high blood pressure 36 weeks pregnant And the reasons for its rise


high blood pressure 36 weeks pregnant، One of the great pathologies that still does not find a clear answer despite the constant efforts of researchers, is high blood pressure (hypertension) in pregnancy.

Despite having been described by Hippocrates many years ago, even today in this 21st century, he continues to take the lives of young women and their babies before or after they are born.

The mortality of the baby, premature babies or with low weight (delayed intrauterine growth, CIR) are the main complications. In the maternal mortality statistics, arterial hypertension (AHT) is among the first three causes.

Pregnant women with high blood pressure are predisposed to serious and life-threatening complications such as detachment of the placenta, clot formation throughout the body (thromboembolism), cerebral hemorrhage, failure of liver and kidney function.

The number of women who have hypertension in the course of pregnancy also called pre-eclampsia is around 10% to 20%. While 1 to 5% of pregnant women may have chronic or essential hypertension.


Blood pressure is the pressure at which the blood circulates through the arteries (TA) to carry oxygen and nutrients to all the organs of the body. Every time the heart contracts, it pumps blood to the arteries.

how is the arterial pressure measured?

Blood pressure is measured while the heart contracts (systolic pressure) and while the heart is relaxed between contractions (diastolic pressure). Blood pressure values ​​are expressed with two numbers, where the upper number represents the systolic pressure and the lower the diastolic pressure, for example 110/80.


When the pressure of the arteries gets too high, we talk about high blood pressure or hypertension. Up to eight percent of women suffer from hypertension during pregnancy. In adults, hypertension is defined as blood pressure:

Greater than or equal to 140 mm Hg systolic pressure.
Greater than or equal to 90 mm Hg diastolic pressure. (Between each beat, when the heart is at rest, the pressure drops, called diastolic pressure.)

how is the arterial pressure measured?

It is said that you have “hypertension” when you have taken your blood pressure several times when you are relaxed and the values ​​are high.

It is important to pay attention to personal blood pressure, because this condition at first does not cause symptoms, but can cause serious long-term complications: heart disease, kidney failure, diseases of the arteries and aneurysms.


An adequate measurement of blood pressure requires detailed attention. Blood pressure may rise in normal patients in the following circumstances:

Fear: Fear raises blood pressure, so the patient should be calm and relaxed.
Cold: Whenever possible, blood pressure should be taken in a warm environment.
Full bladder: This can cause the pressure to rise.
Exercise: It is important that you rest for 5 minutes before your blood pressure is measured.
Obesity: (Circumference in the middle of the arm greater than 29 cm). Overweight patients do not necessarily have high blood pressure, but small cuffs cause high readings.
The reading of abnormal high blood pressure should be repeated after 10 or 15 minutes when you are calm and comfortable.

Hypertension in pregnancy arises when blood pressure is above 140/90 mmHg, especially in women who never had an increase in blood pressure, being able to cause neck pain, abdominal pain, blurred vision and fluid retention with swelling of the body.

The causes of high blood pressure during pregnancy can be related to an unbalanced diet or malformation of the placenta. In addition to this, the woman is more at risk of having hypertension in pregnancy when she is pregnant for the first time, is over 35 years old, has obesity and / or is diabetic.

Normally, blood pressure usually falls during the first half of pregnancy, returning to normal or rising slightly in the second half of pregnancy, closer to delivery. For this reason, if the pregnant woman notes that she has high blood pressure, mainly after 20 weeks of pregnancy, she should go to the obstetrician immediately to be evaluated.

Hypertension in pregnancy- Symptoms and what to do
High blood pressure in pregnancy can be dangerous, since it can cause the development of preeclampsia, a serious complication that can cause abortion or fetal death, in case it is not adequately treated with medication or with a balanced diet. Know what preeclampsia is and how to identify it.

Symptoms of high blood pressure
Although it does not always cause symptoms, the signs that may indicate that the pressure is high during pregnancy are:

Blood pressure greater than 140/90 mmHg;
Constant headaches, especially in the neck;
Severe pain in the abdomen;
Blurred vision and sensitivity to light;
Swelling of the extremities of the body such as legs, feet or arms.

In the presence of symptoms of hypertension in pregnancy, it is recommended to consult the obstetrician as soon as possible to initiate the appropriate treatment and avoid serious complications.
How to lower the pressure in pregnancy

To treat high blood pressure during pregnancy, you should keep at rest, drink 2 to 3 liters of water daily and eat a balanced diet low in salt or industrialized foods such as sausages, canned goods, trinkets or chips.

In addition to this, other tips that help lower high blood pressure in pregnancy are: drink 1 glass of orange juice per day, practice light physical activity such as walking, yoga or water aerobics, for 2 to 3 times a week, and you should avoid drinking more than 1 cup of coffee per day.

However, in cases where high blood pressure does not decrease with this care, the obstetrician may recommend treatment with medications for hypertension. Already in the most serious cases, the pregnant woman may have to stop working or stay hospitalized to prevent the development of eclampsia.

Risks of high pressure in pregnancy
Hypertension in pregnancy increases the risk of preeclampsia, a disease that usually appears after the 20th week of pregnancy and, when left untreated, can progress to eclampsia, causing seizures and even the death of the mother and baby.

If blood pressure can not be lowered, even if the medications prescribed by the obstetrician are being ingested, delivery should be induced to avoid the risk of death.
Diet to lower the pressure

The diet and foods to lower high blood pressure in pregnancy should be low in salt and rich in folic acid, as it has vasodilatory action, helping to lower blood pressure. In addition to this, water consumption should be high and diuretic foods, to avoid fluid retention and relieve pressure within the blood vessels.
