Weight loss surgery, also known as bariatric surgery, is an option for individuals struggling with obesity and related health complications. Two common procedures are gastric band surgery and gastric sleeve surgery. While both aim to aid in weight loss, they have significant differences in how they function, their long-term effects, and their dietary implications. This article explores these differences, the benefits and risks of each procedure, recovery times, costs, and long-term dietary changes.

What is Gastric Band Surgery?
Gastric band surgery, also known as laparoscopic adjustable gastric banding (LAGB), is a minimally invasive procedure in which an adjustable silicone band is placed around the upper part of the stomach. This band creates a small pouch, reducing the stomach’s capacity and slowing down digestion, making the individual feel fuller with smaller portions of food.
How Does It Work?
- The band is adjustable and can be tightened or loosened by injecting or removing saline through a small port under the skin.
- The band isn’t designed to work via physical restriction alone, but rather it tricks the brain into thinking that more food is being eaten per mouthful swallowed, due to more of the stomach’s stretch receptors being activated earlier on during an eating episode.
- The procedure does not involve cutting or stapling the stomach.
- It requires regular follow-up visits to adjust the band as needed.
- Weight loss occurs gradually and is primarily dependent on lifestyle changes.

What is Gastric Sleeve Surgery?
Gastric sleeve surgery, or sleeve gastrectomy, involves removing approximately 75% of the stomach, leaving behind a tube-like portion. This significantly reduces stomach capacity and alters gut hormones responsible for hunger and metabolism.
How Does It Work?
- The stomach is permanently reduced in size, limiting food intake.
- Unlike the gastric band, no foreign objects are implanted.
- It leads to hormonal changes that suppress hunger and improve insulin sensitivity.
- Weight loss tends to be more rapid and substantial compared to gastric band surgery.

FAQs
What is the safest weight loss surgery? Both gastric band and gastric sleeve surgeries are considered safe when performed by experienced professionals. The gastric band has a lower initial surgical risk, while the gastric sleeve has a higher success rate for long-term weight loss.
How long does a gastric band last? A gastric band can last many years but may require adjustments or removal due to complications.
Can the stomach grow again after gastric sleeve? Yes, the stomach can stretch if portion sizes are consistently too large, but it will not return to its original size.
Do you still feel hungry with a gastric band? Hunger is usually reduced, but some people may still experience hunger between meals. Head and heart hunger (cravings and emotional eating) need to be managed with the help of a dietitian and psychologist.
Can you drink alcohol with a gastric band? Yes, but in moderation, which is the same as with the gastric sleeve – although we advise waiting 3-6 months after the operation before you consume alcohol. Carbonated drinks can cause discomfort.
Can you regain weight after gastric sleeve? Yes, if dietary guidelines are not followed, weight regain can occur. This article aims to provide a comprehensive understanding of gastric band and gastric sleeve surgeries, helping individuals make informed decisions about their weight loss journey.
