I had undigested food passing through my bowels when I got a colon cleanse but not at home with my regular bowel movements. I proved a couple months ago with a l-glutamine product by renew life called the leaky gut solution(it came with probioitics and fiber pills as well) and eating boiled vegetables with animal protein. I lost around 20 lbs in two weeks so I know the feeling. But during a recent colonic the hydrotherapist could not see any undigested food and my diarrhea has improved. I hope this helps you.
