Gastric bypass surgery

About the Procedure
Gastric Bypass Surgery - Complete and Simple Guide
What is gastric bypass surgery?
Imagine your digestive system is like a long road, and gastric bypass surgery is like creating a "shortcut" that bypasses most of the stomach and part of the intestines!
How it works?
- Shrink the stomach - From football size to walnut size
- Reroute food - Bypasses most of stomach and first intestines
- Less absorption - Body absorbs fewer calories
Result: Eat very little + absorb less = major weight loss!
Simple analogy: Like redirecting a big river into a small stream - same water but less flow
Who needs gastric bypass surgery?
Basic cases:
✅ BMI over 40 - Severe obesity
✅ BMI 35-40 with diseases - Diabetes, blood pressure, heart
✅ BMI 30+ with serious problems - Exceptional cases
✅ Failed other methods - Diet, exercise, medications, simpler surgeries
Psychological and physical requirements:
- Ready for radical change - Completely new lifestyle
- Commitment to supplements - For life
- Regular follow-up - Routine checkups
- Mental health - Prepared for challenges
When is it the first choice?
- Very severe obesity - Weight 150+ kg
