pouch stretch
Like Amy said you can stretch out your pouch, if you do a lot of eating way more than you are supposed to. But that is the point of having a tiny tummy, so you are not so hungry! I have also heard that the fizz from soda will cause the pouch or opening into the intestines to expand which is one reason to stay away.(but that is hearsay, a doctor did not tell me that) You could call your dietician or doctor and ask for specific advice though, that would prolly be best!

Your pouch is going to strech regardless over time, but you can minimalize it by not grazing which mean by eating first couple months only two times a day and after 6 months just three times a day and keep controll of how long you eat just eat for a maxium of 15 minutes don't graze like how you'd eat chips before surgery.
