Kidney failure, acute

DEFINITION

Acute kidney failure occurs when your kidneys suddenly become unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of wastes may accumulate, and your blood's chemical makeup may get out of balance. Acute kidney failure — also called acute renal failure or acute kidney injury — develops rapidly over a few hours or a few days. Acute kidney failure is most common in people who are already hospitalized, particularly in critically ill people who need intensive care. Acute kidney failure can be fatal and requires intensive treatment. However, Acute kidney failure may be reversible.

SYMPTOMS

• Decreased urine output
• Fluid retention
• Drowsiness
• Shortness of breath
• Fatigue
• Confusion
• Nausea
• Seizures or Coma in severe cases
• Chest pain or pressure

CAUSES

1. Impaired blood flow to the kidneys
2. Damage to the kidneys
3. Urine blockage in the kidneys

RISK FACTORS

• Being hospitalized
• Advanced age
• Diabetes
• High blood pressure
• Heart failure

Complications: 1. Fluid buildup 2. Chest pain 3. Muscle weakness 4. Permanent kidney damage 5. Death

PREPARING FOR YOUR APPOINTMENT

Prepare questions for your doctor such as:

• Are my kidneys working properly?
• Do I have kidney failure?
• What's causing my kidney problems?
• What are my treatment options?

TESTS AND DIAGNOSIS

Urine output measurements, Urine tests, Blood tests, Imaging tests, Removing a sample of kidney tissue for testing.

TREATMENTS AND DRUGS

Treatment for Acute kidney failure typically requires a hospital stay and depends on the underlying cause. Treatments include balancing Fluids, controlling blood potassium levels, restoring blood calcium levels, and dialysis if needed.

Lifestyle and Home Remedies: Pay attention to labels when taking over-the-counter pain medications, work with your doctor to manage kidney problems, make a healthy lifestyle a priority.
