    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.
