The aging gut: physiology.
Changes in the physiology of the gastrointestinal tract with aging are less obvious than are seen in other organs, such as the brain. Nevertheless, physiologic changes play a role in the anorexia of aging, postprandial hypotension, aspiration pneumonia, increased Clostridium difficile infections, fecal incontinence, gallstones, and altered drug metabolism.
