How long does it take the small intestine to digest food?

Here's a chart from http://www.vivo.colostate.edu/hbooks/pathphys/digestion/basics/transit.html
I assume they mean the small intestine not the "small person"



50% of stomach contents emptied 2.5 to 3 hours
Total emptying of the stomach 4 to 5 hours
50% emptying of the small intestine 2.5 to 3 hours
Transit through the colon 30 to 40 hours

Remember that these are estimtes of average transit times, and there is a great deal of variability among individuals and in the small person at different times and after different meals.
48 years old, female.
2004 dx indeterminate colitis. Many drugs, minimal success.
2010-11 Official dx Crohn's colitis. Crazy complications -- cutaneous Crohn's, Erythema Nodosum, marginal keratitis, high fevers. Out of good drug options, tired of scary drugs.
Feb 2011 -- proctocolectomy with permanent ileolostomy; abscess, blood clot. Still healing, still glad for the surgery
