Types of Diabetes

Type 1 diabetes

Type 1 diabetes, previously known as juvenile diabetes, is an autoimmune disease in which the body does not produce the hormone insulin.  There is no known way to prevent type 1 diabetes.

Type 2 diabetes

Type 2 diabetes, previously known as adult-onset diabetes, is a metabolic disease in which the body does not make enough insulin or use it effectively.  Type 2 diabetes can be prevented or delayed by maintaining a healthy weight and exercising regularly.

Gestational diabetes

Gestational diabetes occurs in pregnant women who have never had diabetes before but have higher than normal blood glucose levels during pregnancy.  Without intervention, women with gestational diabetes have a 40-60 percent chance of developing type 2 diabetes within 5-10 years.


Prediabetes is a condition that raises the risk of developing type 2 diabetes, heart disease and stroke.  People with prediabetes have blood glucose levels higher than normal but not high enough to be classified as diabetes.  Without intervention, about 25 percent of people with prediabetes will develop diabetes within 3-5 years.
