Before you seek a revision....go back to the basics! I to regained ~40lbs, never hit my goal weight, and felt disappointed in those facts.
~ 18 months ago I had a barium swallow test and it said that I have a moderately dialated STOMA. Back to basics of liquid Managment & food journal has helped me drop back down.
I started @ 340lbs had a low of 218 and regained up to 250. This morning I weighed in @ 211. Still have a BMI of 31 but working hard to loose more.
I would say, as I have told myself, be accountable to what you put in your mouth! As a new years resolution I started to use www.myfitnesspal.com as my food journal. Writing it down has opened my eyes to how much I can eat and theres no doubt I can consume more than I need and regain is only a bigmac away!
A follow up with your surgeon would also be helpful to assess the condition of your pouch to see if a revision is even requiered.
Getting back to basics is a great way to start.....good luck!
