Is a surgical weight-loss procedure in which the stomach is reduced to about 20% of its original size, by surgical removal (resection) of an 80% of the stomach, being sufficient to perform normal digestion functions and store food.
The stomach is surgically stapled to form a sleeve or tube with a banana shape and the rest of the stomach is removed, the stomach portion that is removed is where the ghrelin hormone is produced; substance which stimulates the appetite.
This surgery is restrictive, which means that you are going to ingest a smaller amount of food because your stomach is smaller, also your appetite is smaller since production of the hormone in charge of generating hunger is reduced.
