By Mayo Clinic staffSigns 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
- Drowsiness
- Shortness of breath
- Fatigue
- Confusion
- Seizures or coma in severe cases
- Chest pain related to pericarditis, an inflammation of the sac-like membrane that envelops your heart
Because acute kidney failure is usually a complication of some other serious disorder, initially the signs and symptoms may go unnoticed or be attributed to the underlying disease.
