How does the Gastric Bypass Help you to Lose Weight?

The gastric bypass procedure helps you to lose weight in two ways:

  • By limiting the amount of food that can be eaten at any one time to less than a 10% of what you can eat now.
  • By decreasing the amount of calories you absorb from your food as a result of bypassing the duodenum (upper part of the small intestine).

It is important to remember that surgery is a TOOL for weight loss. It is vital that eating behaviours are modified to get the best result from the procedure. It is important to eat a variety of healthy foods, to limit your intake of calorie dense foods and liquids and to slow your speed of eating to improve food tolerance. If eating behaviours are not adapted after surgery, weight loss will be limited or weight regain can be possible in the future. More detailed information about correct eating behaviours will be covered during your visit with the dietitian.
