Latent Autoimmune Diabetes of Adults is a condition that can happen in people with family histories of Type 1 or Type 2 Diabetes. Contrary to popular belief, some people with LADA have body mass indexes between 24 and 34.9. In other words, some people with LADA may be overweight or obese. LADA occurs in people age 20 and older. LADA is often mistaken for type 2 diabetes, mainly in people who are overweight or obese. People with LADA can use oral medication, though within between 3-15 years after diabetes diagnosis, they will need to inject insulin.
