Complications Of Aging
Choose a question to answer. My question to answer is: “List and describe the physiological changes related to the digestive system of the elderly.” In addition to answering the question posed, make sure to provide an example of a patient in which you might check these labs, perform a test, give an injection, etc., and explain how the results or your new knowledge could affect your plan of care. You may use the textbook as one reference (see attached pictures of chapter #24) and the learning materials posted within the course. To deepen your understanding, you are also required to locate a scholarly article related to your aging discussion question.
Your answer should be based on pathophysiological principles specifically related to aging. Focus on the pathophysiology behind the changes rather than only listing diseases. For example, explain why an older patient might have a poor appetite and how this relates to gastric juice concentration, or why polyps develop in the colon with aging, such as due to slowed peristalsis.
Ensure your discussion emphasizes the internal changes within the digestive system associated with aging, such as decreased salivary secretion, reduced elasticity of the stomach, or changes in intestinal motility. Apply this knowledge to advanced practice nursing by considering how these physiological changes influence assessment, diagnostics, and interventions.

The process of aging induces significant physiological changes in the digestive system, affecting the structure and function of its components. These alterations can predispose elderly individuals to various gastrointestinal conditions, impacting nutrition, absorption, and overall health outcomes.
One of the primary changes involves the salivary glands, which typically produce less saliva with age. This reduction can lead to xerostomia, or dry mouth, impairing the initial phase of digestion by making swallowing difficult and reducing the enzymatic breakdown of carbohydrates. The decreased secretion also impacts taste and appetite, potentially leading to malnutrition. From an advanced nursing perspective, assessing saliva production and hydration status becomes essential, especially when planning nutritional interventions for the elderly (Gould, 2014).
The stomach also undergoes structural and functional changes. The gastric mucosa becomes thinner, and the number of acid-producing parietal cells declines, leading to hypochlorhydria or even achlorhydria. This reduction in gastric acid can impair digestion and absorption of nutrients such as vitamin B12, calcium, and iron. Consequently, elderly patients are at increased risk of deficiencies that may impact bone health and neurological function. For example, a patient presenting with anemia might have their gastric pH assessed via endoscopy and labs for vitamin B12 levels. If low acid production is confirmed, treatment may include supplementation or modified diets to mitigate deficiency risks (VanMeter & Hubert, 2014).
Furthermore, the intestinal system exhibits decreased motility due to slowed peristalsis, decreased neural responsiveness, and changes in smooth muscle structure. This can result in common complaints such as constipation, which significantly affects quality of life. The colon may develop polyps or diverticula, partly due to prolonged transit time and repeated mucosal injury or inflammation. These structural changes elevate the risk of colorectal cancer and require surveillance strategies, including colonoscopy screenings, especially given the increased prevalence of polyps in older adults.
The liver and gallbladder also experience functional declines. Liver mass decreases slightly, and hepatic blood flow reduces over time, which can affect drug metabolism and the processing of nutrients. Gallstone formation is more common due to altered bile composition and motility of the gallbladder, which can be monitored via abdominal ultrasound when patients present with biliary symptoms. Recognizing these changes enables nursing practitioners to adjust medication dosages appropriately and educate patients on dietary habits that favor gallbladder health.
In terms of clinical application, routine laboratory tests such as serum vitamin B12, iron levels, liver function tests, and screening for occult blood in stool can be instrumental in early detection of age-related gastric and intestinal changes. For instance, if an elderly patient reports decreased appetite or weight loss, evaluating for gastric atrophic changes or malabsorption syndromes can guide appropriate nutritional and pharmacological interventions. Additionally, patient education on the importance of regular screening endoscopies and colonoscopies could aid in early detection of polyps or cancers.
Incorporating these pathophysiological insights into nursing practice underscores the importance of comprehensive assessment strategies tailored to the aging population. It also emphasizes the need for preventive measures, such as vaccination against Helicobacter pylori, modification of diet, and early intervention for metabolic and structural alterations within the digestive system. Overall, understanding the internal changes due to aging informs more effective, individualized care plans aimed at maintaining gastrointestinal health and preventing complications in elderly patients.
