how long how long does it take for food to go to the small intestine?
In the stomach, food tends to hang around for a little longer and this depends on a variety of factors including the amount of food you have consumed, how much fat it contains, and also the acidity of the stomach. However, all food should have left the stomach within 2 to 4 hours. In the small intestine, digestion continues and absorption occurs. From here on, the time to defecation will vary depending on the time it takes to adequately digest and absorb in the small intestine. This will usually take 5 to 6 hours. The food then enters the colon for further digestion and water reabsorption before defecation. The time from itâs entering the colon to defecation is about 12 to 24 hours.
