Gastrointestinal Hormones: Introduction and Index


Digesting, absorbing and assimilating a meal requires precise coordination of a huge number of physiologic processes. Control over gastrointestinal function is, as one would expect, provided by nervous and endocrine systems.

The hormones most important in controlling digestive function are synthesized within the gastrointestinal tract by cells scattered in the epithelium of the stomach and small intestine. These endocrine cells and the hormones they secrete are referred to as the enteric endocrine system. Interestingly, most if not all "GI hormones" are also synthesized in the brain.

The following discussions assume some familiarity with the anatomy and physiology of the digestive system.

Core information on gastrointestinal hormones is presented in the following topics:
