Orange urine can be a symptom of eating carotenoids (foods and supplements containing beta-carotene), infection, dehydration, certain medications, injury, or disease. Urine that appears orange results from changes in the contents of the urine. It may occur in conditions affecting the urinary tract itself or along with more generalized conditions, such as infection and cancer.
Urinary tract infections and dehydration are common causes of orange urine. Other common causes include injury to urinary tract structures (kidney, bladder, ureters or urethra) or hepatitis. Cancer of the pancreas, liver, kidneys and bladder are further causes of orange urine. Depending on the cause, orange urine may occur frequently or periodically, and it may be accompanied by frequent urination that often produces only a small amount of urine, cloudy urine, foul-smelling urine, or other changes in urination.
