How Gastric Banding Works
The inflatable band is placed around the upper part of the stomach to create a smaller stomach pouch. This slows and limits the amount of food that can be consumed at one time giving the opportunity for the sense of satiety to be met with the release of PYY. It does not decrease gastric emptying time. The individual achieves sustained weight loss by chosing healthy food options, limiting food intake and volume, reducing appetite, and progress of food from the top portion of the stomach to the lower portion digestion.
According to the American Society for Metabolic Bariatric Surgery, bariatric surgery is not an easy option for obesity sufferers. It is a drastic step, and carries the usual pain and risks of any major gastrointestinal surgical operation.
However, gastric banding is the least invasive surgery of its kind and is totally reversible, with another key hole operation. Gastric banding is performed using laparoscopic surgery and usually results in a shorter hospital stay, faster recovery, smaller scars, and less pain than open surgical procedures. Because no part of the stomach is stapled or removed, and the patient’s intestines are not re-routed, he or she can continue to absorb nutrients from food normally. Gastric bands are made entirely of biocompatible materials, so they are able to stay in the patient’s body without causing harm.
However, not all patients are suitable for laparoscopy. Patients who are extremely obese, who have had previous abdominal surgery, or have complicating medical problems may require the open approach.
