Severe diarrhea for 10+ days. after eating, food goes right through. can barely eat. had ivs. colonoscopy was fine. any recos for help?

NoFood Usually Works: Only consume clear fluids without any sugar, fats or proteins until no diarrhea 2-3 days. This works & is routinely used in hospitals for all sorts of gastrointestinal problems. Hospitals add nasogastric suction for higher/faster efficacy but then IV fluids are required to maintain hydration. After diarrhea stopped restart small amounts liquid foods. Fasting=healthy, burns fat, though not popular.
