Elderly people have the intention to defecate but cannot do so, mostly because along with the increase of age, the elderly have less food and significantly less activity, and eat too fine, containing insufficient crude fiber, resulting in the peristaltic function of the gastrointestinal tract is weakened. As their strength decreases, the strength of their abdominal and pelvic floor muscles decreases, as does the strength of the internal and external anal sphincter muscles, resulting in constipation as food stays in the intestines for too long and water is excessively absorbed, resulting in dry stools and a weakened force to expel them outward. These patients need to adjust their diet, increase physical exercise, and consciously cultivate good bowel habits to relieve their symptoms.
