Why can pregnant women with low blood pressure get pregnancy-induced hypertension? There are also four kinds of people who will also be targeted by pregnancy-induced hypertension!
During pregnancy, women face a variety of health challenges, among which pregnancy-induced hypertension is a serious complication of pregnancy that poses a potential threat to the health of both mother and baby. Interestingly, even pregnant women who usually have low blood pressure can develop this disease associated with high blood pressure. So, why do pregnant women with low blood pressure also suffer from pregnancy-induced hypertension? In addition to pregnant women with low blood pressure, who else is more likely to develop pregnancy-induced hypertension? Below, we'll explore these questions and hopefully unravel this mystery for you and give you a clearer picture of your pregnancy health.
Definition and harms of pregnancy-induced hypertension
Pregnancy-induced hypertension, also known as gestational hypertension, is a common complication of pregnancy, usually after 20 weeks of pregnancy. It is mainly manifested as increased blood pressure and proteinuria, and in severe cases, it can cause pregnancy with severe proteinuria, edema, abnormal liver function, etc., which has a serious impact on the health of the mother and fetus. Why hypotensive pregnant women can also develop pregnancy-induced hypertensionAlthough hypotensive pregnant women often have blood pressure levels below the normal range, they can also develop pregnancy-induced hypertension. This may be related to an imbalance in the regulation mechanism of blood pressure during pregnancy, including abnormal vascular tone regulation, insufficient blood volume increase, and other factors. In addition, hypotensive pregnant women may have other potential risk factors, such as familial genetics, kidney disease, etc., that increase the risk of pregnancy-induced hypertension.
Why pregnant women with low blood pressure may also develop pregnancy-induced hypertension
Although hypotension is generally considered a relatively stable physiological condition, it can be a potential risk factor for pregnancy-induced hypertension during pregnancy. This is mainly due to the increase in progesterone levels in pregnant women, increased blood volume, and physiological changes in the circulatory system during pregnancy. These factors may contribute to abnormal vascular tone regulation in pregnant women, which in turn increases the risk of pregnancy-induced hypertension. Abnormal vascular tone regulationHypotensionDuring pregnancy, the levels of some hormones in the body change, such as an increase in progesterone and prostaglandins, which affect the contraction and relaxation of blood vessels. In some hypotensive pregnant women, changes in this hormone level may cause abnormal regulation of vascular tone, making blood vessels less responsive to constriction and relaxation, increasing the risk of pregnancy-induced hypertension.
Inadequate volume gain
Normally, a pregnant woman's blood volume increases gradually during pregnancy to meet the needs of the fetus and maternal tissues. However, in some hypotensive pregnant women, due to insufficient volume gain, the amount of blood in the blood vessels is insufficient to meet the physiological needs of pregnancy, which may lead to dysfunction of vasoconstriction, thereby increasing the risk of pregnancy-induced hypertension. Other potential risk factorsIn addition to the above factors, hypotensive pregnant women may have other potential risk factors, such as family genetics, kidney disease, etc., which may also increase their risk of developing pregnancy-induced hypertension. Therefore, for hypotensive pregnant women, timely prenatal examination and close attention to the health status during pregnancy are of great significance to prevent and reduce the occurrence of pregnancy-induced hypertension.
Why does pregnancy-induced hypertension target pregnant women with low blood pressure?
The reason why pregnancy-induced hypertension targets pregnant women with low blood pressure is not accidental. During pregnancy, the blood pressure of pregnant women usually changes, and hypotensive pregnant women have low blood pressure, which may be further aggravated during pregnancy. In addition, a substance called angiotensin may increase in pregnant women during pregnancy, which can lead to poor vasoconstriction and increase the risk of pregnancy-induced hypertension. In addition, hypotensive pregnant women may have endothelial dysfunction, which is also an important factor in the development of pregnancy-induced hypertension.
Four other groups of people who are susceptible to pregnancy-induced hypertension
Older Pregnant Women Older women may have their blood vessels affected due to the decline in physical function, resulting in poor blood pressure control and increased risk of pregnancy-induced hypertension. Pregnant women who are pregnant for the first time because they have not experienced the physical changes of pregnancy may not be able to adjust their bodies during pregnancy enough, and are prone to poor blood pressure control, increasing the likelihood of pregnancy-induced hypertension. Due to the increase in the number of fetuses in pregnancy, the blood circulation in the uterus increases, which puts forward higher requirements for the maternal heart and vascular system, and increases the risk of pregnancy-induced hypertension.
Pregnant women with high blood pressure or diabetes before pregnancy
Pregnant women who already have high blood pressure or diabetes before pregnancy may have problems with blood pressure or blood sugar control after pregnancy, increasing the risk of pregnancy-induced hypertension. The above are the reasons why pregnancy-induced hypertension targets pregnant women with low blood pressure and four other groups of people who are susceptible to pregnancy-induced hypertension. During pregnancy, many changes will occur in the body of pregnant women, and maintaining good lifestyle habits, regular prenatal check-ups, and timely detection and treatment of potential problems are essential to prevent the occurrence of pregnancy-induced hypertension.
