Which group is at increased risk for small bowel obstruction?

The group comprised of older adults and infants is at increased risk for small bowel obstruction due to several anatomical and physiological factors. In older adults, the higher prevalence of conditions such as adhesions from previous surgeries, tumors, and hernias significantly contributes to the risk of obstruction. Age-related changes, like decreased gastrointestinal motility, can also play a role in this increased susceptibility.

Infants, on the other hand, are particularly prone to small bowel obstructions due to congenital anomalies like intestinal atresia or malrotation, as well as conditions such as intussusception, where a part of the intestine telescopes into itself. Their developing gastrointestinal systems and potential for rapid changes in hydration and electrolyte balance can further exacerbate the risk.

Both demographics show unique vulnerabilities that disrupt normal bowel function, emphasizing the importance of recognizing them as higher-risk groups for small bowel obstruction.
