Acute Kidney Injury


Acute kidney injury (AKI) is also called acute kidney failure, or acute renal failure. AKI happens when your kidneys suddenly stop working correctly. Normally, the kidneys remove fluid, chemicals, and waste from your blood. These wastes are turned into urine by your kidneys. AKI usually happens over hours or days. When you have AKI, your kidneys do not remove the waste, chemicals, or extra fluid from your body. A normal amount of urine is not produced. AKI is usually temporary, it can take days to months to recover. AKI can also become a chronic kidney condition.


Call 911 if:

  • You have sudden chest pain or trouble breathing.

Seek care immediately if:

  • Your symptoms get worse.

Contact your healthcare provider if:

  • Your symptoms return.
  • Your blood sugar or blood pressure level is not within the range your healthcare provider recommends.
  • You have questions or concerns about your condition or care.


Your healthcare provider may tell you to eat food low in sodium (salt), potassium, phosphorus, or protein. A dietitian can help you plan your meals.

Drink liquids as directed:

Your healthcare provider may recommend that you drink a certain amount of liquids. This will help your kidneys work better and decrease your risk for dehydration. Ask how much liquid to drink each day and which liquids are best for you.

Prevent acute kidney injury:

  • Manage other health conditions such as diabetes, high blood pressure, or heart disease. These conditions increase your risk for acute kidney injury. Take your medicines for these conditions as directed. Also, monitor your blood sugar and blood pressure levels as directed. Contact your healthcare provider if your levels are not in the range he or she says it should be.
  • Talk to your healthcare provider before you take over-the-counter-medicine. NSAIDs, stomach medicine, or laxatives may harm your kidneys and increase your risk for acute kidney injury. If it is okay to take the medicine, follow the directions on the package. Do not take more than directed.
  • Tell healthcare providers you have had acute kidney injury before you get contrast liquid for an x-ray or CT scan. Your healthcare provider may give you medicine to prevent kidney problems caused by the liquid.

Follow up with your healthcare provider as directed:

You will need to return for more tests to make sure your kidneys are working properly. You may also be referred to a kidney specialist. Write down your questions so you remember to ask them during your visits.
