High Blood Pressure in Pregnancy

Arterial hypertension is considered to be pressure above 140/90 mm Hg. There may be a threat to the fetus with such indicators. There is strong vasoconstriction and blood circulation is disturbed. There is a lack of oxygen and nutrients that should be supplied to the child. This slows down its growth and development.

Blood pressure is one of the most important indicators of the circulatory system. It functions with a double load during pregnancy. The pressure rises with increased blood flow as the fetus grows.

When Does High Blood Pressure Start in Pregnancy?

High blood pressure is most evident at the end of the second and beginning of the third trimester. It begins to disturb a woman in a position with the growth of the uterus and an increase in blood flow. Pressure can accompany a woman for the entire period of gestation with multiple pregnancies, overweight and hereditary diseases.


Pressure problems may appear at the 18th week. Then this symptom occurs in the 26th-27th weeks. The volume of blood increases significantly, the uterus grows, and there is a huge load on the cardiovascular system at these times. High blood pressure should not last long. An increase in pressure at the beginning of pregnancy is an abnormal phenomenon that requires treatment.

High Blood Pressure weeks in pregnancy

When will it end?

The symptom should disappear after the 27th week of pregnancy. This occurs after the adaptation of the circulatory system to high loads. A single manifestation of high blood pressure cannot be considered hypertension. The symptoms end when the uteroplacental circulation is normalized. Hypertension can remain even after childbirth in case of health problems.

How High Blood Pressure Feels during Pregnancy?

High blood pressure may not be accompanied by additional sensations. It is discovered by chance during a visit to the gynecologist. There will be an increased indicator on the tonometer, and the woman may not complain at all about the symptoms. Sensations are most often more vivid: headaches, pulsation of the temples, shortness of breath, swelling, etc.


The manifestation of high blood pressure in an acute form is accompanied by sharp and severe headaches, a feeling of pressure in the heart, and muscle weakness. There is tinnitus, dizziness, and sometimes nausea. There is severe shortness of breath and swelling.


The symptom is manifested to a mild degree by a feeling of constriction in the head, weakness, and increased fatigue. The woman does not complain of severe headaches or other discomforts. High pressure is determined only by a tonometer.

Additional symptoms with high blood pressure may indicate the presence of serious diseases.

Prevention methods

It is difficult to prevent the appearance of high blood pressure with a hereditary predisposition during pregnancy. It is necessary to constantly monitor the indicators and regulate the symptoms with the help of therapy. Maintaining a healthy lifestyle is the most effective among the main preventive measure. Prevention methods:

Compliance with sleep patterns

Regular quality sleep will help normalize pressure surges. Go to bed on time. Don’t overwork yourself and don’t skip sleep. Sleep at least 8 hours a day and during pregnancy at least 10 hours. Wakefulness should be replaced by rest. Useful daytime sleep. Follow the regime to maintain the balance of the cardiovascular system.

Weight correction

Being overweight is the source of many problems, including pressure. Adjust your weight before pregnancy and during this position. Get rid of malnutrition, the consumption of harmful foods, and large amounts of food. Go in for sports. There will be fewer problems during gestation with the correct weight.

Elimination of stress

The calmer you are, the less your blood pressure will jump. Do not enter into meaningless conflicts, bypass negative people, and change hard work to a more neutral one. Don’t worry about trifles. Engage in psychotherapy and meditation if necessary.

Why High Blood Pressure Occurs in Pregnancy?

The volume of circulating blood increases significantly during the period of gestation, and an additional network of vessels, the uteroplacental circle, is formed. This leads to high stress on the cardiovascular system. The pressure constricts the blood vessels and causes untidy sensations.

Hereditary predisposition and the presence of chronic diseases are common causes of high blood pressure in pregnant women. It can be adrenal dysfunction, thyroid gland dysfunction, or diabetes mellitus.

Another cause of hypertension is an increase in intra-abdominal pressure. It is caused by an increase in the uterus and displacement of the internal organs. Most of the consequences are with a shift of the heart, the work of which is difficult. The heart rate increases. High production of sex hormones is bad for the condition of the walls of blood vessels. They thin out and expand a lot. This increases the risk of developing circulatory problems.


There is a narrow list of drugs allowed during pregnancy. If you have a serious problem with high blood pressure, you should consult a doctor. You cannot take medication on your own. Among non-pharmacological agents, there are many effective ones, but they will not help if the cause of pressure is hereditary or chronic. Consider the most effective remedies for high blood pressure during pregnancy:

Bed rest

Strict bed rest is prescribed for the long-term persistence of symptoms of high blood pressure. Sometimes hospitalization may be advised to maintain the pregnancy. Such measures are taken in extreme cases. Rest and calmness are the best ways to normalize blood pressure without medication.


The diet is prescribed to correct nutrition for high blood pressure therapy. Completely excluded from the diet: spicy, salty, sweet, fatty, caffeine and chocolate. These are the main stimulants of a sharp jump in blood pressure. The drinking regimen and the amount of food consumed at one time are monitored.

Antihypertensive drugs

Pharmacological agents are prescribed for acute symptoms. Medicines are used when it is not possible to alleviate the situation of a pregnant woman by conservative methods. These should be calculated risks. Medications are taken strictly under medical supervision. You cannot use medicines for pressure without a prescription. This can be bad for pregnancy.


It is imperative to consult a doctor if signs of preeclampsia appear: sharp pains in the head, nausea, vomiting, and protein in the urine. This complication of pregnancy is extremely dangerous for both mother and child. There is a threat of miscarriage or fetal growth retardation.

It is necessary to call an ambulance in case of severe shortness of breath, swelling, pallor of the skin, or abdominal pain. A high-pressure surge can signal a premature pregnancy or miscarriage.

What Not to Do

Don’t put yourself at risk of complications from high blood pressure. It is necessary to exclude all factors provoking the symptom. For starters, don’t self-medicate. You should always consult with your doctor at your next appointment. Do not use what is currently in your first aid kit. High-pressure prohibitions:

Physical activity

Do not lift heavy, do not overwork, and take a break from yoga, gymnastics, or swimming. Stay at rest until symptoms subside.


It is strictly forbidden for high blood pressure. Even being in a stuffy room can trigger an attack of hypertension.

Drink coffee, cola, and strong tea

These drinks worsen the condition at high pressure, creating an additional load on the vessels. Their use should be completely excluded.
