Hypertension During Pregnancy
WHAT YOU NEED TO KNOW:
What do I need to know about hypertension during pregnancy?
Hypertension is high blood pressure (BP). Your BP is the force of your blood moving against the walls of your arteries. Normal BP is less than 120/80. Hypertension in pregnancy is defined as a BP of 140/90 or greater. It is important to get screened and treated for hypertension during pregnancy. This can prevent problems with you or your baby. Hypertension during pregnancy can be defined as any of the following:
- Chronic hypertension means you have high BP before week 20 of your pregnancy. Hypertension may have been diagnosed before you became pregnant.
- Gestational hypertension means you develop high BP between week 20 and 37 of your pregnancy. It may also develop after week 37 of your pregnancy.
- Preeclampsia is a condition that can develop during week 20 of your pregnancy, or later. Your BP may be 160/100 or higher. You may also have protein in your urine. Preeclampsia can cause mild to life-threatening health problems for you and your unborn baby. You are at risk for developing preeclampsia if you have chronic or gestational hypertension.
Why is it important to treat hypertension during pregnancy?

- Damage to organs such as your kidneys
- Life-threatening bleeding or seizures
- Preterm labor, miscarriage, or stillbirth
- Placenta separation from the wall of your uterus
- A baby that is born small for his or her gestational age
- Diabetes during pregnancy

How is hypertension during pregnancy diagnosed?
Your healthcare provider will ask about your symptoms. He or she will check your BP. Hypertension is diagnosed when you have 2 BP readings of 140/90 or higher. The readings should be taken at least 4 hours apart. You may need blood or urine tests to check for problems caused by hypertension.
How is hypertension during pregnancy treated?
Your healthcare provider will decide if you need medicine to lower your BP. If you already take medicine for high BP, your medicine may be changed. Instead, the dose of your BP medicine may be increased. You will need frequent ultrasounds. An ultrasound checks your baby's growth and makes sure your baby is healthy.
What can I do to manage hypertension during pregnancy?
- Check your BP at home. Sit and rest for 5 minutes before you take your BP. Extend your arm and support it on a flat surface. Your arm should be at the same level as your heart. Follow the directions that came with your BP monitor. Take your BP at least twice a day at the same times each day, such as morning and evening. Take at least 2 BP readings each time. Keep a record of your BP readings and bring it to your follow-up visits. Ask your healthcare provider what your BP should be.
- Do not smoke or drink alcohol during your pregnancy. Alcohol, nicotine, and other chemicals in cigarettes and cigars, can damage your blood vessels and increase your BP. They can also harm your baby. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
- Eat healthy foods. Healthy foods can help control your BP. Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. Ask if you need to be on a special diet.
- Exercise as directed. Exercise can help lower your BP. Ask your healthcare provider how much exercise you need and which exercise is right for you.
