Laparoscopic Gastric Bypass

In this procedure the stomach and first part of the small intestine are bypassed — this restricts food intake and stimulates hormones that suppress hunger and improve Type II diabetes.


  • The small stomach pouch and hormonal effect produce a strong sensation of fullness with very small meals
  • Excellent weight loss, sustained long-term
  • Dumping syndrome makes it harder to cheat by eating sweets


  • Leaks from staple lines and joins
  • Ulcers, particularly in smokers
  • There is a small risk of intestinal blockage
  • Life-long vitamin supplements are required
