What is the treatment for acute kidney failure?

Your treatment will depend on the cause of your acute kidney failure. The goal is to restore normal kidney function. Preventing fluids and wastes from building up in your body while your kidneys recover is important. In the majority of cases, a kidney specialist called a “nephrologist” makes an evaluation.


Your doctor will restrict your diet and the amount of liquids you eat and drink. This will reduce the buildup of toxins that the kidneys would normally eliminate. A diet high in carbohydrates and low in protein, salt, and potassium is usually recommended.


Your doctor may prescribe antibiotics to treat or prevent any infections that occur at the same time. Diuretics may help your kidneys eliminate fluid. Calcium and insulin can help you avoid dangerous increases in your blood potassium levels.


You may need dialysis, but it’s not always necessary, and it will likely only be temporary. Dialysis involves diverting blood out of your body into a machine that filters out waste. The clean blood then returns to your body. If your potassium levels are dangerously high, dialysis can save your life.

Dialysis is necessary if there are changes in your mental status or if you stop urinating. You may also need dialysis if you develop pericarditis or inflammation of the heart. Dialysis can help eliminate nitrogen waste products from your body.
