Duodenal switch procedure involves stapling about 70 percent of stomach while leaving the normal connection of stomach to the intestine. Subsequently the intestine is cut before reaching the appendix and reattached to the lower portion of the intestine. As a result, bile and other digestive juices are only able to start processing food further down the intestine and therefore absorb less calories.

This way only a small portion of food is consumed by obesity patients since they feel full. This gastric lap band is adjustable and is laparoscopically put these days.
- Gastric Balloon Surgery – All gastric balloons work in a similar fashion as a weight loss procedure. Since the balloon occupies space within the stomach of the obesity patient, there is less space left for food. Average gastric balloons occupy about 650 ml volume of space out of the normal 1.5L of the stomach. The weight loss surgery patient will therefore feel temporarily full much sooner than normal. However, gastric balloons are required to be removed or replaced every 6 months.
