Many changes occur due to pregnancy. Most of them are normal, some require special attention. High blood pressure is one of such conditions. This is medically known as Pregnancy-Induced Hypertension (PIH). Many pregnant women often mistake these signs for fatigue. Understanding the PIH symptoms, causes and complications, can help keep you and your baby safe.
What is Pregnancy-Induced Hypertension(PIH)?
Pregnancy-Induced Hypertension(PIH) stands for high blood pressure which occurs during the pregnancy period. PIH usually occurs after 20 weeks of pregnancy. BP Normal Range in pregnancy of 140/90 mm Hg or above is considered high. One high blood pressure reading alone does not necessarily diagnose PIH. Therefore, routine prenatal exams are a must.
People often get confused between PIH and preeclampsia. Both are two different conditions. Gestational hypertension refers to high blood pressure developing after week 20. This condition has no signs of organ dysfunction. In preeclampsia, however, high blood pressure is linked to symptoms that suggest the possibility of dysfunction in other organs.

These may include:
Kidney problems
Liver problems
Stroke

Seizures
Seizures may also happen with a serious condition known as eclampsia. This requires immediate medical attention. High blood pressure can result in a premature delivery. Delivery may be recommended if the risks get too high.
