The anus has no contractive force, that is, the anal sphincter relaxes and will be accompanied by fecal incontinence. In this case, the anus can be lifted in the morning and in the evening. When inhaling, the anus can be lifted up, holding for a few seconds, and when exhaling, the anus can be relaxed. This exercise can promote the contractive ability of the anal sphincter. Severe anal relaxation without contractive force requires surgical treatment, and ligation, rubber ring ligation and other operations can improve the symptoms of anal relaxation. Pay attention to diet at ordinary times, avoid spicy and stimulating food, eat more food with high dietary fiber content, promote intestinal peristalsis, prevent constipation, and use warm water hip bath every day to promote local blood circulation, which can enhance the function of anal sphincter.
