Symptom #5: Tea Colored Urine
Myoglobinuria occurs when there is myoglobin in the urine and presents as tea-colored urine. It usually occurs due to muscle destruction or rhabdomyolysis. Myoglobin is found in muscle cells as it functions as a reserve of oxygen. Myoglobinuria is usually associated with fever, nausea, myalgia, and swollen painful muscles.
Once the muscle is damaged, myoglobin is released into the circulation and excreted by the kidneys. Ideally, the myoglobin is filtered and excreted with the urine. However, if there is too much myoglobin, it can cause occlusion of the renal filtration system resulting in acute renal insufficiency and acute tubular necrosis.
