What is acute kidney failure?

Acute kidney failure (acute renal failure or acute kidney injury) occurs when the kidney is not able to filter waste products from the blood. When the kidney is not able to function properly, harmful waste levels can accumulate, and the blood chemicals can get out of the balance.

What are the symptoms?

Symptoms and signs of acute kidney failure that includes:

  • Decreased urine output, although occasionally urine output remains normal
  • Fluid retention, causing swelling in your legs, ankles or feet
  • Weakness
  • Shortness of breath
  • Fatigue
  • Confusion
  • Nausea
  • Irregular heartbeat
  • Chest pain or pressure
  • Seizures or coma in severe cases

In some cases, kidney failure does not leave signs or symptoms, so it is essential to get lab tests to find the exact reason.
If you have these symptoms then consult the doctor right away to learn what treatment plan you need to get.
