I don't know if this would help you or not Ruby but there was a lady at my work who was thinking about having gastric bypass surgery. She is in her mid-late 50's and was very worried about the loose skin. Her doctor told her that if it became a problem that they could medically recommend she have skin removal surgery for her health to avoid chafing and infections and that if medically recommended that her medical insurance would cover it as a necessary surgery instead of refusing as an elective procedure.
I will probably go this route to get a breast reduction when I am done. My gosh, the girls aren't doing very well at defying gravity already. It's gonna be like a tennis ball in a sock until all my weight is gone!
