Diabetes is a chronic (lifelong) disease that keeps your body from turning food into energy—which causes you to have high blood sugar (glucose) levels.
The three most common types of diabetes are:
- Type 1 diabetes (body does not produce insulin)
- Type 2 diabetes (body does not produce or use insulin efficiently)
- Gestational diabetes (occurs during pregnancy)
