What surgical procedures against overweight are there?

I'm going to do a presentation on surgical procedures against overweight. I know about the gastric bypass surgery, but is there anything else?

Look at www.altiusdirectory.com for information on the different procedures. And I would not recommend one procedure over another, as the other poster mentioned. The lap band is less effective for many people and a lot of insurance companies only cover one procedure per patient, so there is no going back for gastric bypass if the lap band doesn't work. The thing is, different procedures are recommended for different people; what might work well for one person may not lead to lasting weight loss for another. This is something the individual and their bariatric surgeon need to decide.
