There's no known way to prevent preeclampsia. Eating less salt or changing your activities during pregnancy doesn't reduce the risk. The best way to take care of yourself — and your baby — is to seek early and regular prenatal care. If preeclampsia is detected early, you and your doctor can work together to prevent complications.

There's some evidence that taking certain vitamins, such as vitamin D, may lower the risk of preeclampsia. Ask your doctor what he or she recommends. Don't take anything during pregnancy without your doctor's approval.
