The clinical symptoms of functional
constipation in the
elderly are more unique which represents as over concern about their
bowel movement,excessive straining and worse
feelings to the
constipation.The intestinal physiological function declining with age,reductions of enteric
neurons and
interstitial cells of Cajal,neuronal degeneration and injured contractibility of intestinal smooth
cells are enrolled in the pathogenesis of functional
constipation.More
attention should be paid to
drug interactions and
adverse effects in clinical practice due to more underlying
disease and concomitant medication in the
elderly.
