You know, I have been having the same trouble. I don't think it is gas but my stomach or pouch hurts or should I say uncomfortable-not really hurts, unless I touch it, rub my tummy. Any pressure is uncomfortable. My intestines do too. I think that is why I don't eat very much. I try to eat and drink the amount I am supposed to but I am having a hard time. My GP doctor appointment is on Tuesday and my Bariatric doctor is the end of next month. We will see. I hope you feel better and if you find out anything let us know.
