Diabetes Types – A Guide to Type 1, Type 2 & Type 3 Diabetes

There are three diabetes types that go by the name type 1, type 2 and type 3. Each can have serious and even life-threatening consequences. This guide shares information about three diabetes types to help you better understand this condition called diabetes.

"An estimated 23.6 million people in the United States—7.8 percent of the population—have diabetes, a serious, lifelong condition. Of those, 17.9 million have been diagnosed, and 5.7 million have not yet been diagnosed".(1)

Of the diabetes types, most people are familiar with type 1 and type 2. These types of diabetes result due to issues with insulin production within the pancreas or insulin uptake by the body cells. Type 3 diabetes is connected to newly discovered insulin production in the brain.

In type 1 diabetes the body does not produce insulin due to a problem with the beta cells of the pancreas. Because type 1 diabetes can be diagnosed in children and young adults it is still commonly referred to as juvenile diabetes.

A person with type 1 diabetes cannot control their blood sugar level without daily insulin supplementation. Insulin can be administered as an injection under the skin or through an insulin pump.

Type 1diabetes and type 2 diabetes have similar symptoms including excessive thirst, more frequent urination, increased hunger, unexplained weight loss, chronic fatigue and possibly blurred vision. However, type 2 diabetes differs from type 1 as far as cause and treatment.

Type 2 diabetes is the most common of the diabetes types and develops slowly over time as a person’s body cells build a resistance to insulin. This resistance makes it difficult for insulin to move sugar out of the blood and this can lead to chronically high blood sugar levels.

Patients with type 2 diabetes do not typically require insulin treatment and can often control their disease with proper changes to their diet and exercise routine along with weight loss if necessary.

Type 3 diabetes was first recognized in 2005 after scientists discovered that insulin is also produced within the brain. This condition is being looked at closely due to its apparent link to degeneration of brain cells, which is an early symptom of Alzheimer’s

The abnormalities seen in type 3 diabetes do not correspond directly to type 1 and type 2 diabetes; instead they reflect a more complex disease that has its origin in the central nervous system.

Treatment varies among the three diabetes types and a definitive diagnosis must be made by your doctor. Most experts agree that a healthy diet, weight control and regular exercise can benefit any diabetic patient.
