Rhabdomyolysis is a group of symptoms. It caused by the breakdown of muscle tissue. Proteins called myoglobin are then released into the blood flow. These proteins can cause severe damage to the kidneys.
The muscle damage may be caused by:
- Excessive muscle activity
- Certain muscle diseases
muscle injuries such as a crush injury
- Overuse of alcohol or illicit drugs
Body is too cold—
Body is too hot—
Contact with electrical current

To confirm the diagnosis your may test:
- Blood—to look for markers of muscle damage
- Urine—to look for myoglobin, a protein released with muscle damage (only appears in urine if there are high levels in blood)
The activity of your muscles and heart may be tested. This can be done with:
—heart may be affected by electrolytes changes
Treatment may include:
Large amounts of fluid are the main treatment. The fluids are usually given by IV. This will help to quickly flush the myoglobin out of the kidneys. It can help the kidneys work well again.
Bicarbonate may be used to minimize myoglobin's toxic effects.
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:
