The Renal Hypertension Guide - The Complete Guide to Symptoms, Causes, and Treatment

Renal hypertension (or renovascular hypertension) is high blood pressure caused by the narrowing of your arteries that carry blood to your kidneys. It is also sometimes called renal artery stenosis. Because your kidneys are not getting enough blood, they react by making a hormone that makes your blood pressure rise. What Are the Symptoms of Kidney Disease?High/worsening blood pressure.Decrease in the amount of urine or difficulty urinating.Edema (fluid retention), especially in the lower legs.A need to urinate more often, especially at night.Diagnosis is by physical examination and renal imaging with duplex ultrasonography, radionuclide imaging, or magnetic resonance angiography. Angiography is done before definitive treatment with surgery or angioplasty. Renovascular hypertension is the most common cause of secondary hypertension, high blood pressure that can be attributed to a specific cause. It is responsible for about 1 percent to 2 percent of the 50 million estimated cases of hypertension in the United States.
