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.
