GASTRIC BYPASS SURGERY
A proven approach to weight loss that reduces stomach size and helps regulate appetite and blood sugar.
WHAT IS GASTRIC BYPASS SURGERY?
With a gastric bypass, also known as Roux-en-Y gastric bypass, your surgeon uses a small portion of your stomach to create a new stomach pouch that is about the size of an egg, which is then connected directly to your small intestine.
The remaining large portion of your stomach and the duodenum is 'bypassed', however, the excluded stomach tissue is not removed, ensuring that essential digestive juices, enzymes and hormones continue to be produced and absorbed.
PROS AND CONS OF ROUX-EN-Y GASTRIC BYPASS
Disadvantages can include: Requires lifelong compliance with specific lifestyle changes (diet and exercise), patients need to be monitored for vitamin deficiencies, overeating following gastric bypass surgery can lead to nausea, diarrhea, and discomfort, and the procedure is permanent
Patients can continue to enjoy most foods by limiting portion sizes
The resulting metabolic changes can reduce food cravings
When done using robot-assisted techniques, scarring, complication rates, and post-surgical pain are minimal
HOW DOES GASTRIC BYPASS WORK?
Gastric bypass works by restricting the amount of food you can eat, and altering the way in which fat and calories are absorbed by your body.
The small, egg-sized stomach pouch fills up quickly when you eat, which helps you feel satisfied on a fraction of the food that you consumed prior to the procedure. As a result, you take in fewer calories, leading to a caloric deficit and subsequent weight loss.
Because a portion of the small intestine is bypassed during the procedure, your body will absorb fewer nutrients from the food you eat - this also helps to promote weight loss and long-term maintenance of a healthy body mass index (BMI).
