Risk Factors

Pre-eclampsia is more common in women aged 40 years and older.

Other factors that may raise your chance are:

  • Pre-eclampsia in a prior pregnancy
  • Antiphospholipid antibody syndrome
  • Diabetes
  • Carrying multiple babies such as twins
  • First pregnancy
  • Chronic high blood pressure
  • Overweight or obese


You may not have symptoms. If you do have symptoms, you may have:

  • Rapid weight gain
  • Swelling of the hands and face
  • Headaches
  • Problems seeing
  • Nausea and vomiting
  • Upper belly pain
  • Overactive reflexes
  • Chest pain
  • Problems breathing


The doctor will ask about your symptoms and health history. A physical exam will be done. Preeclampsia is diagnosed if you have high blood pressure.

You may also have:

  • Urine tests to look for high protein levels
  • Blood tests


Early treatment can help prevent eclampsia, which is seizures caused by severe pre-eclampsia.

The only way to cure this condition is to deliver the baby. The decision to do so depends on many things, such as:

  • How many weeks along you are in your pregnancy
  • The health of you and your baby
  • Severity of the pre-eclampsia
  • Risk of other problems

Labor may happen on its own or it may be started by your doctor. If there are life-threatening problems for either you or your baby, a cesarean section may be done. During labor, you may need medicine to control your blood pressure and prevent seizures.

Mild pre-eclampsia can often be managed with rest and medicine if the baby is close to term. Your doctor may advise medicines to:

  • Lower your blood pressure
  • Lower the risk of seizures
  • Help the fetus’ lungs develop if there is a chance it may be born too early

If you live close to the hospital, your doctor may advise that you rest at home in a quiet setting. At home, you may need to:

  • Taking frequent blood pressure readings
  • Have help to make meals, do housework, and care for other children you may have
  • Check your baby's health, which may mean:
    • Watching for fetal movement
    • Tracking kick counts
    • Follow-up visits to monitor conditions inside the uterus

If pre-eclampsia is moderate or your home setting is not restful, the doctor may admit you to the hospital. This may mean:

  • Lowering your blood pressure with medicine
  • Taking medicines to prevent eclampsia
  • Monitoring your baby's health
  • Making sure you get enough rest


If you have had pre-eclampsia in the past, ask your doctor whether you should take aspirin. It has been shown to prevent this health problem in women who are at risk.
