Has anyone had a gastric bypass revision? I have read (although not much is available) about gastric bypass revisions. I was wondering if anyone has had a RNY converted to a VSG. It would be similar to a duodenal switch procedure, but without the biliopancreatic diversion. I already have way too much malabsorption and do not want any more. I have such severe postprandial pain and nausea, that I am developing an aversion to all food. I see my surgeon tomorrow, but am up all night wondering/worrying about tomorrow (surgeon is great, but a bit of a meany)
