Final answer:
Constipation in the elderly is caused by factors such as medication side effects, reduced physical activity, decreased fluid intake, and aging-related changes in the colon. Additional factors like diverticular disease and decreased function of digestive organs also contribute. Managing this condition requires a holistic approach, including medical, lifestyle, and dietary modifications.
Step-by-step explanation:
C. Decreased fluid intake Constipation in the elderly can be attributed to a variety of factors. Some of these factors include medication side effects, reduced physical activity, decreased fluid intake, and aging-related changes in the gastrointestinal system. Medications can often contribute to constipation as a side effect. Additionally, the elderly may engage in less physical activity, which can reduce the motility of the gut and lead to constipation. A decrease in fluid intake can also exacerbate constipation, as fluids are necessary for stool formation and transit. Finally, aging can bring about physiological changes in the colon, such as reduced muscle strength and nerve function, that can affect bowel movements.
Pathologies that affect the digestive organs, including diverticular disease and decreased digestive organ function, can occur more frequently with aging. Factors such as diet and overall health play a significant role in bowel movement regularity as well. Therefore, it's essential to consider a comprehensive approach to managing constipation in elderly individuals, which may include addressing underlying medical conditions, adjusting medications, increasing physical activity, ensuring adequate hydration, and optimizing dietary intake.
