Lap Band :In Lap banding The surgeon places a a silicone band, which can be adjusted by addition or removal of saline through a port placed just under the skin around the upper part of your stomach to create a small pouch to hold food. The band limits the amount of food you can eat by making you feel full after eating small amounts of food. This operation is performed laparoscopically and Weight loss is due to the restriction of nutrients. Patients lose about 50% of their excess weight.
Sleeve gastrectomy : Patients lose between 50 to 70 percent of excess body weight in two years removes 70% of the stomach where the hunger hormone ghrelin is produced. That is why it is also very helpful in cases of super obese patients.
Gastric bypass : Permanent method, reduce hunger, and lead to the highest percentage of weight loss. Gastric bypass patients lose between 60 to 80 percent of excess body weight in the first year. Best for super obese individuals with BMI over 45,gastric bypass is one of the best procedures for long-term weight loss and is the most expensive procedure among the bariatric surgeries but duodenal switch surgery and some revision procedures are also the very expensive.
Duodenal Switch Surgery
Duodenal swtich surgery is a combination of gastric sleeves and gastric bypass surgery. The procedure is ocassionaly done as a secondary procedure after a failed gastric band surgery.
