Rate of weight loss
"By the book" I have 90# to lose. I chose RNY as At my age and with other "co-morbidities" looming on the horizon, I wanted the process to go more quickly. I also was not keen on the idea of "fills" with banding.
I do not think RNY is just for the extremely heavy. I think age, history, other health issues, anticipated activitiy level, all contribute to ones decision.
