This color is often confused with hematuria, but urinalysis test results are different in this case. The cause is generally myoglobinuria, a condition that causes muscle cells to release an oxygen-carrying substance called myoglobin during muscle destruction. Alcohol and drug abuse or physical trauma can set this process in motion. However, some medications and foods can also cause brown discoloration. For example, the urine can turn brown or tea-colored after eating large quantities of rhubarb.
