Causes
- Type 1 diabetes is caused by an autoimmune reaction, although the exact reason why this happens is unknown. Genetics and environmental factors are believed to play a role.
- Type 2 diabetes is caused by a combination of factors, including genetics and lifestyle choices. Being overweight or obese, having a family history of diabetes, and being inactive are all risk factors for type 2 diabetes.
- Gestational diabetes is caused by hormones produced during pregnancy that can make it harder for your body to use insulin.
