What causes rhabdomyolysis?
Rhabdomyolysis has many causes. Some of the common ones include:
* muscle trauma or crush injury,
* severe burns,
* physical torture or child abuse,
* prolonged lying down on the ground (people who fall or are unconscious and are unable to get up for several hours),
* prolonged coma,
* severe muscle contractions from prolonged seizures,
* cocaine use with related hyperthermia (increased body temperature),
* extreme physical activity (running a marathon),
* drug and alcohol intoxication,
* low circulating phosphate, potassium, or magnesium levels in the blood (electrolytes),
* genetic muscle diseases (familial paroxysmal rhabdomyolysis),
* prolonged drowning or hypothermia (low core body temperature),
* medications: most notably statins used to treat high cholesterol [simvastatin (Zocor), atorvastatin (Lipitor), pravastatin (Pravachol), or lovastatin (Mevacor)] and other medications such as Parkinson's medication, psychiatric medications, anesthesia medications, HIV medications, colchicine,
* variety of viruses and some bacteria,
* severe hypothyroidism (low thyroid level), especially if the person is also taking statin drugs for cholesterol,
* lack of blood perfusion to a limb,
* some inflammatory disorders of the muscle, called myopathies, (myositis, dermatomyositis, polymyositis),
* venom from certain snake bites (mainly in Africa, Asia, and South America).
