Which combination best describes the common causes of constipation in older adults and an appropriate management approach?

• A. Dehydration is the main cause; management is to increase laxatives only.
• B. Limited mobility and opioid use; management includes hydration, fiber, activity, and stool softeners if needed.
• C. Regular exercise cures constipation; no dietary changes are needed.
• D. Avoiding fluids prevents constipation.

Answer: (B)

Constipation in older adults is often multifactorial, with reduced mobility and the use of opioids being two of the most common and impactful contributors. Limited physical activity slows intestinal movement, while opioids directly slow gut motility and decrease stool frequency and ease of passage. Because these factors frequently occur together in the elderly, addressing both the physical and pharmacologic influences gives the most effective, practical management. A solid approach starts with nonpharmacologic steps: ensure adequate hydration, include dietary fiber as tolerated, and encourage activity or movement that the person can safely perform. Establishing a regular toileting routine also helps train bowel habits. If stools are still hard or infrequent, adding a stool softener can make passage easier. Should these measures be insufficient, a healthcare provider may consider other laxatives or osmotic agents, but only with careful monitoring for dehydration, electrolyte changes, and interactions with other medications. Importantly, addressing the underlying contributors—mobility and opioid effect—while supporting softer, easier-to-pass stools provides a balanced, sustainable plan. The other options don’t fit as well because relying on laxatives alone misses the need to address reduced mobility and opioid-induced slowing, claiming exercise alone cures constipation ignores the essential roles of hydration and fiber, and avoiding fluids would almost certainly worsen constipation.
