Blood pressure and its risks in pregnancy

Blood pressure and its risks in pregnancy

Pregnancy means one has to go through a lot of physical as well as mental changes. There is a change in hormone levels and it leads to a lot of issues in a body.

It is said that in a human body, the average blood pressure for pregnancy can also increase. Sometimes high blood pressure is present from before and in some cases it happens after one conceives.

Here is what one can face when they have high blood pressure during pregnancy:

Gestational hypertension

This mainly develops in a woman mostly after reaching their 20th week of pregnancy. There is no presence of excess protein in the urine or any other signs of organ damage. But some women with this gestational hypertension can eventually develop preeclampsia.

Chronic hypertension

It is a high blood pressure condition which is present in the body even before one gets pregnant. Sometimes it can occur post pregnancy but happens before the pregnancy reaches its 20th week. But blood pressure has no particular symptom from which it can be identified and so one may not determine that when exactly the level became high.

Chronic hypertension with superimposed Preeclampsia

This is a very chronic condition that occurs in women even before pregnancy and once they get pregnant, the worsening of high blood pressure and presence of protein in urine and all the other blood pressure related problems can make the pregnancy tenure a bit complicated.


This mainly occurs when the hypertension develops (which is mostly 20 weeks after pregnancy) and then it is associated with the signs of damage of the other organ systems like the liver, kidneys, blood and brain. If the preeclampsia is left untreated then it can turn from serious to fatal and this condition can be complicated for both the mother and the baby. This can also lead to the development of seizures. Previously this preeclampsia was diagnosed on if the woman had high blood pressure in pregnancy or if they had protein in urine but now it can be diagnosed even if there is not protein in urine.

Problems of high pressure in pregnancy:

  • There is a decrease of blood flow in the placenta and if the placenta does not get enough blood then the baby might receive few nutrients and lesser oxygen. It can lead to the slow growth of the foetus and as a result, there will be a premature birth.
  • There can be a placental abruption. The preeclampsia can increase the risk of this condition in which the placentas gets separated from the inner wall of the uterus before the delivery of the baby. This severe abruption can cause heavy bleeding. It can be a life threatening situation for the baby.
  • This can lead to injury to the other organs and hypertension can result into the decreased or slow growth of the baby.

So, blood pressure and pregnancy are very much related and high blood pressure needs to be treated the moment they are diagnosed.
