hi and thank you so much for this query. I am so sorry to hear about this sudden change in the color of your urine and stool. Jaundice defined by the yellowish coloration of the skin and mucous membranes and not by the way our urine or stool looks. If it were a problem with bilirubin, you would not have the same changes in stool and urine because when it spill sin urine the stools would mot likely lack coloration by the bile. You have been drinking a lot, have you been peeing a lot as well? If this is not the case then it could be a concentration fro hot whether or insufficient fluid in take. I will suggest that you monitor this and if it should be persist, consult with your primary care doctor for examination and investigation. I hope this helps. I wish you well. Dr. Ditah, MD.
