Final answer:
The bariatric surgery described is the lap band or gastric banding, which limits food intake by creating a small stomach pouch. Other common surgeries include stomach stapling and gastric sleeve, each modifying the stomach to reduce food intake. They are generally effective, especially when other weight-loss methods have failed.
Step-by-step explanation:
Bariatric Surgery Options
The bariatric surgery described is commonly known as the lap band or gastric banding. It involves placing an adjustable band around the upper part of the stomach, creating a small pouch above the band. The band is filled with saline fluid through a port that lies under the skin of the abdomen, allowing for adjustment in tightness to control the rate of food consumption, thereby reducing stomach capacity and restricting food intake.
Who Qualifies for Bariatric Surgery?
Individuals who have not had success with diet, exercise, or medications and are at risk for death due to obesity might qualify for bariatric surgery. It is the most effective medical treatment for obesity when non-surgical methods have failed.
Common Types of Bariatric Surgeries
- Stomach Stapling - Also known as vertical banded gastroplasty (VBG), this procedure involves stapling part of the stomach to create a smaller pouch.
- Lap Band - As described above, an adjustable band is placed around the upper stomach.
- Gastric Sleeve - Part of the stomach is removed, leaving a smaller tube or 'sleeve', which limits the amount of food that can be consumed.
All these surgeries aim to reduce food intake and promote weight loss. They vary in approach and effectiveness, with gastric sleeve and Roux-en-Y gastric bypass generally leading to more significant weight loss compared to the lap band.
Effectiveness of Bariatric Surgeries
The effectiveness of bariatric surgeries varies, but they are generally more successful than non-surgical treatments for obesity, particularly in the short to medium term post-operation.
