What is the normal blood pressure during pregnancy?

During pregnancy, women will undergo many tests, including blood tests, urine tests, B-ultrasound, etc. These are all necessary tests for pregnant women. Pregnant women are very worried about whether their blood pressure is normal. When a pregnant woman becomes pregnant, there will be a deviation in her blood pressure, because her blood pressure may be high or low. The situation of each pregnant woman is different. As long as it is within a reasonable range, it is normal. Next, I will introduce to you the normal blood pressure values ​​for pregnant women during pregnancy.

After pregnancy, blood pressure will drop slightly. It is generally believed that if the systolic blood pressure is higher than 140 and/or the diastolic blood pressure is greater than 90, the possibility of gestational hypertension should be considered. Further examination and multiple measurements are required. If gestational hypertension is considered, pay attention to a low-salt diet and use drugs that dilate the arterioles when necessary.

Systemic arterial blood pressure is referred to as blood pressure (BP). Blood pressure is the pressure exerted on the blood vessel walls when blood flows in the blood vessels. It is the driving force that pushes blood to flow in the blood vessels. When the ventricles contract, blood flows from the ventricles into the arteries. At this time, the pressure of blood on the arteries is the highest, which is called systolic blood pressure (SBP). The ventricle relaxes, the elasticity of the arteries shrinks, and the blood continues to flow forward slowly, but the blood pressure drops. The pressure at this time is called diastolic blood pressure (DBP).

The human body's circulatory organs include the heart, blood vessels and lymphatic system, which are interconnected to form a basically closed "pipeline system". A normal heart is a powerful muscular organ that beats rhythmically day and night, like a pump. The heart contracts and expands, keeping blood flowing through the circulatory organs. When blood flows in the blood vessels, whether the heart contracts or relaxes, it exerts a certain pressure on the blood vessel walls. When the heart contracts, the pressure in the aorta is highest, and the blood at this time is called "high pressure"; when the left ventricle relaxes, the pressure in the aorta is lowest, so it is called "low pressure". What we usually call "blood pressure" actually refers to the blood pressure measurement of the brachial artery in the upper arm, that is, the blood pressure of the blood vessels in the armpit, which is an indirect measurement of the blood pressure in the large arteries. Usually when we measure blood pressure, the blood pressure on the right side and the left side are different. The maximum difference can be 10 mmHg and the minimum difference is less than 5 mmHg.

It is normal for blood pressure to rise during pregnancy. For pregnant women with a baseline blood pressure of 110/70 mmHg, if their blood pressure increases to 140/100 mmHg in the late pregnancy, this is not considered normal and is called gestational hypertension. Normal blood pressure should not exceed (130/90 mmHg), or not exceed (30/15 mmHg) compared with the baseline blood pressure.

Friends who have pregnant women at home need to pay attention. The blood pressure of pregnant women will have deviations, but it will be within a reasonable range. Parents need to always pay attention to the mood and diet of pregnant women, and go to the hospital for regular check-ups to prevent the blood pressure of pregnant women from rising, which is the so-called preeclampsia. There are many cases of pregnant women suffering from gestational hypertension. Some people do not pay attention to their diet at the beginning, which leads to high blood pressure and easily causes gestational hypertension. Therefore, pregnant women need to make reasonable plans for their bodies.
