Understanding Bariatric Surgery: Types and Procedures
Bariatric surgery encompasses several surgical procedures designed to help patients achieve significant and sustained weight loss. These procedures work through two main mechanisms: restriction (limiting food intake) and malabsorption (reducing nutrient absorption).
Primary Bariatric Surgery Types
Laparoscopic Sleeve Gastrectomy (LSG)
Most Popular Procedure: Removes 75-80% of the stomach, creating a small banana-shaped pouch. This restrictive procedure significantly reduces hunger hormones (ghrelin) and portion sizes.
- Expected weight loss: 60-70% of excess weight
- Surgery duration: 45-90 minutes
- Hospital stay: 2-3 days
Roux-en-Y Gastric Bypass (RYGB)
Gold Standard: Creates a small stomach pouch connected directly to the small intestine, bypassing most of the stomach and first portion of small intestine.
- Expected weight loss: 70-80% of excess weight
- Surgery duration: 90-120 minutes
- Excellent for diabetes resolution
Adjustable Gastric Band (AGB)
Adjustable Option: Places a silicone band around the upper stomach to create a small pouch, controlling food intake through adjustable restriction.
- Expected weight loss: 40-50% of excess weight
- Reversible procedure
- Requires regular follow-ups
Mini Gastric Bypass (OAGB)
Simplified Bypass: Single anastomosis procedure combining restriction and mild malabsorption with shorter operative time.
- Expected weight loss: 70-75% of excess weight
- Shorter surgery duration
- Lower complication rates

Post-Surgery Recovery Timeline
Recovery from bariatric surgery follows a structured timeline. Here's what to expect during your journey back to health:
| Time Period | Recovery Milestones | Dietary Progression | Activity Level |
|---|---|---|---|
| Day 0-1 | ICU monitoring, pain management, early mobilization | Clear liquids only | Bed rest → Chair sitting → Walking |
| Day 2-3 | Upper GI study, transition to ward, discharge planning | Full liquids (protein shakes) | Walking 3-4 times daily |
| Week 1-2 | Home recovery, staple removal, first follow-up | Pureed foods introduction | Light activities, no lifting >5kg |
| Week 3-4 | Return to light work, nutritional counseling | Soft solid foods | Gradually increase activity |
| Month 2-3 | Regular follow-up, weight loss progress assessment | Regular foods (small portions) | Exercise program initiation |
