What is the gastrointestinal system?
Essentially, it is a tube that extends from the mouth to the anus. It has a similar structure throughout. It is made up of a hollow portion of the tube known as the lumen, a muscular layer in the middle, and a layer of epithelial cells. These layers are responsible for maintaining the mucosal integrity of the tract.
Parts of the gastrointestinal system include the mouth, esophagus, stomach, small intestine, and large intestine.
The main functions of the gastrointestinal tract are the transportation, digestion, and absorption of food.
Bariatric surgery changes the Gastrointestinal System by creating a smaller stomach pouch. The surgeon then attaches a section of the small intestine directly to the pouch. This allows food to bypass a part of the small intestine, which normally absorbs calories and nutrients. Having a smaller stomach helps you feel fuller sooner and eat less food.
