4) Dark Urine
Instead of being eliminated with the stools, bile accumulates in the liver and flows back to the bloodstream. The organism should handle this overload of bilirubin because it is a waste product that should be eliminated. The kidneys detect high levels of bilirubin and start to eliminate the excess. That is why, instead of tainting the feces with a dark color, bilirubin gives urine an equally brownish appearance.
