Key Takeaways

  • LADA is type 1 diabetes, but is often misdiagnosed as type 2 diabetes.
  • If you are following your diabetes treatment plan but it is not working and you're not reaching your blood glucose (blood sugar) targets, talk with your doctor about being tested for type 1 diabetes.
  • The only way to find out if you have LADA is by talking to your doctor and getting tested to be sure what type of diabetes you have.

What is latent autoimmune diabetes in adults (LADA)?

LADA is type 1 diabetes, but when you first develop it, it can be mistaken for type 2 diabetes. Type 1 diabetes most often develops in young people when your immune system mistakenly destroys the beta cells in your pancreas that make insulin. This usually progresses quickly, but with LADA, the process happens slowly and starts in adults 35 years old or older, which is why it can be misdiagnosed as type 2 diabetes. Over time (a few months or even years) the body slowly loses the ability to make insulin and you eventually need to take insulin to live.

How is LADA diagnosed?

In addition to standard tests to diagnose diabetes, your doctor will likely request the following:

  • Testing for diabetes antibodies: This will test for antibodies that can lead to type 1 diabetes. If the antibodies are present, it could mean that your immune system is attacking the cells that make insulin.
  • C-peptide test: This will test for how much insulin your body makes.

Hear From Others

You are not alone in the struggle for a correct diagnosis. Here are the stories of others who were incorrectly diagnosed before learning they live with LADA.

Signs and Symptoms of LADA

Early recognition is key to helping manage blood glucose levels and prevent or delay complications. Because LADA is type 1 diabetes, the symptoms are are the same. Learn about the symptoms of type 1 diabetes. 

What are the risk factors for developing LADA?

In addition to the autoimmune process, genetics play a role in developing LADA. You might be at higher risk due to: 

  • Family members living with type 1 diabetes 
  • Having other autoimmune conditions 
  • Exposure to certain environmental factors 
  • Having inflammation
