How Does Sleeve Gastrectomy Work?
Sleeve gastrectomy (sometimes referred to as gastric sleeve or vertical sleeve gastrectomy) works in many ways to achieve sustained weight loss and resolution or improvement of the obesity related health conditions.
1. Restriction
The small volume of the stomach tube (average around 150 mL) limits the amount of food that can be consumed at any given time. Unlike a gastric band where there is one area of fixed narrowing, in sleeve gastrectomy the whole stomach tube is narrow but pliable allowing patients to eat normal meals but in small portions and feeling full afterwards. The sleeve allows patients to control food portions and improve long term eating habits. It is particularly effective in patients who tend to eat large meals.
