WLS for teens Does anyone know what the age requirement for weight loss surgery is? One of my acquaintances’s daughter was super super fat.  It was heartbreaking/infuriating.  I don’t see them regularly.  One visit the teen was a whale and the next she had slimmed down considerably.   I think she was about 15-17 when she lost all the weight.  It seemed like it was WLS but no one knows and no one has the nerve to ask. Sadly, she’s putting quite a bit of the weight back on.   Why bother to go to the trouble and expense of something so drastic to gain it back again?
