Diabetes mellitus is a disease caused by defective carbohydrate metabolism and characterized by abnormally large amounts of sugar in the blood and urine.
There are three main types of diabetes:
- Type 1 diabetes:results from the body's failure to produce insulin, and presently requires the person to inject insulin. (Also referred to as insulin-dependent diabetes mellitus, IDDM for short, and juvenile diabetes.)
- Type 2 diabetes:results from insulin resistance, a condition in which cells fail to use insulin properly, sometimes combined with an absolute insulin deficiency. (Formerly referred to as non-insulin-dependent diabetes mellitus, NIDDM for short, and adult-onset diabetes.)
- Gestational diabetes:is when pregnant women, who have never had diabetes before, have a high blood glucose level during pregnancy. It may precede development of type 2 diabetes mellitus.
