What is high blood pressure during pregnancy?
Your heartbeat creates a force called blood pressure that pushes your blood against the walls of your arteries while carrying oxygen to different parts of your body. High blood pressure (or hypertension) is a condition where too much force is generated against the blood vessels in your body.
High blood pressure during pregnancy can also lead to a situation where your doctor must induce labor early. If this happens, your baby could be born prematurely.
High blood pressure during pregnancy can also lead to other complications, including:
- Restricted growth of your fetus caused by a decreased flow of nutrients
- The placenta detaching from the wall of your uterus
- A higher chance of having a cesarean birth (also called a C-section)
Signs of high blood pressure during pregnancy
There are several different high blood pressure types that women experience while pregnant, including:
Women with chronic hypertension experienced high blood pressure before becoming pregnant or developed it before the 20th week of their pregnancy. Chronic hypertension can lead to the development of preeclampsia in your second or third trimester.
Gestational hypertension occurs only while a woman is pregnant. Doctors typically diagnose the condition after the 20th week of pregnancy or when the mother is close to delivering her baby. This form of high blood pressure during pregnancy usually goes away after the birth of your baby.
Like gestational hypertension, preeclampsia develops after the 20th week of pregnancy. Preeclampsia differs from gestational hypertension in that it comes on quickly. Pregnant women with this form of high blood pressure have detectable protein in their urine and often end up with other health complications.
Pregnant women with preeclampsia often experience the following symptoms:
- Persistent headache
- Pain in the upper stomach
- Swelling in the hands and face
- Sudden weight gain
- Problems breathing
- Vision problems like blurry vision or changes in eyesight
You can experience preeclampsia while you are pregnant and not have any symptoms. That’s why you need to have regular checkups during your pregnancy so your doctor can monitor your blood pressure.
In rare cases, women can experience postpartum preeclampsia and develop preeclampsia after giving birth. Postpartum preeclampsia can occur in women who did not experience preeclampsia while they were pregnant. Most cases of postpartum preeclampsia are diagnosed within 48 hours of delivery. However, the condition can take up to six weeks to develop.
Causes of high blood pressure during pregnancy
You may be more at risk of developing high blood pressure during your pregnancy if you have one or more of the following risk factors:
- You are experiencing your first pregnancy
- You had chronic kidney disease or high blood pressure before becoming pregnant
- You are over the age of 40
- You have diabetes
- You experienced high blood pressure or preeclampsia during a previous pregnancy
- You are African American
- You are carrying more than one baby
- You have a family history of pregnant women who experienced preeclampsia
- You have lupus or thrombophilia (a disorder that can cause blood clots)
- You became pregnant through in vitro fertilization, donor insemination, or egg donation
When to see the doctor for high blood pressure during pregnancy
Pregnant women should have regular prenatal visits with their doctor to monitor their and their baby’s health. You should let your doctor know about any health problems you experience, especially if you have symptoms of high blood pressure.
Early treatment for high blood pressure while pregnant can reduce your chances of developing more severe health complications. Your doctor can also make other recommendations to help you stay healthy during your pregnancy.
Diagnosing high blood pressure during pregnancy
Your doctor will check your blood pressure during prenatal visits. If you record a high blood pressure, which is 140/90 or higher, your doctor will likely order additional tests, especially if you are in the 20th week of your pregnancy or later.
These tests might include blood tests and urine tests to check for any protein in your urine, an indicator of preeclampsia.
Treatments for high blood pressure during pregnancy
If you have preeclampsia, the condition usually clears up once you deliver your baby. For milder cases of gestational hypertension or preeclampsia, your doctor may wish to have you monitored in an outpatient facility or a hospital. Your doctor may also ask you to track your baby’s movements via a kick count and measure your blood pressure at home.
If you experience high blood pressure during pregnancy, you will need to visit your doctor at least once per week and, in some cases, twice per week until you reach the 37th week of your pregnancy. At that point, your doctor may recommend inducing delivery. They may also ask you to have your baby earlier than 37 weeks if they feel that your baby’s health may be at risk.
If you have a more severe case of preeclampsia, you will likely be admitted to a hospital. Your doctor may encourage inducing labor at 34 weeks. They may also administer medications intended to lower your blood pressure and reduce your chances of having a seizure.

Top How Does High Blood Pressure Affect Pregnancy Related Articles
What Does it Mean When the Bottom Number of Your Blood Pressure is Over 100?Diastolic blood pressure (DBP) is the pressure exerted on the walls of the arteries when the heart muscle relaxes between beats. When the bottom number of blood pressure (diastole) is over 100 mmHg, it may be called diastolic hypertension (DHT). Diastolic blood pressure means the blood pressure reading during the phase when your heart relaxes (diastole). Force of the blood against the walls of the arteries (the blood vessels carrying blood from the heart to other sites) in the body is called blood pressure. The heart pumps the blood into the arteries as it contracts (systole).
Can Blood Pressure Spike For No Reason?It is normal for your blood pressure to rise and fall throughout the day. Your blood pressure can fluctuate at any time due to various reasons.
Ectopic Pregnancy (Tubal Pregnancy)
An ectopic pregnancy is a pregnancy located outside the inner lining of the uterus. The majority of ectopic pregnancies occur in the Fallopian tube. Signs and symptoms of an ectopic pregnancy may include abdominal pain, lack of menstrual period (amenorrhea), vaginal bleeding, fainting, dizziness, and low blood pressure.
Treatment options for an ectopic pregnancy include observation, medication, or surgery.

High Blood Pressure (Hypertension)
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.
Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.
The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.
If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.

How Can I Bring My Blood Pressure Down Immediately?High blood pressure is diagnosed when the force of your blood pressing against the artery wall is too high for an extended period of time. Bring your blood pressure down immediately by taking a hot shower or bath and practicing deep breathing and relaxation techniques.
How Do You Check Your Blood Pressure With Fingers?Most doctors recommend the use of a blood pressure machine to check blood pressure. An individual may check heart rate with their fingers, but not blood pressure.
Is A Manual Blood Pressure More Accurate?Manual blood pressure gives accurate results when used correctly by a trained person. However, manual blood pressure measurement is not the recommended type of blood pressure monitoring for home use because it requires some training.
What Does It Mean When the Diastolic Number is High?A high diastolic reading (equal to or greater than 120 mmHg) is linked to a higher risk of heart disease, abdominal aortic aneurysm, and other cardiovascular problems.
What Time of Day Is Blood Pressure Highest?Your blood pressure follows a pattern, rising a while before you wake up. It is the highest at midday and tends to drop in the evening or late afternoon.
