Everything You Need to Know About MODY Diabetes

When most people think about diabetes, they only think of type 1 and type 2. However, there are less common forms of the disease that most people don’t recognize.

MODY (maturity-onset diabetes of the young) and LADA (latent autoimmune diabetes in adults) are two examples. While these forms of diabetes have some of the same features of type 1 and type 2, they each have their own set of symptoms and treatments that are different.

What is Maturity-Onset Diabetes of the Young (MODY)?

MODY typically presents itself in adolescents or young adults. It is caused by mutations, which are changes in genes. These changes will affect how your body handles insulin.

MODY is considered rare and is only seen in about five percent of people in the U.S. that have diabetes.


Generally, the symptoms of MODY are mild. They can vary and depend on which gene has mutated and caused MODY. Not only do the symptoms vary, but they can also show up gradually, which can make them hard to spot.

Some of the symptoms that you may start to notice are similar to the more common types of diabetes:

  • Thirst
  • Urinating often
  • Blurry vision
  • Frequent infections


A simple blood sugar test can show that you have diabetes, however a doctor may become suspicious that it could be MODY if you are suffering from some of the following:

  • Diagnosed with diabetes in adolescence or early adulthood
  • History of diabetes in your family
  • Don’t have typical diabetes features like obesity or high blood pressure

If your doctor is worried about MODY, they may suggest a genetic test to confirm whether or not you do, in fact, have MODY..


Treatment options can vary depending on the gene that is mutated. The most common form of treatment for MODY is a type of oral diabetes drug called sulfonylureas.

Depending on the type of MODY you have, your doctor may prescribe injections of insulin. However, some people are able to manage their condition with simple lifestyle changes.
