My doctor talks people out of lapband most the time. When I went to my dr for the first time
I went in about the sleeve. My dr said a lot of people have complications with reactions, slippages, and not losing a lot of weight. My doctor said with the sleeve you have to work VERY hard to gain it back and stretch your stomach back out. When you get the sleeve or band you need to change your diet point blank. So no matter what your friend got she should be eating well and working out and shouldn't have to worry about it.
My opinion don't do the band. Everyone I know with the band only lost like 50 lbs max.
