2. Essentially normal digestion and absorption occur in elderly individuals.
However, many changes in the digestive system parallel age-related

STATION 21: Effect of aging on the digestive system
Decrease in mucus layer,
connective tissue, muscles
and secretions resulting in
increased susceptibility to
damage by abrasion, acids,
or enzymes. Peristaltic
contractions become
weaker, slowing the rate of
intestinal movement and
promoting constipation.
Increased
susceptibility to
infections and toxic
agents, resulting in
ulcerations and
cancers,
specifically colon
and stomach
cancer.
Gradual loss of teeth
due to cavities and/or
inflammation of the
gums.
