Renovascular Hypertension

Renovascular hypertension is an elevation of blood pressure that originates from a narrowing of the arteries that carry blood to the kidneys, which disrupts the body's natural regulation of pressure.

Common causes: It is usually due to a reduction in the caliber of a renal artery, either from deposits on its walls or from a thickening of them, which reduces blood flow to the affected kidney.

Frequent symptoms: It may present as blood pressure that is difficult to control, persistent headache, or high readings that appear unusually for the person's age.

Which specialist treats it? The evaluation falls to the nephrologist and the internist, who study kidney function and circulation. If blood pressure readings aren't controlled or appear unusually, it's a good idea to schedule a visit for a complete evaluation.
