What Are Some Causes of Orange Urine and Nausea?

Orange urine may be the result of dehydration, certain laxatives, reaction to vitamins or supplements, or liver dysfunction, says Healthline. If it persists along with nausea or other symptoms, it may indicate a serious health condition and requires medical care.

When a person is not getting an adequate amount of water, urine becomes more concentrated and may appear orange. Drinking water should turn the urine back to a clear yellow within a few hours if the color change is due to dehydration. Laxatives that contain senna or supplements that contain B vitamins, vitamin C or beta carotene may also turn urine orange. Certain chemotherapy drugs cause orange urine due to kidney or bladder damage. An ongoing problem with orange urine that does not improve with increased hydration, discontinuation of supplements or other changes may indicate a serious problem with the liver or bile, warns Healthline.

Other symptoms of liver disease that may accompany orange urine include nausea and loss of appetite, fatigue, abdominal swelling, disorientation, and easy bruising or bleeding, advises LiverSupport.com. Jaundice, a condition in which the liver cannot adequately break down bilirubin, can cause yellowing of the skin and eyes and light-colored stools in addition to orange or dark urine. Treatment of liver disease is more successful the sooner it begins, so prompt medical attention is crucial.
