You have been diagnosed with acute kidney injury. This means that you have had a sudden episode of kidney failure or damage that causes your kidneys not to work correctly. When both kidneys are healthy, they help filter out fluid and waste from the blood and body. Acute kidney injury has many causes. These include urinary blockages, infections such as COVID-19, lack of enough blood supply, a major health event such as heart surgery, and medicines that can injure kidneys. In some cases, acute kidney injury is short-term (temporary). This type lasts several days to a few months. This is because the kidney can repair itself. Acute kidney injury can also result in chronic kidney disease or end-stage renal failure. Here are some directions for you to follow as you recover.

• Follow any directions for eating and drinking given to you by your doctor.
  • Drink less fluid, if directed by your doctor.
  • Keep a record of everything you eat and drink.
• Measure the amount of urine and stool you have each day.
• Weigh yourself every day, at the same time of day, and in the same kind of clothes. Keep a daily record of your daily weights.
• Take your temperature every day. Keep a record of the results.
• Learn to take your own blood pressure (BP). Your doctor can teach you how to correctly measure your BP. Keep a record of your results. Bring the record to your follow-up appointments. Ask your doctor when you should seek emergency medical attention. Your doctor will tell you what blood pressure reading is dangerous.
• Stay away from people who have infections. This includes people with colds, bronchitis, or skin conditions.
• Practice good personal hygiene. Wash your hands often. This is especially important if you have a catheter in place when you leave the hospital. Doing so helps keep you safe from infection.
• Take your medicines exactly as directed. If you are confused about how to take any of your medicines, contact your doctor.
• You may need frequent blood and urine tests. These are done to keep track of your kidney function.

Follow up with your doctor as advised.
