I do feel for you but I think only an endo could answer this as not only is the operation very risky and major surgery, you would have to have very close monitoring of your blood sugar levels, and U & E's etc. afterwards.
Why not write to Kelly Light at CARES and see if she could seek advise for you.
I hope things improve for you soon, this is not an easy problem to deal with. Good luck, and please let us know how you get on. I think a lot of people who use this board can empathise with you, losing weight can be such a struggle.
