Study Notes
Gastrointestinal (GI) Tract
- The GI tract is responsible for mechanical and chemical digestion, absorption of nutrients, and elimination of waste products.
Composition of the GI Tract
- The GI tract consists of the mouth, esophagus, stomach, small intestine, and large intestine.
Motility in the GI Tract
- The GI tract generates motility through the contraction and relaxation of smooth muscles, regulated by the enteric nervous system and hormonal secretions.
Importance of GI Tract Function
- The proper function and coordination of GI tract processes are vital for maintaining good health, as they enable the absorption of essential nutrients and eliminate waste products.
Disorders of Gut-Brain Interaction
- Functional gastrointestinal disorders (FGID) refer to a group of bowel disorders characterized by chronic abdominal complaints without a structural or biochemical cause.
- Main factors involved in FGID include altered motility, visceral sensitivity, and altered gut-brain interaction.
- The current definition for disorders of gut-brain interaction is based on the Rome IV criteria, which involves a multidisciplinary approach incorporating input from experts in gastroenterology, psychology, and neurology.
- The main characteristic of FGID is the absence of detectable structural or biochemical abnormalities despite chronic symptoms.
