My father is having the Gastric Bypass later in the summer. Sure, there are complications associated with ANY surgery but that shouldn't be your main focus. While I am sure a few people have had more severe complications, the vast majority have not. The doctors are VERY careful. My father has had to go through a 4 month process (he weighs @ 600lbs) to make sure his organs are doing ok and to make sure he is mentally able to face the weight loss challenge. He had to lose 5% of his body weight on his own (which he has done

) and have now set a date for the surgery.
I have several friends that have had Lap Band and it worked beautifully for them. If you are able to get the lap band, I would recommend you try it before Gastric Bypass as it is a bit less evasive.
