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:
-
Creating a small stomach pouch
– The surgeon makes a long, narrow pouch from the stomach so you feel full with very little food. -
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:
-
Restriction:
The small pouch holds much less food, so you eat smaller meals and feel full quickly. -
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.
