ComplicationsBy Mayo Clinic staff
Potential complications of acute kidney failure include:
- Fluid buildup. Acute kidney failure may lead to a buildup of fluid in your chest, which can cause shortness of breath.
- Chest pain. If the lining that covers your heart becomes inflamed, you may experience chest pain.
- Muscle weakness. When your body's fluids and electrolytes — your body's blood chemistry — are out of balance, muscle weakness can result. Elevated levels of potassium in your blood are particularly dangerous.
- Permanent kidney damage. Occasionally, acute kidney failure causes permanent loss of kidney function, or end-stage renal disease. People with end-stage renal disease require either permanent dialysis — a mechanical filtration process used to remove toxins and wastes from your body — or a kidney transplant to survive.
- Death. Acute kidney failure can lead to loss of kidney function and, ultimately, death. The risk of death is highest in people who had kidney problems before acute kidney failure.
