Obesity Surgery


Obesity surgery, also known as bariatric surgery, is a collection of procedures designed to help individuals with severe obesity lose weight when traditional methods like diet and exercise have not been effective.

About Obesity Surgery

Obesity surgery works by either limiting the amount of food the stomach can hold, causing malabsorption of nutrients, or a combination of both gastric restriction and malabsorption. These procedures not only aid in significant weight loss but also improve many obesity-related conditions, such as type 2 diabetes, high blood pressure, and sleep apnea.

Types of Obesity Surgery

Gastric Bypass Surgery: It involves creating a small pouch from the stomach and connecting it directly to the small intestine, bypassing a large part of the stomach and duodenum.

Sleeve Gastrectomy: This involves removing about 80% of the stomach, leaving a tube-like portion of the stomach in place, and eliminating the portion that produces the hunger-stimulating hormone ghrelin.

Adjustable Gastric Band: This procedure involves placing a band around the upper part of the stomach to create a small pouch to hold food, limiting the amount of food that can be consumed at a time.

Biliopancreatic Diversion with Duodenal Switch (BPD/DS): A more complex procedure that removes a large part of the stomach and bypasses a significant portion of the small intestine.


  • Effective Weight Loss: Most patients experience significant and long-term weight loss, helping improve quality of life.
  • Improved Health Conditions: Conditions such as diabetes, high blood pressure, and cholesterol levels often improve or resolve completely.
  • Increased Energy and Mobility: Weight loss can lead to increased energy levels and greater mobility.
  • Enhanced Psychological Well-being: Many patients report improvements in mood, self-esteem, and quality of life.

Candidates for the surgery typically include those with a BMI of 40 or higher or a BMI of 35 or higher with obesity-related health conditions. The decision to undergo the surgery should be made in consultation with a healthcare provider, considering the potential benefits and risks.

Is obesity surgery reversible?

Some types of obesity surgery, such as gastric banding, are reversible, while others, like gastric bypass and sleeve gastrectomy, are generally considered permanent. Reversibility depends on the specific procedure and individual circumstances.
