The gastric sleeve involves reducing the size of the stomach, typically by around 80% of its original size. The remaining 20% is sufficient to effectively promote weight loss without causing malnutrition in the patient.
In addition to the mechanical effect described, the gastric sleeve has a hormonal action. The part of the stomach that is removed or excised produces a hormone called Ghrelin, which is associated with hunger stimulation.
By removing this part of the stomach, blood levels of Ghrelin decrease, leading to reduced hunger and, consequently, weight loss.
