What Is Weight Loss Surgery?
Weight loss surgery refers to various procedures designed to help individuals lose significant amounts of weight by altering the digestive system. These surgeries can reduce stomach size, limit food intake, or affect nutrient absorption.
Primary Goals:
- Achieve and maintain significant weight loss
- Improve or resolve obesity-related health conditions
- Enhance quality of life
Common Types of Weight Loss Surgery
1. Gastric Bypass (Roux-en-Y)
- Creates a small stomach pouch
- Bypasses part of the small intestine
- Benefits: Rapid and substantial weight loss, improvement in diabetes
- Risks: Nutritional deficiencies, dumping syndrome
2. Sleeve Gastrectomy
- Removes ~80% of the stomach
- Smaller stomach = less food intake
- Benefits: Simpler procedure, fewer complications
- Risks: Irreversible, potential for acid reflux
3. Adjustable Gastric Band (Lap-Band)
- Inflatable band placed around the stomach
- Adjustable via port
- Benefits: Reversible, adjustable
- Risks: Slower weight loss, band slippage
4. Biliopancreatic Diversion with Duodenal Switch (BPD/DS)
- Combines sleeve gastrectomy with intestinal bypass
- Benefits: Most effective for weight loss and diabetes control
- Risks: Highest risk of nutrient deficiency
