The gastric bypass is both a restriction and malabsorption procedure. By making a small stomach pouch, the amount of food that can be eaten at any one time is restricted.
Secondly, bypassing a portion of the gastrointestinal tract makes the body less efficient at absorbing nutrients (calories).
The result is a daily intake of calories less than the amount the body requires, leading to effective weight loss.
Most patients do not feel hungry after this procedure. Success is achieved with a patient's simultaneous change in eating patterns.
Recovery time for patients who have a gastric bypass procedure is usually two weeks.
