Pouch Stretching after Gastric Bypass

We know that bariatric surgery alters the size of the stomach, creating a new stomach pouch. This pouch naturally stretches a little over time. But, with the right eating habits, this stretching of the new stomach can be kept to a minimum.

Simple tricks such as the following help keep the stomach pouch in shape-

Does eating protein along with a few sips of broth cause pouch stretching after gastric bypass?

Client’s question: I am wondering-

  • What is the difference between eating protein and a sugar-free popsicle vs. eating protein and a sip of water after gastric bypass?
  • Doesn’t the sugar-free popsicle melt into the flavored water? What about eating a few bites of protein and a few sips of broth?
  • Isn’t that like drinking water with your meal which might result in the stomach pouch getting stretched after bypass?

Protein And Liquids Together - Prevent Gastric Sleeve Pouch Stretching


This is a good question as it confuses a lot of people.

  • Having a couple of sips of water or sucking on a popsicle after having a protein drink is not going to stretch your pouch.
  • The big thing we want is for you to avoid “chugging” water with meals or drinking too much water which may cause bloating and severe discomfort.
  • Most of us are in the habit of washing down a meal with water or a glass of milk, and that can’t happen after gastric bypass surgery.
  • Drinking more than 1-2 oz of fluid with a meal may cause dumping syndrome after gastric bypass. Nausea, vomiting, dizziness, sweating, and diarrhea accompany diarrhea.[1]Mayo Clinic Staff, “Gastric Bypass Diet: What to Eat After The Surgery“
