The 4 Major Types of Diabetes

Below you’ll learn about the 4 types of diabetes: Type 1, Type 2, Type 1.5 and Type 3.

What is Type 1 Diabetes?

Type 1 Diabetes is known as Juvenile Diabetes (Insulin-dependant diabetes mellitus or IDDM). This type is found in children and young adults. People get Type 1 Diabetes due to an autoimmune disease that destroys the insulin producing cells of the pancreas. These people are insulin dependant requiring lifelong injections of insulin.

What is Type 2 Diabetes?

Type 2 Diabetes is called Adult onset; we also like to call this “insulin resistant diabetes”. People are usually diagnosed due to poor diet and lifestyle choices for many years. The number of people with prediabetes and Type 2 diabetes is growing like crazy in the U.S.

Diabetes in the United States

According to Centers for Disease Control and Prevention (CDC), “More than 29 million people in the United States have diabetes, up from the previous estimate of 26 million in 2010, according to a report released today by the Centers for Disease Control and Prevention. One in four people with diabetes doesn’t know he or she has it. Another 86 million adults – more than one in three U.S. adults – have prediabetes, where their blood sugar levels are higher than normal but not high enough to be classified as type 2 diabetes.”

What is Type 1.5 Diabetes?

Type 1.5 Diabetes is called Latent Autoimmune Diabetes in Adults. It’s similar to the type 1 found in children, but this type is found in adults. Type 1.5 accounts for 15-20% of diabetes cases.

Misconceptions of Type 1.5

Type 1.5 Diabetes is commonly misdiagnosed as Type 2 insulin resistant diabetes, but it still differs. In results of misdiagnoses, the medications commonly prescribed for type 2 DO NOT WORK or work for a very short time, then blood sugar levels continue to creep upwards. Often these people will not be overweight and will look healthy, but will have destruction of the pancreas due to an autoimmune reaction. This results in an inadequate amount of insulin being produced causing high blood sugar levels.

  • Management of Type 1.5 diabetes must revolve around controlling the autoimmune attack, not just prescribing insulin. Similar to the article on autoimmune thyroid disease called Hashimoto’s, simply taking thyroid replacement medications does nothing to address the autoimmune attack on the thyroid gland itself.
  • A specific blood test must be done to confirm Type 1.5 diabetes. The test is called Glutamic Acid Decarboxylase 65 (GAD 65) antibody test and insulin + islet cell antigen test. This test is available at the Bay Area Health and Wellness Center.

Type 3 Diabetes and the brain

*Did you know the brain can become insulin resistant and lose the capacity to use glucose (sugar) as energy, which results in decreased brain function?

Dr. David Perlmutter, MD, author of Grain Brain, discusses how toxic carbs and sugar are for the brain. To read more about his specific take on this subject, you can read his article called, “Blood Sugar and Your Brain”.

Bay Area Health and Wellness Center’s take on Type 3 Diabetes

Dr. Ernesto Medina, DC says, “The brain can become insulin resistant even before the body does, because the brain is even more sensitive to high blood sugar levels than the body is”. He is actively reading and researching new health and wellness studies.  A recent research summary in Life Extension Magazine summarized these exact findings.
