Vertical Sleeve Gastrectomy, also called vertical gastric sleeve or even just ‘the sleeve’, is rapidly becoming the most common bariatric procedure performed because it has fewer complications and does not interrupt the digestive process as significantly as a traditional gastric bypass. During the Vertical Sleeve Gastrectomy, between 80% and 85% of the stomach is surgically removed and the remaining stomach stapled closed. What remains is a banana-shaped sleeve that is only able to hold 70 – 100 ml of volume (2 – 3 ounces).
The benefits of Vertical Sleeve Gastrectomy come from the removal of part of the stomach which automatically limits the amount of food you can consume, as well as from the effect on gut hormones that result from removing part of the stomach. These changes to the gut hormones impact suppress hunger, reduce appetite and improve satiety. Studies have shown a significant improvement in blood sugar levels with the Vertical Sleeve Gastrectomy, also as a result of the removal of stomach tissue.
This procedure is not reversible and, due to the small size of the stomach, it is necessary for you to make important nutritional changes. With reduced calorie consumption, you may also experience vitamin deficiency, which means you will need to follow your surgeon’s instructions for dietary supplements for the rest of your life. You can expect to lose up to 60 percent of your excess body weight in the first year and a half after surgery.
