Intake of water causes changes in urine coloration. Urine becomes clearer as a person drinks more water while reduced water intake increases the concentration of the yellow pigment. In severe cases of dehydration, urine becomes amber colored, says Mayo Clinic. Urine turns pale in patients who are taking diuretics, medications that rid the body of excess water or due to infection.
Vitamin B and C supplements can cause urine to turn orange, while taking several multivitamins may turn urine blue or green. Eating certain foods may alter the color of urine. Laxatives may cause urine to turn pink. Asparagus causes urine to turn greenish, while beets and blackberries cause a reddish or pinkish pigmentation, according to WebMD. These changes are harmless because they occur due to the pigmentation or compounds in the food or medication.
Green or blue urine may result from a bacterial infection or familial hypercalcaemia, a rare genetic anomaly. Brown urine results from kidney disorders, while kidney stones make urine appear cloudy, says WebMD. Orange urine, coupled with yellowing skin, may signal a malfunctioning liver. An individual should seek medical help in the event of these indications or blood in his urine, which may be a symptom of a urinary tract infection. While the former condition is typically painful, painless but bloody urine may be a sign of cancer, cautions Mayo Clinic.
