Type 1 Diabetes
Type 1 diabetes is an autoimmune condition. The immune system attacks the cells in the pancreas that make insulin. People with this type usually need insulin treatment every day.
Type 2 Diabetes
Type 2 diabetes is the most common type. It usually develops when the body becomes resistant to insulin or when the body does not make enough insulin. Lifestyle habits can affect the risk of this type.
Gestational Diabetes
Gestational diabetes develops during pregnancy. It often goes away after birth, but it can increase the risk of type 2 diabetes later in life.
