Bariatric surgery is a transformative procedure designed to aid significant weight loss and improve health outcomes for individuals struggling with obesity. This guide explores the various types of bariatric surgery, their benefits, and potential risks to help you make an informed decision about this life-changing treatment.

Types of Bariatric Surgery

  1. Roux-en-Y Gastric Bypass (RYGB)
    • Procedure: Creates a small pouch from the stomach and connects it directly to the small intestine, bypassing a large portion of the stomach and the first part of the small intestine.
    • How It Works: Reduces the amount of food you can eat and decreases calorie absorption by altering the digestive tract.
    • Benefits: Significant weight loss, improved or resolved type 2 diabetes, and long-term weight maintenance.
    • Risks: Nutritional deficiencies, dumping syndrome, and higher risk of complications compared to other procedures.
  2. Sleeve Gastrectomy
    • Procedure: Removes about 75-80% of the stomach, leaving a tube-like structure (sleeve).
    • How It Works: Limits the amount of food you can eat and reduces hunger hormones.
    • Benefits: Significant weight loss, less complex than gastric bypass, lower risk of nutritional deficiencies.
    • Risks: Potential for long-term vitamin deficiencies, irreversible procedure.
  3. Adjustable Gastric Banding (AGB)
    • Procedure: Places an adjustable band around the upper part of the stomach to create a small pouch.
    • How It Works: Limits food intake and increases feelings of fullness by restricting the stomach size.
    • Benefits: Least invasive, adjustable, reversible, lower risk of nutritional deficiencies.
    • Risks: Slower weight loss, potential for band slippage or erosion, requires frequent follow-ups for adjustments.
  4. Biliopancreatic Diversion with Duodenal Switch (BPD/DS)
    • Procedure: Combines sleeve gastrectomy with bypassing a large portion of the small intestine.
    • How It Works: Reduces stomach size and significantly limits calorie and nutrient absorption.
    • Benefits: Most effective for weight loss and diabetes remission, significant metabolic improvements.
    • Risks: Higher risk of nutritional deficiencies and complications, requires lifelong follow-up and supplementation.
