Risk factors for type 1 diabetes
Although the exact cause of type 1 diabetes is unknown, family history may play a role. The risk of developing type 1 diabetes increases if a parent or sibling has type 1 diabetes.
Risk factors for pre-diabetes and type 2 diabetes
Researchers don't fully understand what causes people to develop pre-diabetes and type 2 diabetes, but it is clear that certain factors increase the risk including:
- Physical inactivity
- Family history: A parent or sibling has type 2 diabetes.
- Race: If you are African-American, Hispanic, American Indian and Asian-American.
- Age: Risk increases as a person ages, especially after age 45. But type 2 diabetes is increasing dramatically among children, adolescents and younger adults.
- Gestational diabetes
Risk factors for gestational diabetes
Any pregnant woman can develop gestational diabetes, but some women are at greater risk than are others. Risk factors for gestational diabetes include:
- Age: Women older than age 25.
- Family or personal history: Pre-diabetes or if a close family member has type 2 diabetes, gestational diabetes during a previous pregnancy, delivered a very large baby weighing more than 9 pounds at birth.
- Weight: Being overweight before pregnancy.
- Race: If you are African-American, Hispanic, American Indian or Asian-American.
The American Diabetes Association website offers a Diabetes Risk Test to help determine if you should talk to a doctor about diabetes.
