Secondary hypertension

There are two main types of high blood pressure: primary hypertension and secondary hypertension.

Secondary hypertension, also known as high blood pressure caused by an underlying medical condition, is a type of hypertension that has a known identifiable cause. This is in contrast to primary hypertension, which has no known specific cause. Secondary hypertension is less common, affecting only about 5-10% of people with high blood pressure.

Causes of secondary hypertension include kidney disease, adrenal disorders, thyroid disorders, congenital heart defects, and medications. The most prevalent cause of secondary hypertension is kidney disease, as the kidneys play a crucial role in regulating blood pressure.
