• Rhabdomyolysis


    Rhabdomyolysis occurs when skeletal muscles are damaged and release myoglobin into the bloodstream. Myoglobin is an iron-containing pigment that can cause severe damage to the kidneys.


    Rhabdomyolysis results from any condition that causes significant muscle damage. These include:

    Risk Factors

    Factors that may increase your chance of muscle damage include:
    • Extreme exertion, such as running a marathon
    • Heat stroke
    • Use of some prescription drugs
    • Alcohol or drug abuse
    • Severe seizures or convulsions


    The most common symptoms include:
    • Dark urine—brown or red in color
    • Muscle pain
    • Muscle weakness
    Other symptoms include:
    • Muscle swelling
    • Back pain
    • Nausea and vomiting
    In severe cases, rhabdomyolysis may result in:

    The doctor will ask about your symptoms and medical history. A physical exam will be done. Tests may include:
    Your bodily fluids may be tested. This can be done with:
    • Urine tests
    • Blood tests
    The activity of your muscles and heart may be tested. This can be done with:


    Treatment may include:


    Giving large amounts of fluid is the main treatment. Fluids are usually given by IV. Hydration helps to quickly flush myoglobin out of the kidneys to restore their function.


    Bicarbonate may be used to minimize myoglobin's toxic effects.


    Dialysis is a procedure that uses a machine to filter blood when the kidneys are not functioning. The clean blood is then returned to your body.


    To reduce your chance of muscle damage and rhabdomyolysis:
      Drink plenty of fluids when:
      • Exercising
      • Sitting or working in hot, humid weather
    • Drink alcohol in moderation—maximum of two drinks per day for men and one drink per day for women
    • Avoid illicit drugs
