Rhabdomyolysis Symptoms and Causes
What are the symptoms of rhabdomyolysis?
The muscle damage causes inflammation leading to tenderness, swelling, and weakness of the affected muscles. The dark urine color is due to myoglobin being excreted in the urine by the kidney as it tries to rid the body of the muscle breakdown products.
Symptoms related to the expected complications of rhabdomyolysis include:
- symptoms of kidney failure, which may include swelling of the hands and feet;
- shortness of breath as excess fluid builds up in the lungs,
- symptoms of hyperkalemia (elevations in potassium in the blood) such as weakness, nausea, lightheadedness, and palpitations due to heart rhythm disturbances); and
- disseminated intravascular coagulation, a disruption of the normal blood clotting process, may occur as unexplained bleeding.
