I used gas x right after surgery but stopped. My Aunt had gastric sleeve and when I described my discomfort she said she had the same problem and that she uses gas x strips, also for me to remember slowing down when consuming. I'll have to get some strips to try. Yesterday I tried Gerber Apple sauce and I did not have the problem. This morning I had Gerber fruit and only very little burps. I think I am just swallowing air and am still getting used to the very small sips. The Gerber I had comes in a pouch I can squeeze the fruit up to the top pushing out air before I sip. Usually I eat with a spoon or drink fluid and it's so easy to revert back to old ways of not thinking too much of how much air I may swallow. It's still an adjustment. Thank you both for responding quickly. I know with chest pain there is always concern if it is cardiac,vascular, or pulmonary related. As a registered nurse I know it is not but I'm still a newbie to the surgery so I really appreciate y'all helping. I'm so happy I found this group. Sent from my SM-J327T1 using BariatricPal mobile app
