Hypertensive Kidney Disease: Symptoms & Signs

Medically Reviewed on 11/24/2021

Hypertensive kidney disease refers to damage to the kidneys caused by chronic, or long-term, high blood pressure (hypertension). High blood pressure is one of the main causes of kidney failure. Most people with high blood pressure do not have symptoms. Like high blood pressure, early kidney disease often does not produce symptoms.

In later stages, hypertensive kidney disease leads to the characteristic signs and symptoms of kidney dysfunction and sometimes, kidney failure. Associated symptoms and signs can include

  • worsening blood pressure,
  • decrease in amount of urine or difficulty urinating,
  • edema (fluid retention) that is most pronounced in the lower legs, and
  • a need to urinate more often, especially at night.

Keeping blood pressure under control with lifestyle modifications and medications can help prevent kidney disease.
