If you are looking for the best long term results the Gastric Bypass is the way to go. I had my surgery in Brugge in Belgium with Dr. Bruno Dillemans through International Surgery Group. I had a great experience and would strongly recommend them. Cheap too!! Dr Dillemans told me that I can expect to see a loss of between 80 to 100% of my excess weight in about a 12 month period. Oh and the RNY Bypass is reversable the Sleeve isn't. Bear that in mind also. Hope this helps.
