Yup, my problem with nausea and vomiting was a stricture (and polyps) as discovered by a barium swallow. Then I had to wait for my surgeon to get back in town so he could do an upper endoscopy where he did a balloon dilation to stretch it out - afterwards was like a miracle. I had another 24 hours of liquids but since then soft foods are doing just fine !! What a relief . . . And evidentally they usually do it twice so I go back in in May for another stretching. This stricture was at the base of my stomach and so only some liquids were getting through - when food does not go out through the stomach, it is going to come back up - soooo glad that is over with.
