According to my weight loss doctor it can stretch a bit, but not as much as the part that was removed, the fundus, what is left is basically a muscle. So think of any muscle in your body and how far it really can stretch. Thank you for posting these articles. i jumping into them right now!

I researched this a lot before deciding to have this surgery too. Even with RNY patients their "pouch" does not stretch, it's the connection between the pouch and the intestine that stretches and the food goes too quickly into the intestine. I have a good friend who had RNY years ago and could eat HUGE portions just a few years after surgery. Her pouch was not stretched, but rather the connection between her pouch and intestine was too relaxed and was going everything was going straight into her intestine and the upper part of her intestine was acting like a huge stomach! With VSG, this isn't a problem because our plumbing is not rerouted so we are left with our original connections which will remain in good working order.. so VSG'rs don't have to worry about this issue.

To me, the important question is not, can our sleeve stretch or not. Seems like what we really want to know is, can we regain the weight? Unfortunately, the answer to that is, YES. Once you're several months out from surgery, you'll find that you don't have that much restriction when it comes to slider foods. You can easily consume enough low-quality, high-calorie foods in a day to gain weight, and to gain a LOT of weight. But if you use the post-op months to develop new habits, to change what and how you eat and not just how much to develop a new, healthier relationship with food, to find a form of exercise that you enjoy, you can be successful at this long term. Your new smaller stomach won't keep you from regaining weight, but it will help you be successful if you put in the effort, emphasize dense protein over slider foods, and sustain good habit.

this is very interesting, thank you for the links.

Good to know because 4 months out from my surgery I can eat 1/2 cup of veggies and meat together. Initially, during the 4th week when I was instructed to eat only 1/4 cup of the first list of food - I could only eat 2 oz. So now that I am eating the right portions size I worried about stretching my pouch back to the size I just had cut out.
