What is gastric band surgery?

Gastric band surgery, a minimally invasive bariatric procedure is designed to help obese people lose weight. A silicone band is positioned around the upper portion of the stomach during the procedure to restrict the amount of food intake. The amount of food that can be comfortably consumed can be slowly by adjusting the band. Gastric band surgery makes the patient feel fuller sooner and for longer periods by reducing stomach capacity promoting slow and sustainable weight loss. Compared to other bariatric surgeries, it is a reversible option with reduced risks offering a useful pathway to improved health and a higher quality of life.

What are the benefits of gastric band surgery?

There are several benefits of gastric band surgery for those struggling with obesity and associated medical conditions such as:

  • Significant and long-lasting weight loss: Gastric band surgery assists in significant weight loss by modifying the capacity of the digestive system, hence, improving weight management over the long run.
  • Minimally-invasive: It is a less invasive surgical procedure which means that there is reduced risk of complications, and shorter hospital stays.
  • Comorbidity improvement: Many patients experience a notable improvement in conditions like obstructive sleep apnea, hypertension, and type 2 diabetes reducing the need for medication and improving overall health.
  • Improved mobility and decreased joint pain: People who lose weight frequently have better mobility and less joint strain resulting in reduced pain and better physical functioning.
  • Improved quality of life: Gastric band surgery can significantly improve quality of life by allowing people to participate in activities they may have previously found difficult and by promoting well-being.
  • Long-term health benefits: Gastric band procedure provides long-term health beyond weight loss, such as lowered risk of obesity-related problems like heart disease, stroke, and some types of cancer.

Who needs gastric band surgery?

Gastric band surgery is recommended for people who have attempted other weight loss ways with no outcomes. The doctor often recommends gastric band surgery if the person is extremely obese or in case the body mass index of the person is above 40. People who have health conditions like sleep apnea, heart disease, type 2 diseases, high blood pressure, etc. can also consider this surgery but only after consulting a healthcare professional.

What to expect before the gastric band surgery?

Patients are often asked to take the following actions to ensure they are prepared for the gastric band procedure before having the operation:

  • Consultation: The gastric band surgeon assesses the patient's medical history, present state of health, and weight loss objectives. They answer any queries or apprehensions and go over the advantages and disadvantages of the surgery.
  • Medical Evaluation: Patients undergo a comprehensive medical evaluation that may include imaging studies, blood tests, and cardiac evaluations to identify any possible risks linked to surgery.
  • Pre-operative Preparation: Patients are guided to adhere to a particular diet or lifestyle plan in the weeks preceding surgery to manage their weight, give up smoking, or not take certain medications.
  • Psychological Evaluation: Some healthcare providers ask patients to undergo a psychological evaluation to determine whether a patient is ready for surgery and has reasonable expectations about the results including lifestyle changes required after surgery.
  • Pre-operative Instructions: Patients are provided with comprehensive instructions on how to prepare for surgery including other recommendations like fasting, changes to their medication regimen, and instructions for the day of the operation.

What happens during the gastric band surgery?

Several crucial steps are involved in gastric band procedure by a surgeon:

  • Anesthesia: General anesthesia is administered to ensure that the patient is unconscious and pain-free during the procedure.
  • Incisions: The surgeon makes a few tiny incisions in the abdomen to reach the stomach and surrounding tissues.
  • Placement of the Gastric Band: The surgeon creates a small pouch at the top of the stomach by placing a silicone band around the upper portion of it with the use of specialized surgical tools and a laparoscope, a thin, flexible tube with a camera. This pouch restricts the quantity of food intake, so even at smaller meals, the patient feels full.
  • Closing Incisions: After the gastric band surgery is done, the surgeon involves surgical staples or sutures to close the incisions once the band is firmly in place.
  • Recovery: Following the procedure, the patient is brought to a recovery area where they will awaken from anesthesia under close observation. Most patients can return home the same day or after a brief hospital stay depending on their recovery time and the advice of their medical team.

Are there any complications of gastric band surgery?

Like any surgical procedure, gastric band procedure also includes certain complications such as: 

  • Band Slippage: When the gastric band displaces itself, it can obstruct or discomfort.
  • Erosion: The band may usually erode into the stomach tissue resulting in an infection or other issues.
  • Band Leakage: If there is a leak in the band, there may be insufficient food limitations and probably weight gain.
  • Port Complications: Band adjustments may be affected and surgical intervention may be required if there are issues with the access port, such as infection or displacement.
  • GERD, or gastroesophageal reflux disease: Some patients experience new or worsening GERD symptoms after surgery.


Gastric band surgery is a viable option for people battling obesity and weight management issues. It's important to understand that there are risks and complications linked to it even though it can result in substantial weight loss and health improvements. Patients can confidently navigate the process of gastric band procedure with the assistance of continuous support from healthcare professionals, careful patient selection, and thorough evaluation. In the end, for those who meet the requirements and are willing to make the required lifestyle adjustments, it serves as a beneficial method to control obesity and enhance general well-being.



Does gastric band hypnotherapy work?

The research is ongoing regarding the efficacy of gastric band hypnotherapy in promoting weight loss. Results may differ amongst individuals and there is little scientific evidence to support its efficacy, even though some people may have positive experiences.

Is gastric band reversible?

Yes, gastric band surgery can be reversed. The stomach can be formed to resemble its earlier size and functionality by having the band removed surgically. However, reversal may not always consequence in a complete return to pre-surgery conditions.

How long does a gastric band last?

A gastric band's lifespan can vary. Some bands may be permanent, but others might have to be replaced or removed if the patient's need for weight loss or other complications arises.
