Dark urine may appear brown, red, maroon, or dark yellow and is most commonly caused by dehydration, which makes urine more concentrated and darker in color.
Normal urine is typically pale yellow due to natural pigments. When fluid intake is low, waste products become more concentrated as the kidneys filter them from the blood. Urine color studies have shown that many samples indicate less than optimal hydration. When the body does not have enough fluids, urine becomes more concentrated and darker in color.
Dark urine can also be caused by certain foods like beets or rhubarb, medications, or medical conditions such as liver disease, hepatitis, rhabdomyolysis, or bladder infections. If urine remains dark even after drinking enough water, it may signal excess or abnormal waste in the body and should be medically evaluated.
A healthcare professional can determine the cause through proper testing and recommend appropriate treatment.
