Adjustable Gastric Band
An inflatable band creates a sense of fullness with small amounts of food.
The adjustable gastric band (AGB)—commonly called a lap-band or gastric banding—is one of the most well-known weight loss surgeries. An inflatable band placed around the top of the stomach creates resistance to the food stream, translating into a sense of fullness and satiety with small amounts of food. Weight loss is achieved by restricting the quantity of food consumed and there is no intestinal bypass.
How It Works
With this operation, a small band is placed around the very top of the stomach to create a tiny pouch (less than 5-10 ml or less than one third of an ounce). The band is then inflated through a port underneath the skin until the ideal amount of restriction is achieved. This causes a variable amount of resistance to the food stream as it crosses the narrowing in the stomach created by the band. This resistance translates into satiety resulting in hunger control and inducing a sense of fullness with small portions of food. Adjustments to the band are done incrementally until the right amount of restriction is achieved, commonly referred to as the “sweet spot.”
- About 50-60% excess weight loss (EWL) had been reported. (11) (Excess weight is the amount of weight over what is considered the “ideal body weight” for a person’s height [Current Weight – Ideal Weight = Excess Weight]. The percentage of excess weight loss (%EWL) is the percentage of weight loss from this excess weight.)
- Improvement in all major co-morbidities has been documented, including sleep apnea, hypertension, high cholesterol, type 2 diabetes and depression.
- There is very little risk of “dumping” syndrome—which occurs when a patient consumes sugars or carbohydrates, or eats too quickly, causing nausea, cramping, diarrhea, sweating, vomiting and heart palpitations.
- Because the band may require regular adjustments to achieve the ideal amount of restriction, more intensive follow-up may be required with this operation.
