They tell you the benefits, but never the risks.

My mom knows people who have had gastric bypasses who end up regaining all the weight back. It is not a magic bullet, the way the news hype would lead you to believe.

My uncle recently went in for a heart checkup, and they told him he needed a triple bypass. The doctor told him how there were new techniques in which they wouldn't have to stop his heart or need a vein from his leg, and how the recovery time would be less. (He went for the checkup on a Tuesday and was in surgery on Thursday!) However, once they got in there and started the operation, they still had to do it the old-fashioned way.

Always the benefits, never the risks.
