A rare but serious muscle-destroying condition called rhabdomyolysis has been linked to the death of a marathon runner, raising concerns among athletes and medical professionals. The condition occurs when damaged skeletal muscles release their contents into the bloodstream, potentially causing kidney failure and other life-threatening complications. Symptoms can include severe muscle pain, weakness, and dark urine, though they may not always appear immediately after exertion. Experts warn that extreme physical strain, dehydration, or certain medications can trigger the dangerous breakdown of muscle tissue.
