  Complications of Chronic Hypertension in Pregnancy

Placental insufficiency : is when the placenta, is not able to deliver adequate nutrients, oxygen etc to the fetus in the womb.

Intra-uterine growth restriction: this is caused by many factors, but mainly, when the maternal supply of oxygen and nutrients, is compromised, leading to poor fetal growth and small for gestational age...of the fetus.


Placental abruption:  this happens when the placenta, the main supply of nutrients from the mother-to-be, to the fetus is either partially or completely peeled off the wall of the uterus  (womb)

This leads to bleeding. It is a very serious medical condition, if left untreated immediately.

Prematurity:  this is when the baby is born, before the 37 th week of pregnancy obviously, this gives the newborn less time to develop in the womb.

This can lead to other medical problems for this newborn. This will depend on the severity..... like those born before the 25 th week of gestation.
