High Blood Pressure During Pregnancy

Treatment depends on the type of high blood pressure you have and how serious it is.
If you have high blood pressure, your health care provider may give you medicine to treat it and also to lessen risks to you and the baby.
If you have very bad high blood pressure, you may need to stay in the hospital for treatment.
If your condition gets worse, your baby may need to be born early.
If you were taking medicine for your blood pressure before you got pregnant, talk with your provider. You may need to change the medicine during pregnancy if it is not safe for your baby.
