Rhabdomyolysis is a potentially life-threatening condition that occurs when damaged muscle tissue breaks down and releases myoglobin into the bloodstream. Too much myoglobin in the blood can lead to kidney damage or kidney failure. Muscle injuries, drug use, certain genetic disorders, alcohol abuse, and some surgical procedures can all cause this condition. A variety of symptoms can point to rhabdomyolysis.
Discolored urine is a common symptom of rhabdomyolysis. Dark or tea-colored urine is often one of the first signs of a problem. Many people mistakenly believe this indicates blood in the urine, which has its own implications. However, when a person has rhabdomyolysis, it is excess myoglobin, not blood, that causes the discoloration.
