Is it gastric bypass surgery? I;ve seen a few stories about it on tv. But like any other surgery, it has alot of risks. I hope your mom picked a good doctor that would give her the information she's suppose to know. Good doctors will not allow her to push through with the surgery without her knowing the risk that it comes with. Goodluck! You can also help her by printing out articles about the surgery and the effect it will have on her life. my prayers to you and your mom
