What is orange urine? 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. The contents of urine may cause orange urine and can be the result of eating certain foods, such as carrots or candy, or consuming any food with orange dye. The duration and course of orange urine can vary depending on the cause. Orange urine alone may not be serious, but if it accompanies other symptoms it may indicate a serious infection. Seek immediate medical care (call 911) for serious symptoms, such as high fever (higher than 101 degrees Fahrenheit), severe lower back pain, urinary retention, or persistent vomiting. Seek prompt medical care if you are being treated for orange urine but mild symptoms recur or are persistent.
