What percentage of the stomach is removed during a sleeve gastrectomy?

In a sleeve gastrectomy, approximately 75% of the stomach is removed. This surgical procedure involves creating a tube-like structure, or "sleeve," from the remaining portion of the stomach. The significant reduction in stomach size limits the amount of food that can be consumed, which aids in weight loss. By removing such a large portion of the stomach, the surgery also reduces the production of ghrelin, the hormone responsible for stimulating appetite. This dual effect of physical restriction and hormonal changes contributes to effective weight management post-surgery. Thus, the percentage removed during this type of gastric surgery is indeed around 75%.
