Roux-en-Y“ Gastric Bypass” Surgery
With gastric bypass surgery, a small pouch is created by stapling close the top part of the stomach, which separates it from the lower part. Then, the small intestine is brought up to join with this pouch. The small intestine pathway is then reconstructed lower in the GI tract to restore intestinal continuity.
How does it work?
• The pouch is small and gets full with food easily, which makes you feel full very fast.
• It also limits the number of calories and nutrients that the small intestine can take in.
• It changes the gut hormones to make you feel less hungry and fuller for a longer time.
Average Surgery Time: 1.5 hours Hospital Stay: 1-3 nights
Risks:
● Vitamin deficiencies – most common long-term risk
● Dumping syndrome: when your stomach empties what is inside very fast into your small intestine
● Stomach and parts of the intestine cannot be viewed if there are problems after surgery like ulcers or bleeding
● Leaks from staple line
● Ulcers, a breakdown of the skin lining your stomach and intestine
