10 Signs Your Kidneys Are Crying For Help

Acute kidney failure occurs when your kidneys suddenly become unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of wastes may accumulate, and your blood’s chemical makeup may get out of balance.
Acute kidney failure — also called acute renal failure or acute kidney injury — develops rapidly, usually in less than a few days. Acute kidney failure is most common in people who are already hospitalized, particularly in critically ill people who need intensive care.

Acute kidney failure can be fatal and requires intensive treatment. However, acute kidney failure may be reversible. If you’re otherwise in good health, you may recover normal or nearly normal kidney function.Signs and symptoms of acute kidney failure may include:
Decreased urine output, although occasionally urine output remains normal
Fluid retention, causing swelling in your legs, ankles or feet
Shortness of breath
Irregular heartbeat
Chest pain or pressure
Seizures or coma in severe casesAcute kidney failure can occur when:
You have a condition that slows blood flow to your kidneys
You experience direct damage to your kidneys
Your kidneys’ urine drainage tubes (ureters) become blocked and wastes can’t leave your body through your urineDiseases and conditions that may slow blood flow to the kidneys and lead to kidney injury include:
Blood or fluid loss
Blood pressure medications
Heart attack
Heart disease
Liver failure
Use of aspirin, ibuprofen (Advil, Motrin IB, others), naproxen sodium (Aleve, others) or related drugs
Severe allergic reaction (anaphylaxis)
