High Blood Pressure During Pregnancy
Blood pressure is the force at which blood flows through the large blood vessels from the heart. Normal blood pressure is important for good health. It helps your blood vessels, heart, and other organs work properly.
In some people, their blood pressure is too high. This is called hypertension.High blood pressure that starts in pregnancy is called gestational hypertension. No one knows what causes it. Many women with gestational hypertension have not had high blood pressure before. High blood pressure often shows up around the 20th week of pregnancy and usually goes back to normal by the 12th week after you give birth.
Why Blood Pressure is Important
Normal blood pressure is an important part of a healthy pregnancy. Blood pressure affects the amount of blood that goes through the placenta to your baby. The placenta is special tissue that grows in your womb when you are pregnant. It gives your baby the right amount of oxygen and nutrients for normal growth through the umbilical cord.
Most women with high blood pressure during pregnancy have healthy babies. But they do have a higher risk of certain problems. These range from mild to severe and can affect both the mother and her baby. High blood pressure can harm the mother’s heart, kidneys, and other organs. For the baby, it can cause low birth weight and early delivery.
Hypertension usually has no symptoms. The only way it can be found is through a blood pressure test. Make sure to have regular visits to your healthcare provider for prenatal care. It’s important to find high blood pressure early in pregnancy. If a test shows that you have high blood pressure, you and your baby will need special attention. If you have high blood pressure, you will also have your blood tested for a certain protein. This is to make sure you don’t have a more serious condition called preeclampsia.
Who is at Risk?
Some people are more likely to get gestational hypertension. If you’re age 20 or younger, or age 35 or older, you have a higher risk. Being overweight at the start of your pregnancy puts you at risk. If this is your first pregnancy ever, you may be more likely to have gestational hypertension. Certain health conditions such as diabetes, kidney disease, or autoimmune diseases such as lupus and rheumatoid arthritis put you more at risk. Being pregnant with more than one baby can make it more likely. And if you’ve had high blood pressure during other pregnancies, you’re more likely to have it again.
Treatment of gestational hypertension depends on certain factors, including how high your blood pressure is, what week of pregnancy you are in, and how healthy your baby is.
If you have mildly high blood pressure, your healthcare provider may prescribe bed rest and frequent prenatal visits. Bed rest helps lower blood pressure and increases blood flow through the placenta. Lying on your left side can help even more.
If you have severely high blood pressure, you may need to stay in the hospital so you and your baby can be watched.
In some cases, induction of labor or a cesarean delivery may be needed to protect the health of your baby and you. Your healthcare provider will tell you about the best options for you.
Things to Remember

- Start prenatal care visits to your healthcare provider early in your pregnancy.

It can be stressful to find out you have gestational hypertension. But with care and attention you can have a healthy pregnancy and a healthy baby.
