Mini Gastric Bypass (MGB) / One Anastomosis Gastric Bypass (OAGB)

A Safe and Effective Weight-Loss Surgery

A Powerful and Effective Weight-Loss Surgery
Mini Gastric Bypass, also known as OAGB, is a highly effective bariatric (weight-loss) surgery that helps people lose significant weight and improve obesity-related health problems. It is a safe, minimally invasive procedure commonly chosen when long-term weight control has been difficult.
What Happens in Mini Gastric Bypass?
The surgery is done laparoscopically through small keyhole cuts.
The procedure has two key steps:
  1. Creating a small stomach pouch
    – The surgeon makes a long, narrow pouch from the stomach so you feel full with very little food.
  2. Bypassing a part of the small intestine
    – A portion of the small intestine is connected directly to the new pouch.
    – This reduces calorie and fat absorption.
How Does Mini Gastric Bypass Help in Weight Loss?
MGB/OAGB helps you lose weight in two powerful ways:
  1. Restriction:
    The small pouch holds much less food, so you eat smaller meals and feel full quickly.
  2. Malabsorption:
    A part of the intestine is bypassed, so the body absorbs fewer calories and fats.
As a result, patients experience faster and long-lasting weight loss.
