When it comes to long-term weight loss solutions, two of the most effective bariatric procedures are gastric bypass and sleeve gastrectomy. Both surgeries can help patients lose significant weight, manage obesity-related conditions, and improve overall health—but they work in different ways.
In this guide, we’ll compare gastric bypass vs. sleeve gastrectomy, explore their benefits, and help you understand which option might be best for your weight-loss journey.

What Is Gastric Bypass Surgery?
Gastric bypass, also known as Roux-en-Y gastric bypass, is one of the oldest and most well-studied bariatric procedures.
How It Works:
- A small stomach pouch is created by dividing the upper part of the stomach.
- This pouch is then connected to the small intestine, bypassing a large portion of the stomach and digestive tract.
Benefits:
- Rapid and significant weight loss
- Excellent outcomes for type 2 diabetes and acid reflux
- Long-term weight maintenance with proper follow-up
What Is Sleeve Gastrectomy?
Sleeve gastrectomy, commonly referred to as gastric sleeve surgery, is a minimally invasive procedure that removes about 75–80% of the stomach, creating a smaller, sleeve-shaped stomach.
How It Works:
- Limits food intake by reducing stomach size
- Lowers hunger hormone levels (ghrelin), which naturally suppresses appetite
Benefits:
- Simpler surgery than gastric bypass
- No rerouting of intestines
- Effective for weight loss and obesity-related conditions
- Lower risk of certain complications
