Gastric Bypass

A gastric bypass is a weight loss surgery procedure that uses both restrictive and malabsorptive elements. The result is you simply cannot eat as much and thus you absorb fewer calories.

Advantages of gastric bypass surgery

• Rapid initial weight loss
• Slightly higher total average weight loss reported than with adjustable gastric band.

Disadvantages of gastric bypass surgery

• Complex procedure requiring cutting and stapling of stomach and bowel
• More operative complications than with adjustable gastric band
• Medical complications due to nutritional deficiencies are expected, meaning dietary supplements are required for the remainder of the patient’s life
• ‘Dumping syndrome’ can occur - resulting in nausea, sickness and diarrhoea
• Non adjustable.
