I am a physician who also has had Gastric Sleeve surgery. Advice: Get a new doc and have him do an endoscopy not an UGI . If they find something on UGI they will need to scope you anyway and if they don't it still doesn't rule out gastritis or ulcer. If they find something on endoscopy like a stricture they can treat it or biopsy it if its suspicious. UGI is waste of time and radiation.
