why is that some women have hypertension when they are pregnant?

Question

it is called gestational hypertension.it appears at mid pregnancy and disappears after pregnancy why is that?

Answer 1

Pregnancy-induced hypertension is a form of high blood pressure in pregnancy. It occurs in about 5 percent to 8 percent of all pregnancies. It occurs most often in young women with a first pregnancy. It is more common in twin pregnancies, in women with chronic hypertension, preexisting diabetes, and in women who had PIH in a previous pregnancy.

The cause is unknown. Some conditions may increase the risk of developing Pregnancy-induced hypertension, including the following:

* pre-existing hypertension (high blood pressure)
* kidney disease
* diabetes
* PIH with a previous pregnancy
* mother younger than 20 or older than 40
* multiple fetuses (twins, triplets)

This type of hypertension can lead to a more severe condition called pre-eclampsia, and then HELLP syndrome.

Although no one is sure why it happens, some reasonable suggestions are: it may be partly because of the increase in blood volume that pregnant women have (the more blood volume= the higher the pressure on the arterial walls= the higher the blood pressure basically), and it may also have to do with all of the hormonal changes that occur during pregnany.

Here is one website to check out (but there are many):
