NYC marathon runner killed by silent condition. Experts expose signs
Rachel Apa collapsed and died at just 24 while running the New York City Marathon. Doctors are now issuing an urgent warning about the muscle condition behind her death, rhabdomyolysis.

TL;DR
- Rachel Apa, 24, died from rhabdomyolysis shortly after collapsing near the end of the New York City Marathon.
- Rhabdomyolysis occurs when muscles break down rapidly, releasing damaging chemicals into the bloodstream that can overwhelm the kidneys and lead to organ failure.
- Intense or prolonged exercise is a major risk factor, as it pushes muscle fibers beyond the body's capacity to repair.
- Early symptoms are subtle and include muscle aches, profound weakness, swelling, and dark urine, which can be easily dismissed by athletes.
- While rhabdomyolysis is treatable with IV fluids and medications, severe cases can be life-threatening, potentially causing cardiac arrest or multiple organ failure.
- Prompt diagnosis through blood and urine tests, and treatment in an emergency room, can prevent severe complications and often leads to full recovery.
- Multiple professional athletes have suffered from rhabdomyolysis and successfully returned to their sports.
- Prevention involves avoiding overexertion, staying hydrated, and taking frequent breaks during exercise.
