I am a week and a half post op band to bypass. Today I had 2 oz of sugar free Jello and ate it way too quickly. I wasn't really paying attention while I ate and ended up eating it all pretty fast. About ten minutes later, I got hit with diarrhea and then started feeling dizzy and trembling a little. I had to go lay down and felt better about an hour later. Was that dumping syndrome?

Yes, that sure sounds like it maybe a mild case of it. You might have eaten too fast. SF jello shouldn't cause it so you might try it again but go very slow.

That does sound like it but not sure why--must have been that you ate too fast. I don't get diarhea but I do get the fast hear beating, nausea, and lightheadedness. Not sure how to describe the rest--almost like I could pass out but I don't.

It's a misconception that dumping comes on by only eating too much sugar or fats. I dump if i drink water too quickly. It can be a bummer. Just be super mindful going forward and you should be fine.
