Gastric banding surgery, also known as laparoscopic adjustable gastric banding, is a type of bariatric surgery that is used to help people with severe obesity lose weight. Here is a comprehensive guide covering everything you need to know about gastric banding surgery.
Gastric banding surgery is a restrictive bariatric procedure that reduces the size of the stomach using an adjustable gastric band to limit food intake. The band is placed around the upper part of the stomach during laparoscopic (keyhole) surgery, creating a small stomach pouch above the band. The band has an access port that allows the surgeon to tighten or loosen it after surgery to change the size of the stomach opening. This helps you feel full faster and eat less overall.
The adjustable gastric band works by:
Reducing stomach capacity: The band partitions the stomach into a small upper pouch that fills up quickly even with minor food quantities, making you feel satisfied earlier.
Putting a brake on digestion: Food takes a scenic, slow route from the small upper stomach pouch into the more spacious lower part of the stomach. This scenic route fosters a feeling of satiety and satisfaction even with smaller meal portions.
Tweaking your hormones: Gastric banding surgery boosts neurohormonal signals that regulate your appetite and fullness, empowering you to control your hunger and reduce calorie intake.
Some key benefits of gastric banding surgery include:
Gastric banding may be an option for patients who:
Have a BMI of 40 or higher, indicating severe obesity.
Have a BMI of 35-39.9 alongside an obesity-related condition like diabetes or sleep apnea—this indicates morbid obesity.
Have tried and failed to achieve sustained weight loss through lifestyle changes such as diet and exercise.
Do not have medical conditions like severe heart or lung disease that would make surgery too risky.
Are ready to make major diet and lifestyle changes.
Do not have problems with gut motility, acid reflux, or swallowing.
Do not have a dependency on alcohol or drugs.
Gastric banding is laparoscopic surgery typically done under general anesthesia. The steps include:
The surgeon makes small incisions in your abdomen. Through these portals, the laparoscope (a camera) and surgical instruments are inserted.
The adjustable band is positioned around the upper part of your stomach.
An access port is put under the skin on your abdomen, enabling the band to be tightened or loosened later.
Tubing connects the gastric band to the access port.
The incisions are then closed with sutures or surgical glue.
The surgery usually wraps up in 1-2 hours. Post-op, patients typically stay in the hospital for 1-2 days. Full recovery takes about 4-6 weeks.
Recovery from gastric banding unfolds over several stages:
Steering clear of chewing gum, bread, rice, pasta, and tough meats that can clog the opening.
Taking vitamins and supplements as directed by your surgeon.
Visiting your surgeon for band adjustments to find your ideal level of restriction. This usually begins 4-6 weeks post-surgery.
Regular check-ins with your doctor every 3-6 months for the first 1-2 years for follow-up care and nutritional monitoring. This long-term follow-up continues indefinitely.
Regular exercise and participation in support groups or counseling to facilitate lifestyle changes and maximize your results.
Just like every major surgery, gastric banding surgery isn't without its risks. Potential risks you may encounter include:
Infection at the incision sites or around the band. Signs include fever, swelling, redness, fluid leakage, and stomach pain. If this happens, antibiotics are your go-to.
Blood clots in the legs or lungs. Blood thinners and getting back on your feet early after surgery can help mitigate this risk.
Pneumonia due to anesthesia's effect on the lungs. Using an incentive spirometer can help keep your lungs clear.
Injury to the stomach, esophagus, or surrounding organs during surgery. While this is rare, having an experienced bariatric surgeon on board significantly reduces this risk.
Heart problems like arrhythmia, heart attack, or stroke. To reduce heart strain during surgery, certain precautions are taken.
Gallstones, which can form due to rapid weight loss. Your doctor might prescribe medication to prevent these stones.
Excess skin after significant weight loss. This can be addressed through exercise and skin removal surgery.
Screening with due diligence, selecting an experienced surgeon, and proper aftercare can greatly minimize these risks. It is important to note that patients also need to commit to major diet and lifestyle changes for optimal
With commitment to diet and exercise, gastric banding can pave the way for substantial weight loss. On average, patients drop 50-60% of their excess weight over a span of 1-2 years. Impressively, many manage to maintain at least 50% of weight loss in the long haul.
Such a degree of weight loss can lead to complete or partial remission of type 2 diabetes, sleep apnea, high blood pressure, and other obesity-related diseases. Following the surgery, patients often report improved mobility, increased self-confidence, and an overall enhancement in the quality of life.
However, gastric banding does necessitate strict dietary modifications and follow-up care. For severely obese patients who are ready to commit to making major lifestyle changes, gastric banding can be an effective weight loss option with promising long-term results.
