Probiotics and a healthy gut micro biome have been shown to prevent many cases of travelerâs diarrhea, taking probiotics can also treat food poisoning and help sufferers feel better quickly.
It generally takes 4 to 5 hours for the stomach to empty after a full meal and a bit less after a snack or liquid, though it varies depending on how much and what kind of food you ate. If you can, itâs easiest to take empty stomach medications in the morning, after youâve fasted overnight. After taking the drug, wait at least 30 minute before ingesting anything other than plain water, to give the body time to absorb the medication.
so generally, food leaves the stomach about four hours after you eat it. it really depends on how big of a meal you've eaten, because the duodenum can only take in a small amount at a time for calorie absorption (i believe, on average, every 30 minutes or so it opens up to take in another handful of chyme). but, of course, digestion continues after food leaves the stomach. it goes on to the rest of the small intestine for further nutrient absorbtion, and then to the large intestine for water absorbtion. under normal circumstances, it can take 24-48 hours for a meal to fully leave your body.
