. has some form of diabetes. Basically, your body has trouble converting sugar into usable energy. In healthy individuals the hormone insulin does this job. Chances are your body is resistant to or can't produce enough insulin. With type 1, an autoimmune disease often diagnosed in children, the pancreas makes no insulin at all and sufferers are treated with insulin shots. The cause of type 2, formerly known as adult onset, is unknown, but is associated with obesity and inactivity. Unfortunately, today young people are also being diagnosed with type 2 (as many as 50% of children with diabetes have type 2).
