Diabetes is a disease that causes consistently high blood sugar because the body fails to process or produce insulin. Insulin enables the body to use or store energy from food. There are three types of diabetes:
- Type 1 diabetes
- Type 2 diabetes
- Gestational diabetes
Type 1 diabetes requires regular administration of insulin and careful regulation of blood sugar through eating and exercise.
Type 2 diabetes is the most common—90% of diabetes patients have Type 2—and it is treated with adjustments to diet, exercise and, in some cases, oral medication.
Gestational diabetes occurs when women have high blood glucose levels during pregnancy. Though gestational diabetes sometimes requires medication or insulin treatments, it is often treated with lifestyle changes and careful monitoring.
