There are two types of diabetes. Type 1 diabetes develops when the body’s immune system attacks and destroys pancreatic beta cells, the only cells in the body that make insulin. Insulin is a hormone that regulates blood sugar. People with type 1 diabetes, who comprise 10 percent of diabetes cases, develop it as children and must have insulin delivered by injection or a pump. Type 2 diabetes usually begins with insulin resistance, when cells do not use insulin properly. As the need for insulin rises, the pancreas gradually loses its ability to produce it. It is controlled by insulin and drugs, as well as diet and exercise.
Diabetes is irreversible once it occurs. However, it can be delayed or avoided with a combination of good health habits. Those who exercise, have a healthy diet, drink moderately and maintain a normal weight have an 89 percent lower incidence of diabetes.
