• Gestational diabetes is a temporary condition that happens during pregnancy. People who have gestational diabetes are at higher risk of developing type 2 diabetes later.

 

  • Latent autoimmune diabetes in adults (LADA) may actually be type 1 diabetes but is diagnosed in older people. It tends to come on more slowly and may be misdiagnosed as type 2 diabetes. People with LADA can sometimes go for a while without needing to take insulin, but eventually, they will need insulin just like people with type 1 diabetes. Many people with LADA use the same treatments and technologies as people with type 1 diabetes.

 

  • Maturity-onset diabetes of the young (MODY) is a group of genetic conditions caused by a change in a single gene. MODY usually starts before age 30. Depending on which gene is impacted, the diabetes may be quite different. Some types of MODY are very mild and don’t need treatment. Others can be misdiagnosed as type 1 diabetes, but tablets work better than insulin for the people with these types. In other forms, people can’t make enough insulin and need treatments like people with type 1 diabetes. MODY is often misdiagnosed as type 1 or type 2 diabetes, but a strong family history of diabetes and the absence of autoantibodies are key indicators.

 

  • Type 3c diabetes happens when people’s pancreas is damaged or removed, reducing or removing their ability to make insulin. People with type 3c diabetes are typically treated as though they have type 1 diabetes and use the same treatments and technologies.
