What is Bariatric Surgery?

Bariatric surgery refers to medical procedures that alter the digestive system to promote weight loss. Doctors usually recommend it when the BMI scale indicates obesity (BMI ≥ 40 or ≥ 35 with health concerns) and when lifestyle changes like diet and exercise haven’t worked.

According to the World Health Organization (WHO), obesity is one of the leading preventable diseases worldwide, and bariatric surgery is a proven method of reducing associated risks such as diabetes, hypertension, and heart disease. WHO Obesity Facts.

Why Bariatric Surgery Matters in Obesity Management

Obesity isn’t just about body weight. It’s about how excess weight affects every system in your body—your heart, your lungs, your hormones, and even your confidence. Bariatric surgery matters because:

• It helps people lose 50–80% of excess weight sustainably.

• It can reverse type 2 diabetes in many patients.

• It reduces blood pressure and cholesterol.

• It helps improve fertility and mobility.

• It extends life expectancy by up to 7 years (based on long-term studies).

Types of Bariatric Surgery

1. Gastric Bypass (Roux-en-Y)

• Creates a small stomach pouch and bypasses part of the small intestine.

• Average excess weight loss: 60–80%.

• Strong effect on diabetes remission.

2. Gastric Sleeve (Sleeve Gastrectomy)

• 80% of the stomach is removed, reducing capacity and hunger hormones.

• Effective and simpler than bypass.

• Average excess weight loss: 50–70%.

3. Adjustable Gastric Band (Lap-Band)

• Silicone band placed around the upper stomach.

• Adjustable via saline injections.

• Reversible but less common today.

4. Biliopancreatic Diversion with Duodenal Switch (BPD/DS)

• Most complex but also most powerful for weight loss.

• Requires strict long-term supplement and nutrition care.

  5.Duodenal Switch

  Combines sleeve with intestinal bypass, offering extensive malabsorption for high BMI patients. [Surgical Clinics]

  6.Endoscopic Sleeve Gastroplasty and Robotic Surgery (2025 Trends)

  Minimally invasive, no external incisions, faster recovery, and precise surgery with robotic assistance. [Dr. Ruben Luna][Bumrungrad Endoscopic]

How Bariatric Surgery Works: Mechanisms of Weight Loss

Bariatric surgery causes weight loss through stomach restriction, malabsorption, and hormonal changes that reduce appetite and improve metabolism (like insulin sensitivity). The gut hormone adjustments often resolve type 2 diabetes soon after surgery. [Obesity Canada CPG]
