Types of Weight Loss Procedures

Quick Comparison

Gastric Bypass Surgery

  • Procedure: A small stomach pouch is created that bypasses the rest of the stomach and attaches directly to the small intestine.
  • Method: Limits the amount of food that can be eaten at one time, which helps you to feel fuller sooner, and reduces the amount of calories your body can absorb from food.
  • Weight loss: Rapid. Lose 60-80% of excess body weight within 12 to 18 months.
  • Surgery time: 1.5 hours
  • Hospital stay: Typically 1 day
  • Recovery time: About 2–4 weeks
