It's common to develop hypertension, or high blood pressure, during pregnancy. Up to 10% of pregnant women do. The risk of developing hypertension in a twin pregnancy is approximately 2.5 times greater in twin pregnancy compared to a singleton pregnancy. Usually it starts after you've been pregnant for about 20 weeks. With good care, it won't harm you or your twins and will go away after you deliver. But you're more likely to develop hypertension again when you're older. If you get hypertension after mid-pregnancy, and you have protein in your urine, you may have a more complex problem called preeclampsia.
Call Doctor If:
- Get early and regular prenatal care. Your doctor can monitor your blood pressure and urine protein carefully to detect any problem early.
- Don't smoke or drink alcohol.
- Eat healthy, regular meals and take a prenatal vitamin.
