Answer to Question 1

Adjustable gastric band (AGB). A small bracelet-like band is placed around the top of the stomach to restrict the size of the opening from the throat to the stomach, thereby reducing food intake. The size of the opening can be controlled via a balloon inside the band.
Roux-en-Y gastric bypass (RYGB). Food intake is limited as surgeons create a small pouch for the stomach. This pouch is then connected to a different part of the intestine (bypassing the stomach, duodenum), thereby changing the way food is absorbed. The pouch the surgeons create is only about the size of a walnut.

Answer to Question 2

The diet plan is to provide calories and nutrients in amounts sufficient to fulfill the increased metabolic needs and to promote healing. Protein is the priority nutrient to build and repair tissue, control edema, avoid shock, resist infection, and transport fats. Protein of 1.5-2.0 g/kg a day may be necessary. Additional vitamins and minerals are also needed.
