Study Notes
Pathophysiology of the Digestive System
- The gastrointestinal system breaks down nutrients and absorbs them into the body through mechanical and chemical processes.
- The system functions under autonomic nervous system control. Activation of the sympathetic nervous system decreases digestive functions, while activation of the parasympathetic nervous system increases them.
- Digestive insufficiency is a disruption in the digestion/absorption of nutrients. It can be total or selective.
- Digestive system disorders can be categorized by anatomical location, clinical course, etiology, or by the functions affected.
- Various etiological factors affect digestive system diseases. These include dietary factors (e.g., quality, temperature of food), physical factors (radiation), chemical factors (toxins), biological factors (infections), mental/emotional factors, social factors (addiction), and pre-existing conditions (tumors, endocrine problems).
- Disorders of taste sensitivity and appetite can manifest as ageusia, hypogeusia, hypergeusia, parageusia, or dysgeusia.
Digestive Disorders in the Oral Cavity
- Chewing disorders occur when the chewing apparatus is damaged or malfunctioning(e.g. teeth, jaw muscles).
- Dysfunction of the salivary glands can disrupt food processing, causing difficulties in the act of swallowing and digestion.
- Reduced salivary production can cause dry mouth and difficulty chewing.
Disorders of Taste and Appetite
- Ghrelin, gastrin, oxytocin, acetylcholine, increase appetite and leptin decreases appetite.
- Various conditions affect appetite, including anorexia and hyperorexia.
- Damage to the taste centers and nerves can also impact taste sensitivity.
Digestive Disorders in the Stomach and Duodenum
- Peptic ulcers are chronic conditions that affect the stomach and duodenum. Major causes include infections by Helicobacter pylori and use of nonsteroidal anti-inflammatory drugs (NSAIDs).
- Disorders of the stomach’s motility, secretions, and barrier function contribute to digestive issues, such as ulcers.
- Hypersecretion, hyposecretion, and other gastric disorders affect the quantity and quality of gastric juice, and its function in digestion.
Disorders of the Small Intestine
- Enzymopathies can severely impact nutrient breakdown in the small intestine, causing malabsorption.
- Issues with the small intestine's secretory function (hyposecretion) can also lead to malabsorption.
- These issues can have various causes, including damage to the intestinal surface/mucosa, insufficient enzyme production, and a malfunctioning of the digestive barrier.
Disorders of the Large Intestine
- Inflammatory disorders also can affect the large intestine (e.g., colitis).
- Pathologies such as constipation and diarrhea can result from various factors affecting intestinal motility and secretion.
- Problems with bowel movements are often caused by abnormal intestinal motility/muscle contractions, blockage, or hormonal issues.
