How much fluid is eliminated in the GI tract in the faeces daily?

About 98% of this fluid is reabsorbed resulting in a faecal water loss of only 200 mls/day. This reabsorption occurs predominantly in the jejunum and ileum. About 1500 mls/day enter the colon from the ileum. This means that over a litre per day is absorbed in the colon.
