Green Urine ------------------------------------------------------------------------------ QUESTION: Please don't laugh at my question. I assure you it really happened and almost made me pass out. While passing my water I noticed that my urine was definitely a green color. I have no other symptoms, and it only happened once more after that but the color was less intense. Do I have anything to worry about? Will it happen again? ------------------------------------------------------------------------------ ANSWER: If it has disappeared without any other symptoms or complaints, you most probably are out of danger. You probably never had anything too serious to worry about anyway. The most common reason for green urine is the result of something you have eaten or ingested. Chlorophyll containing breath mints when taken in large quantities are a frequent cause. There are a number of other substances in common medications that may also provoke a green color; guaiacol contained in many cough medicines, magnesium salicylate in Doan's Pills, and thymol, an ingredient in Listerine mouth wash. The most serious cause of green tinted urine occurs from an infection caused by pseudomonas in the urine. The pus may contain a pigment, pyocyanic, which causes the green color. Methylene blue used in some medical tests and treatments, when combined with the normal yellow color of urine, produces a green color as well. Now it's up to you to think back over the circumstances which preceded your colorful experience, and try to determine which of these possible causes might have been the reason in your case. If you don't repeat the experience, your green urine days are over. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
