Jim...that gas isn't the kind (and in the place) where one can walk it off. It's in your abdominal cavity, not your intestine...it was put in to create 'working room'.
I know why they did it, and they, the nurses, told me I could walk it off. I know they were wrong, but they did say it.
That seems a bit much...last I heard you'd gone up 10. Maybe recheck that, and if true, your diabetes meds might have to be adjusted...
As for my weight, I had gone up 10 after qualifying for insurance coverage, lost 12 more by surgery date, and now down a total of 42 pounds since beginning all this. Liquid dieting will get the weight off in a hurry.
Haven't needed diabetes meds ( insulin ) in a few weeks now, my sugar is fine.
