Renovascular hypertension

Definition

Renovascular hypertension is high blood pressure due to narrowing of the arteries that carry blood to the kidneys. It is a form of secondary hypertension.

Alternative Names

Causes

When the kidney arteries become narrow, less blood flows to the kidneys. The kidneys mistakenly respond as if your blood pressure is low and give off hormones that tell the body to retain salt and water. This causes your blood pressure to rise.

Many different diseases can cause narrowing of the renal arteries. Hardening of the arteries from high cholesterol is one of the most common. Most patients have the typical risk factors for atherosclerosis, including high blood pressure, high cholesterol, and diabetes.

Fibromuscular dysplasia is another cause, particularly in women under age 50.
