Pregnancy induced hypertension (PIH) is a condition of high blood pressure during pregnancy. Your blood pressure goes up, you retain water, and protein is found in your urine. It is also called toxemia or preeclampsia. The exact cause of PIH is unknown.

Who is at risk for Pregnancy Induced Hypertension (PIH)?

The following may increase the risk of developing PIH:

  • A first-time mom
  • Women whose sisters and mothers had PIH
  • Women carrying multiple babies; teenage mothers; and women older than age 40
  • Women who had high blood pressure or kidney disease prior to pregnancy

What are the symptoms of Pregnancy Induced Hypertension (PIH)?

Mild : high blood pressure, water retention, and protein in the urine.

Severe : headaches, blurred vision, inability to tolerate bright light, fatigue, nausea/vomiting, urinating small amounts, pain in the upper right abdomen, shortness of breath, and tendency to bruise easily. Contact your doctor immediately if you experience blurred vision, severe headaches, abdominal pain, and/or urinating very infrequently .

How do I know if I have Pregnancy Induced Hypertension (PIH)?

At each prenatal checkup your healthcare provider will check your blood pressure, urine levels, and may order blood tests which may show if you have hypertension.

Your physician may also perform other tests that include: checking kidney and blood-clotting functions; ultrasound scan to check your baby's growth; and Doppler scan to measure the efficiency of blood flow to the placenta.

How is Pregnancy Induced Hypertension (PIH) treated?

Treatment depends on how close you are to your due date. If you are close to your due date, and the baby is developed enough, your health care provider will probably want to deliver your baby as soon as possible.

If you have mild hypertension and your baby has not reached full development, your doctor will probably recommend you do the following:

  • Rest, lying on your left side to take the weight of the baby off your major blood vessels.
  • Increase prenatal checkups.
  • Consume less salt.
  • Drink 8 glasses of water a day.

If you have severe hypertension, your doctor may try to treat you with blood pressure medication until you are far enough along to deliver safely.

How does Pregnancy Induced Hypertension (PIH) affect my baby?

Pregnancy induced hypertension (PIH) can prevent the placenta from getting enough blood. If the placenta doesn't get enough blood, your baby gets less oxygen and food. This can result in low birth weight.

Most women still can deliver a healthy baby if PIH is detected early and treated with regular prenatal care.

How can I prevent Pregnancy Induced Hypertension (PIH):

Currently, there is no sure way to prevent hypertension. Some contributing factors to high blood pressure can be controlled and some can't. Follow your doctor's instruction about diet and exercise.

  • Use little or no added salt in your meals.
  • Drink 6-8 glasses of water a day.
  • Don't eat a lot of fried foods and junk food.
  • Get enough rest
  • Exercise regularly
  • Elevate your feet several times during the day.
  • Avoid drinking alcohol.
  • Avoid beverages containing caffeine.
  • Your doctor may suggest you take prescribed medicine and additional supplements.
