Pregnancies with a greater chance of complications are called "high-risk." But this doesn't mean there will be problems. The following factors may increase the risk of problems during pregnancy:
- Very young age or older than 35
- Overweight or underweight
- Problems in previous pregnancy
- Health conditions you have before you become pregnant, such as high blood pressure, diabetes, autoimmune disorders, cancer, and HIV
- Pregnancy with twins or other multiples
Health problems also may develop during a pregnancy that make it high-risk, such as gestational diabetes or preeclampsia. See Pregnancy complications to learn more.
Women with high-risk pregnancies need prenatal care more often and sometimes from a specially trained doctor. A maternal-fetal medicine specialist is a medical doctor that cares for high-risk pregnancies.
