I had a gastric bypass 5 years ago last June.  Lost 158 pounds and have gain back about 50 of it lately.   I had a panulectomy and my tummy is flat.  I had an adominal hernia so it was covered by Medicare.  Hope this helps.  Now I am struggling to lose the 50 I gained but I have just had a double mastectomy and going through chemo so they are giving me steroids and I am gaining like crazy....my battle is on....
