When Exercise Can Kill — The Rare Risk of Rhabdomyolysis

A recent WebMD article1 addresses a rare but potentially fatal muscle disorder called rhabdomyolysis, or rhabdo for short. Estimates suggest it may affect 22 people out of 100,000, and muscle trauma due to overexertion is a common cause. Your skeletal muscles are under your volitional control, which is why they’re also known as voluntary muscles.

You engage them when walking and moving. When skeletal muscle is damaged through overexertion injury, the muscle starts dumping myoglobin, an iron- and oxygen-binding muscle protein, into your bloodstream. Excessive myoglobin obstructs your kidney’s filtration system, which can lead to acute renal damage.

Rhabdo causes kidney failure in up to 40 percent of cases, so early diagnosis and rapid medical intervention is crucial. Liberated potassium leading to hyperkalemia (high potassium in your blood), which can occur within hours after muscle injury, can also be life threatening.

Signs and Symptoms of Rhabdo

The following symptoms are considered “classic” rhabdo symptoms, although all may not necessarily be present in all cases:

  • Muscle swelling
  • Pain in the affected muscle group
  • Muscle weakness or trouble moving your limbs
  • Dark and scant urine output
