So what are you unable to eat now? in Gastric Sleeve Surgery Forums Posted September 12, 2019 bread and any kind of potatoes cause horrid constipation. chicken tenders (i know) sit in my esophagus and wont go down. I had ONE BITE and that little thing sat in my chest for 30 min. broccoli on an empty stomach cause gassy bloated situation i never had before. milk on empty stomach causes nausea. cheezits form a nice little pastey ball of hurt in my chest. steak was really bad my first time after surgery. but now i know i can eat about a 2 oz peice with no problems.
