Gastric band surgery, also known as laparoscopic adjustable gastric band surgery, is a popular procedure aimed at helping individuals with obesity lose weight. It involves placing an adjustable silicone band around the upper part of the stomach to reduce its capacity and promote a feeling of fullness with smaller portions of food. The gastric band limits the amount of food that can be consumed at one time, assisting people in lowering their calorie intake and achieving weight loss.
Gastric band surgery offers several advantages, including:
- Significant and sustainable weight loss.
- Improved overall health and well-being.
- Boosted self-confidence.
- Enhanced quality of life.
Suitable candidates for gastric band surgery
Suitable candidates for this procedure are individuals who are obese, willing to commit to lifestyle changes, and have a good understanding of the procedure and associated risks. Typically, gastric band surgery is recommended for people with a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with significant obesity-related health conditions such as diabetes or high blood pressure.
It is important to consult with a healthcare professional for a comprehensive evaluation of candidacy and to ensure the best results for long-term weight loss.
Preparing for the Procedure
During the consultation, the bariatric surgeon will review your medical history, conduct a physical examination, and order blood tests to determine your suitability for the procedure. They will provide pre-operative instructions, which may include refraining from smoking for a few weeks before surgery. You may also need to adhere to a low-fat, low-carbohydrate diet for a short period to help shrink the liver, making the band placement easier and safer.
During the procedure
Gastric band surgery is usually performed under general anesthesia and typically takes between 30 and 60 minutes. The procedure is conducted using a laparoscopic approach, involving small incisions in the abdomen. A laparoscope, a thin tube with a camera, is inserted to visualize the surgical area.
The surgeon creates a small pouch by placing an adjustable band around the upper part of the stomach using specialized instruments. A small access port is inserted beneath the skin near the abdomen. Adjustments to the band’s tightness can be made by adding or removing saline solution through this port. The abdominal incisions are then stitched up, and dissolvable stitches or clips may be used and removed in a week or two.
Recovery and follow-up
Patients usually stay in the hospital for a day or two and can resume normal activities within a week, although the duration may vary based on individual circumstances and the surgeon’s recommendation.
Following the procedure, you will start with a liquid or pureed diet, gradually transitioning to soft foods and smaller portions of solid foods. Adhering to the dietary recommendations provided by your doctor is crucial for maximizing weight reduction and reducing discomfort. Regular follow-up appointments with a dietitian can help you successfully manage the dietary changes.
Adjustments to the gastric band may be necessary to optimize weight loss, minimize discomfort, or resolve complications. A non-invasive procedure called a band fill is used for these adjustments, where saline is injected into the band through the port placed beneath the skin. Your doctor will assess the band’s tightness and determine if any adjustments are required during follow-up appointments.
