What are the 3 types of weight loss surgery

For individuals struggling with obesity, weight loss surgery in Islamabad can be a life-changing solution. Also known as bariatric surgery, these procedures aim to assist people in achieving significant and sustainable weight loss.

In this blog, we will delve into the three primary types of weight loss surgery, providing insights into their procedures, benefits, and considerations. By understanding these options, individuals can make informed decisions in consultation with their healthcare providers.

Gastric Bypass Surgery:

It is one of the most common and effective weight loss procedures and involves reducing the stomach’s size and rerouting the digestive system. The surgeon creates a small pouch at the top of the stomach, separating it from the rest of the organ. This pouch is then directly connected to the small intestine, bypassing a portion of the stomach and the upper part of the small intestine.


  • It promotes significant and sustainable weight loss by limiting the amount of food the stomach can hold and altering the absorption of nutrients.
  • The rerouting of the digestive system affects the release of hormones, including ghrelin and glucagon-like peptide-1, which regulate appetite and metabolism.
  • It can lead to the resolution or improvement of obesity-related health conditions such as type 2 diabetes, high blood pressure, and sleep apnea.


  • Surgical risks: As with any surgical procedure, gastric bypass surgery carries certain risks, including infection, bleeding, and blood clots.
  • Nutritional considerations: After surgery, individuals may require lifelong vitamin and mineral supplementation to prevent deficiencies due to reduced absorption.
  • Dietary changes: Patients need to adopt significant dietary modifications, including smaller portion sizes, increased protein intake, and avoidance of high-sugar and high-fat foods.

Sleeve Gastrectomy:

Sleeve gastrectomy, also known as gastric sleeve surgery, involves removing a large portion of the stomach to create a smaller, banana-shaped sleeve. This procedure restricts the stomach’s capacity, making individuals feel fuller sooner and reducing the production of hunger-inducing hormones.


  • This results in substantial weight loss by restricting the amount of food the stomach can hold and reducing hunger.
  • Compared to more complex procedures like gastric bypass, sleeve gastrectomy carries a lower risk of complications and malabsorption issues.
  • The surgery often leads to the resolution or improvement of conditions such as type 2 diabetes, high blood pressure, and sleep apnea.


  • Irreversible procedure: Unlike gastric banding, sleeve gastrectomy is irreversible, as a large portion of the stomach is permanently removed.
  • Long-term follow-up: Patients should adhere to regular follow-up appointments to monitor their progress, address any potential complications, and receive guidance on maintaining weight loss.

Adjustable Gastric Banding:

Adjustable gastric banding, often referred to as lap band surgery, involves placing an inflatable silicone band around the upper part of the stomach, creating a small pouch. The band is connected to a port placed under the skin, allowing for adjustments to control the degree of restriction.


  • Adjustable gastric banding is reversible, as the band can be removed if necessary.
  • Compared to other weight loss surgeries, adjustable gastric banding generally carries a lower risk of complications.
  • Weight loss with this procedure tends to be more gradual, allowing for adjustment and adaptation to new eating habits.


  • Slower weight loss: While adjustable gastric banding can result in significant weight loss, the pace is generally slower compared to other procedures.
  • Band-related complications: The band may cause complications such as slippage, erosion, or band intolerance, requiring additional surgical interventions.
  • Lifelong follow-up: Regular follow-up visits are crucial to monitor the band’s position, adjust the band if necessary, and ensure optimal weight loss progress.
