Study Notes
Gastrointestinal Tract
- The alimentary tract/canal extends from mouth to anus
- Organs involved: stomach, small intestine, and large intestine
- Stomach: Located in the upper abdomen. Stores food, secretes digestive juices, and churns food to propel chyme to small intestine
- Pyloric sphincter: A muscular ring regulating chyme release from stomach to small intestine
- Small intestine: Contains duodenum, jejunum, and ileum. Releases enzymes digesting proteins and carbohydrates. Receives digestive secretions from liver and pancreas. Facilitates food digestion and nutrient absorption
- Large intestine: Absorbs water, forms feces, and expels feces. Ileocecal valve prevents premature large intestinal entry and backward movement of contents to small intestine
Bowel Elimination
- The lower part of the GI tract extends from the ileocecal valve to the anus
- Includes ascending colon (right side), transverse colon, descending colon (left side), sigmoid colon, rectum, and anus
Defecation
- Feces, or stool, is waste expelled from the colon
- Defecation is the process of bowel elimination, propelled by peristalsis
- Controlled by the medulla and spinal cord.
Bristol Stool Chart
- A tool to describe stool consistency
- Types range from separate hard lumps (Type 1) to watery (Type 7)
Diagnostic Studies
- Stool sample collection for lab analysis; avoid urine contamination.
- Possible need for bowel preparation in some cases.
- Barium or IV contrast may be used.
Considerations
- Surgical procedures/anesthesia can disrupt bowel motility.
- Pain management can lead to constipation.
- Thorough assessment necessary for bowel pattern/consistency changes and related pain.
Other Agents for Bowel Function
- Suppositories/oils (melt at body temperature) for constipation
- Oral solutions (e.g., colyte) for bowel cleansing, used before surgery
Bowel Diversion: Ostomy
- Surgical creation of an opening from the interior of an organ to the exterior.
- Types include ileostomy (small intestine) and colostomy (large intestine)
Promoting Normal Bowel Function
- Adequate fiber and fluid intake are key.
- Regular exercise improves GI motility.
- Manage lifestyle factors like stress, cleanliness, and occupation.
Treatment for Constipation
- Bulk-forming agents
- Osmotic agents (polyethylene glycol)
- Stimulant agents
- Softeners
- Lubricants
