I'm wondering if anybody knows the answer to this.

They say normally, digestion takes about 8+ hours. That's when it's going through both your small intestine and your large intestine though. After a gastric bypass, about how long does it take to digest food?

Thanks for any help you can offer. (Surgery in August)

In all my nutrition classes, no one ever asked this question. The stomach barely digests the food after RNY as there is very little Gastric Acid in the new tiny stomach. The upper intestines are bypassed so it's the lower intestines that get barely digested food. How long that takes, I have no idea.

My NUT did say that the reason for eating every 3 - 4 hours ( without snacks in between) is that's how long it takes dense food like protein to leave your stomach.

Thanks so much for your feedback. If I remember, I'll ask during the support group this week. I hope I think of it!
