Abstract

All bariatric procedures induce anatomical and physiological changes at different levels in the digestive system, according to their technical design. There are procedures where the modifications are milder and even reversible, such as Laparoscopic Adjustable Gastric Band. There are others where profound and irreversible alterations are expected in the anatomical configuration and in the physiological functioning because of extensive small bowel diversion along with gastric resection. Having a thorough knowledge of these changes is important for all professionals involved in the surgical treatment of patients suffering from morbid obesity. It helps to understand the presumed therapeutic outcomes, as well as to promptly identify and manage the possible adverse events that may result from these procedures. In this chapter, the main anatomical and physiological changes in the digestive system resulting from the most commonly performed bariatric procedures are addressed.

In understanding the basics of digestion, you’ll discover who’s in charge. Here’s a hint. It’s not you.
