About this topic
The kidneys are bean-shaped organs in the back of your belly, just above your waist. They filter your blood and get rid of waste products and extra fluid from your body. The kidneys also help to control your blood pressure and produce red blood cells. The waste is turned into urine. Sometimes, your kidneys do not work well. Kidney failure is an illness where your kidney stops cleaning waste from the blood.
Kidney failure may be acute or chronic.
What are the causes?
- Acute − Happens all of a sudden. It may be caused by infection, drugs, chemicals, or trauma. A blockage in your
urinary tract or
- low body fluids may also cause this.
- Chronic − Happens slowly over time. It may be caused by illnesses like high blood pressure or diabetes.
- Acute on chronic − Sudden decline in someone with chronic kidney disease.
What are the main signs?
- Passing less urine or no urine at all or blood in the urine
- Feeling short of breath
- Swelling, often in legs or feet
- Throwing up or not hungry
- Feeling weak or sluggish, confused, or having trouble sleeping
- Muscle cramps
- Unusual itching
How does the doctor diagnose this health problem?

How does the doctor treat this health problem?
Doctors need to treat this illness to make your kidneys work again. If your kidneys are badly damaged, your doctor will need to use a machine or treatment called dialysis to remove the waste products from your blood. Sometimes, a new healthy kidney from someone else is used to replace your kidneys. This is a kidney transplant.
Are there other health problems to treat?
There may be other problems to treat based on what is causing your kidney failure

Your doctor may order drugs to:

What changes to diet are needed?
- You need to limit your food and fluid intake. Your doctor will tell you what you can and cannot eat. This will help lessen the work of your recovering kidneys.
- Eat high-carb, low-protein meals. Some foods high in good carbs are:
- Fresh fruit like oranges, apples, pears, peaches, and watermelon
- Vegetables like broccoli, spinach, carrots, tomatoes, and cabbage
- Limit your salt by not using table salt, sauces, canned foods, salted snacks, and foods that are cured.
