The gastric bypass operation is truly a bypass of the stomach. During the surgery, the stomach is divided into two sections: a small upper pouch and a larger lower pouch. The small intestine is then rearranged to connect the upper pouch directly to a lower section of the small intestine, bypassing a portion of the stomach and the first part of the small intestine (duodenum). This creates a “Y” shape, which gives the surgery its name.
Gastric bypass surgery works through two main mechanisms:
Gastric bypass surgery can result in significant weight loss. The combination of restriction and malabsorption contributes to weight loss by reducing the amount of food intake and the body’s ability to absorb calories. Patients can expect to lose 50-80% of their excess weight within the first year post-surgery. The exact amount can vary based on individual compliance with dietary and lifestyle changes.
Many patients achieve substantial and sustained weight loss after the procedure. Other important improvements include:
Other potential benefits of a gastric bypass include eliminating gastro-oesophageal reflux disease (GORD), or “heartburn”, which some patients have due to an underlying hiatal hernia defect or from prior gastric sleeve surgery.
To be eligible for gastric bypass surgery, patients are put through a thorough pre-surgery evaluation, including medical and psychological assessments to determine their suitability for surgery. A successful outcome require significant lifestyle changes, including adopting a healthy diet, regular exercise, and long-term follow-up with medical professionals.
Most patients who undergo gastric bypass surgery meet the following criteria:
Like any surgical procedure, there are potential risks and complications, including infection, bleeding, blood clots, and adverse reactions to anaesthesia.
