If the sphincter is strained, the protective function of the inner part of the anus decreases, and once it is damaged, external bacteria and viruses may enter the anus, causing inflammatory lesions inside the rectum and even perianal diseases. In addition, surgery on the anal area may cause strain on the sphincter muscle, and the main manifestation of the strain is impaired bowel discharge control, which may increase the number of bowel movements, that is, the ability to control bowel movements may be reduced, and even fecal incontinence may occur. If the sphincter is strained, the control of the anal canal will be reduced, which will affect the normal anal closure and cause the inability to defecate on one’s own, even if there is no sense of defecation, the phenomenon of leakage will occur. Therefore, if the above-mentioned symptoms are not relieved within a short period of time, you must go to a regular hospital in time to further improve the relevant examination and choose a reasonable rehabilitation method to help early recovery.
