Low Blood Pressure During Pregnancy

Low blood pressure in pregnancy

Low blood pressure is less worrying than high blood pressure, but to be accompanied by tiredness and dizziness, it’s a hassle for pregnant woman.

Contrary to what happens during high blood pressure, “the low blood pressure (below 9/6) is much less worrisome and doesn’t imply risk, if not due to illness or is caused by heavy bleeding,” said Lluis Cabero , director of the Department of Gynecology and Obstetrics Hospital Chiron of Barcelona.


Even though it’s not serious, low blood pressure is annoying for pregnant women, as it may be in the form of palpitations, dizziness or constant tiredness.

Principal causes:

Discarded diseases and bleeding, the main reasons for abnormally low blood pressure in early pregnancy are hormonal changes. “And another possible cause is that the appearance of the placenta lowers the resistance that control blood circulation and thus reduces stress,” says our advisor.


Later, during the third trimester of pregnancy, when the pregnant woman is in the supine position (lying on your back), her uterus can compress the blood vessels of the pelvis and thus reduce the flow of blood that must reach the heart. This is called supine low blood pressure and can be corrected by lying on your side.

What can be done:

It is important to flee from excess heat and avoid staying too long standing. Also avoid lying on your back at the end of pregnancy. And women should stay hydrated, drinking enough water (at least two liters per day). These are the most effective ways, since there’s no medicine for raising the blood pressure.
