High Blood Pressure During Pregnancy: What to Expect

Pregnancy is a miraculous journey filled with anticipation and joy. However, it’s also a time when a woman’s body undergoes significant changes, including fluctuations in blood pressure. High blood pressure during pregnancy is a common concern that requires careful monitoring and management to ensure the health and well-being of both the mother and the baby.

In this comprehensive guide, we’ll delve deep into the intricacies of high blood pressure during pregnancy, including its causes, risks, and effective management strategies.

Why is there high blood pressure during pregnancy?

High blood pressure, medically known as hypertension, is a condition characterized by elevated blood pressure levels. During pregnancy, it’s classified into several categories:

Gestational Hypertension

Gestational hypertension refers to high blood pressure that develops for the first time during pregnancy. Typically, it arises after the 20th week of gestation and often resolves after childbirth.

Chronic Hypertension

Chronic hypertension is a pre-existing condition in which a woman has high blood pressure before becoming pregnant or before the 20th week of pregnancy.


Preeclampsia is a severe condition characterized by high blood pressure and damage to organs such as the liver and kidneys. It usually occurs in the second half of pregnancy and can be life-threatening if left untreated.

Diagnosis and Monitoring

Diagnosing high blood pressure during pregnancy involves regular blood pressure measurements at prenatal check-ups.
