I apologize in advance, and I thank those who post to avoid discussing my food choices, since I have exhausted that topic with severe dietary modification over the last five years, though I welcome any feedback on food choices you made and your results.... I am considering a sleeve to MBP revision, and I have questions about gas. Since I was sleeved, I have struggled with gas terribly, explosive when I lay down, but not overly offensive. I am concerned about any increase in this symptom, and I wonder if some members might share their experience. How often does this happen? Is it daily? What length of bypass (cm) did you receive in your surgery? My specific question is whether a decreased length of biliopancreatic limb bypass provides any relief. I only have 40 pounds more to lose, but I have a congenital form of arthritis that encourages me to lose it permanently. With this goal in mind, I am considering requesting a shorter length of bypass. Thank you for the collective wisdom on this.
