In the elderly, the history--including dietary habits, onset, duration, and change in bowel pattern--is very important. Recent changes could suggest bowel disease such as carcinoma or a disordered metabolism. If the defecation stimulus is repeatedly denied by voluntary contraction of the external anal sphincter, the normal defecation reflex may be blunted and, in time, completely lost.
对于老年人来说，病史——包括饮食习惯、发病情况、病程以及排便习惯的改变——非常重要。近期的变化可能提示肠道疾病，如癌症或代谢紊乱。如果通过肛门外括约肌的自主收缩反复抑制排便刺激，正常的排便反射可能会减弱，久而久之甚至完全丧失。
