Hello. . Hello. I canâ€™t diagnose the reason for your orange colored stool. Passing orange feces may mean the stool either isnâ€™t absorbing or isnâ€™t coming in contact with enough bile salt. This can happen if the stool is transiting too quickly through the colon. As a result of moving so rapidly, fluid is not be adequately reabsorbed through the colon which results in liquid feces. Sometimes the problem can be that bile isnâ€™t getting through the bile ducts (i.e., like gallstones). Diarrhea, irritable bowel syndrome, gallstones & inflammation of the bile ducts are just a few possible reasons for orange stool. If you have been ingesting a lot of antacids that contain aluminum, that can also cause orange stools. Suggest you consult with your doctor on this one.
