Risk factors
By Mayo Clinic staffAny woman can develop gestational diabetes, but some women are at greater risk. Risk factors for gestational diabetes include:
- Being older than age 25. Women older than age 25 are more likely to develop gestational diabetes.
- Family or personal health history. Your risk of developing gestational diabetes increases if you have prediabetes — a precursor to type 2 diabetes — or if a close family member, such as a parent or sibling, has type 2 diabetes. You're also more likely to develop gestational diabetes if you had it during a previous pregnancy, if you delivered a baby who weighed more than 9 pounds, or if you had an unexplained stillbirth.
- Being overweight. You're more likely to develop gestational diabetes if you're significantly overweight with a body mass index (BMI) of 30 or higher.
- Race. For reasons that aren't clear, women who are black, Hispanic, American Indian or Asian are more likely to develop gestational diabetes.
