Diabetes is a chronic medical condition marked by the body’s inability to regulate insulin levels, which can lead to excessive blood sugar. There are three types of diabetes. Type 1 diabetes occurs when the body makes very little insulin or no insulin at all. It typically onsets during childhood or adolescence and must be managed with daily insulin injections. With type 2 diabetes, insulin levels are affected by a patient’s excess weight or obesity. It typically sets in during adulthood. The third and rarest type of diabetes is gestational diabetes, which occurs in pregnant women. It may or may not go away after the affected woman gives birth.
