Hypertension During Pregnancy: Understanding the Three Classifications

Hypertension during pregnancy is classified into three main types, each with distinct characteristics and implications for both mother and baby. Understanding these categories is essential for effective monitoring and management throughout pregnancy.

1. Gestational Hypertension

The first category is gestational hypertension, which occurs due to pregnancy itself and typically develops after the 20th week of gestation. This type can be further divided into three subcategories. The first involves elevated blood pressure without the presence of protein in the urine or noticeable swelling, and is often referred to as gestational hypertension.

The second subcategory is more severe and involves high blood pressure accompanied by proteinuria and edema. This condition is known as preeclampsia and requires careful medical attention due to its potential complications. The third and most critical stage is when seizures occur in a woman with preeclampsia, which is diagnosed as eclampsia. Eclampsia poses serious risks to both the mother and the unborn child and necessitates immediate intervention.

2. Chronic Hypertension with Superimposed Preeclampsia

The second classification involves women who already have a history of chronic hypertension prior to pregnancy. In such cases, the existing high blood pressure may worsen during pregnancy. This condition is referred to as chronic hypertension with superimposed preeclampsia and requires specialized care to manage both the pre-existing condition and any pregnancy-related complications that may arise.

3. Chronic Hypertension Diagnosed Early in Pregnancy

The third type of hypertension during pregnancy is chronic hypertension that is identified before the 20th week of gestation. Unlike the other types, this form does not involve proteinuria or swelling at the time of diagnosis. However, it still requires close monitoring throughout the pregnancy to ensure the health and safety of both the mother and the developing baby.

Recognizing the differences between these types of hypertension is crucial for expectant mothers and healthcare providers. Early detection and appropriate management can significantly reduce the risks associated with high blood pressure during pregnancy.
