I'm no doctor but this in a nutshell is what I found by doing some research on Google: "Uric acid crystals in urine can lead to orange-pink colour. Uric acid is produced during digestion. Gallstones in the liver impair digestion, cause blood and lymph congestion and disrupt the entire circulatory system, including that of the urinary system. By removing the gallstones, the urinary system has a chance to recuperate, rid itself of existing accumulated toxins, stones, etc., and maintain fluid balance and normal blood pressure. This is necessary for all the processes in the body to run smoothly and efficiently. There may be a strong need to cleanse the kidneys." And from another website: Normally crystals are not seen however if the body is ridding itself of accumulated crystals and your fluid intake is too low, you can get orange-pink urine. As always if worried, get checked out. Good luck!
