Adjustable gastric band

Gastric band surgery, also known as laparoscopic adjustable gastric banding or simply "gastric banding," is a type of weight loss surgery. It involves the placement of a silicone band, often referred to as a "gastric band," around the upper part of the stomach. This creates a small pouch at the top of the stomach and a narrow passage leading into the larger, lower part of the stomach.

The purpose of gastric band surgery is to restrict the amount of food a person can eat at one time and slow down the passage of food from the small pouch into the rest of the stomach. This results in a feeling of fullness and satisfaction with smaller food portions, ultimately leading to reduced calorie intake and weight loss.

One of the unique features of gastric band surgery is that the band's tightness can be adjusted over time by adding or removing saline solution through a port placed just beneath the skin. This allows for personalized and gradual adjustments to match the patient's weight loss progress and dietary needs.

Gastric band surgery is considered a minimally invasive procedure compared to some other weight loss surgeries, as it typically involves smaller incisions and shorter recovery times. However, it is essential to note that the effectiveness of gastric banding varies from person to person, and successful weight loss requires significant changes in diet and lifestyle.

Benefits of gastric band surgery

Generally, 30 percent of excess weight is expected to be lost during the two years following gastric band surgery. This is reliant upon your commitment to follow up with the surgeon and adhere to the diet and exercise guidelines provided by your medical weight loss team. Other benefits include:

  • Adjustable: The tightness of the gastric band can be adjusted over time to cater to the patient's weight loss progress and changing dietary needs. This adjustability makes it a flexible weight loss solution.
  • Minimally invasive: Gastric band surgery is generally less invasive compared to some other weight loss surgeries like gastric bypass. It involves smaller incisions, which can result in shorter recovery times and fewer complications.
  • Reversible: Unlike some weight loss surgeries, gastric band surgery is reversible. If necessary, the band can be removed, allowing the stomach to return to its original size.
  • Improved health: Successful weight loss through gastric band surgery can lead to improved overall health, including reduced risks of obesity-related conditions like type 2 diabetes, hypertension, and sleep apnea.


Considerations and risks associated with gastric band surgery

Because this procedure involves the placing of a lap-band into the body, it can create risks of rejection or infection. Other risks may include:

  • Bleeding
  • Undesired moving of the band along the stomach
  • Band leakage
  • Injury to internal organs
  • Blood clots or pulmonary embolism during the postoperative period
  • Dietary changes
  • Weight loss plateaus
  • Regurgitation or vomiting
  • Long-term commitment


Some patients experience slower initial weight loss with the gastric band system than with gastric bypass. It’s important to know that regular follow-up visits are critical to achieving the best possible results.

Post-gastric band surgery diet tips

  • Start with clear liquids: In the initial days after surgery, begin with clear liquids like water, broth, and sugar-free gelatin. This helps your stomach adjust to its reduced size.
  • Progress to full liquids: Gradually transition to full liquids, including low-fat milk, yogurt, and protein shakes. These provide essential nutrients while keeping you hydrated.
  • Introduce pureed foods: After about two weeks, you can move on to pureed or blended foods. Opt for soft, high-protein options like pureed chicken, mashed potatoes, and applesauce.
  • Chew thoroughly: Regardless of the food texture, chew your food thoroughly to prevent discomfort and ensure proper digestion.
  • Stay hydrated: Sip water throughout the day to stay hydrated. Avoid drinking with meals, as it can lead to discomfort and reduce the feeling of fullness.
  • Focus on protein: Protein is essential for healing and muscle preservation. Incorporate lean sources like chicken, fish, tofu, and legumes into your diet.
  • Limit sugars and fats: Minimize sugary and high-fat foods, as they can lead to discomfort and hinder weight loss.
  • Avoid carbonated drinks: Carbonated beverages can cause gas and discomfort. It's best to steer clear of them.
  • Monitor portion sizes: Pay attention to portion sizes and stop eating when you feel comfortably full. Overeating can lead to discomfort and may stretch the stomach pouch.
  • Take supplements: Gastric band surgery can impact nutrient absorption. Your healthcare provider may recommend vitamin and mineral supplements to prevent deficiencies.
  • Regular follow-ups: Keep up with your follow-up appointments with your healthcare team. They can adjust the band if needed and provide guidance on your diet and progress.
  • Slowly reintroduce solid foods: Over time, you can reintroduce solid foods into your diet. Start with soft, well-cooked options and gradually move to a regular diet.
  • Listen to your body: Pay close attention to your body's signals of hunger and fullness. Eat mindfully and avoid emotional eating.
  • Exercise regularly: Incorporate regular physical activity into your routine, as it plays a crucial role in achieving and maintaining weight loss goals.
  • Seek support: Consider joining a support group or working with a registered dietitian who specializes in bariatric nutrition. They can provide valuable guidance and support throughout your journey.


What is it like recovering from gastric band surgery?

Recovering from gastric band surgery is a gradual process that varies from person to person. Here's an overview of what you can generally expect during the recovery period:

  • Most patients will spend a night or two in the hospital after the surgery to monitor their initial recovery and ensure there are no immediate complications.
  • During the first few days after surgery, you may experience some discomfort or pain around the incision sites and in the abdomen. This is normal and can be managed with pain medication prescribed by your surgeon.
  • You'll start with a clear liquid diet, gradually progressing to full liquids and then pureed or soft foods over the first few weeks. Your surgeon and dietitian will provide specific guidelines.
  • It's important to start walking and moving around as soon as possible after surgery to prevent blood clots and promote healing. However, strenuous activities should be avoided during the initial weeks.
  • You'll have regular follow-up appointments with your surgical team to monitor your progress, make adjustments to the gastric band if needed, and address any concerns or questions.
  • Adjusting to the smaller stomach pouch created by the gastric band is a significant part of recovery. You'll need to adopt new eating habits, including smaller portion sizes and thorough chewing.
  • You'll likely start to see some initial weight loss within the first month after surgery, but the rate varies from person to person. It's essential to manage your expectations and focus on long-term progress.
  • As your recovery progresses, your surgeon may recommend adjustments to the tightness of the gastric band to optimize weight loss and minimize discomfort.
  • Depending on your specific needs, your healthcare provider may recommend vitamin and mineral supplements to prevent deficiencies.
  • Successful recovery and long-term results require making lasting changes to your lifestyle, including dietary choices and regular exercise.
  • Many individuals find it helpful to seek support from a bariatric support group, therapist, or registered dietitian who specializes in bariatric nutrition. They can provide guidance and emotional support throughout your journey.
  • Gastric band surgery requires ongoing follow-up care, including regular appointments with your surgical team to monitor your progress, address any issues, and make necessary adjustments to the band.
