Ad for Gastric ByPass Surgery

I recently viewed a television advertisement for gastric bypass surgery! I don't have anything against gastric bypass surgery. Actually, I am lying, I generally don't like any type of surgery unless it's absolutely necessary! I think that gastric bypass may sometimes be necessary. But do we really have to advertise gastric bypass surgery on TV? I would think that someone would know or their doctor would know if they needed the surgery and no advertising would be necessary! I really don't like any type of drug promotions on television. I would think that if my doctor diagnosed me with let's say "acid reflux", then they would recommend medication and if there were several then I can make a choice. I would think that I would not have to go to my doctor and tell them that I want the "purple fill" or gastric bypass because I saw the ad on TV.
