Introduction to Weight Loss Surgery

Weight loss surgery, also known as bariatric surgery, offers a powerful solution for individuals struggling with obesity and related health conditions.

Whether you’re considering surgery yourself or researching for a loved one, this guide aims to educate, empower, and prepare you for every step of the journey.

What is Weight Loss Surgery?

Weight loss surgery refers to a group of surgical procedures designed to help individuals lose weight by modifying the digestive system. These surgeries work by either restricting the amount of food the stomach can hold, reducing nutrient absorption, or both.

Goals of Bariatric Surgery:

  • Achieve significant, sustainable weight loss
  • Improve or resolve obesity-related health conditions
  • Enhance quality of life and life expectancy

Common Types of Weight Loss Surgery

1. Gastric Bypass (Roux-en-Y)

  • Creates a small pouch at the top of the stomach
  • Bypasses a portion of the small intestine
  • Benefits: Rapid weight loss, improvement in diabetes
  • Risks: Dumping syndrome, vitamin deficiencies

2. Sleeve Gastrectomy (Gastric Sleeve)

  • Removes about 80% of the stomach
  • Leaves a banana-shaped “sleeve”
  • Benefits: Simpler than bypass, fewer complications
  • Risks: Acid reflux, vitamin deficiencies

3. Adjustable Gastric Band (Lap-Band)

  • Inflatable band placed around upper stomach
  • Adjusted via port under skin
  • Benefits: Reversible and adjustable
  • Risks: Slower weight loss, risk of slippage

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

  • Combines sleeve gastrectomy and intestinal bypass
  • Benefits: Most effective for weight loss
  • Risks: Higher risk of malnutrition and complications
