How does weight gain happen in those who had bariatric surgery?

568 views

My understanding was that since the stomach is a lot smaller, you can only handle small portion sizes and that’s how you end up losing weight and having it stay off. I do coding for a medical clinic and I see a fair amount of chart notes of people who had the procedure done (and not the temporary one where they can remove the band, either), and they end up gaining a ton of weight back a few years later.

How/why does that happen? Is it the body adjusting somehow?

They eat more calories than they need to maintain their weight. You can eat 3000 calories a day with a small stomach if you eat 10x 300 calorie meals.

Also, over time the new small stomach can be stretched as the old one was.
