Pregnancy-induced Hypertension | Symptoms


What are the symptoms of PIH?

If you have any of the following symptoms of PIH, call your doctor right away:

  • Severe headaches
  • Vomiting blood
  • Excessive swelling of the feet and hands
  • Smaller amounts of urine or no urine
  • Blood in your urine
  • Rapid heartbeat
  • Dizziness
  • Excessive nausea
  • Ringing or buzzing sound in ears
  • Excessive vomiting
  • Drowsiness
  • Fever
  • Double vision
  • Blurred vision
  • Sudden blindness
  • Pain in the abdomen (tummy)

Does high blood pressure mean I have PIH?

Not necessarily. If your doctor sees that your blood pressure is high, he or she will watch you closely for changes that could mean you have PIH. In addition to high blood pressure, women who have PIH also have excessive swelling. They may also have protein in their urine. Many women who have high blood pressure during pregnancy don't have protein in their urine or extreme swelling, and don't get PIH.

Does swelling mean I have PIH?

Swelling alone doesn't necessarily mean you have PIH. Some swelling is normal during pregnancy. For example, your rings or shoes might become too tight. Swelling is more serious if it doesn't go away after resting, if it's very obvious in your face and hands or if it's a rapid weight gain of more than 5 pounds in a week.
