The recurrence rate of hemorrhoids after surgery is high, and there are many people who still have recurrence even after multiple surgeries. Although there are many reasons for this, patients fail to perform good self-conditioning and neglect anal function exercises, which is one of the important factors for recurrence of hemorrhoids after surgery. The normal physiological role of the anus is mainly expressed in the contraction and dilation of the anus. These functions are performed by the internal and external anal sphincters and the anal levator muscles under the innervation of the nervous system. Therefore, in a normal healthy person, the anal contraction and dilation are strong and moderate, and there are no symptoms of defecation difficulty or anal incontinence. In contrast, after hemorrhoid surgery, the anal sphincter has been damaged to varying degrees. Effective anal function exercise at this time can improve local blood circulation, reduce stasis and expansion of hemorrhoid veins, increase the contraction and diastolic capacity of the anal sphincter, enhance the resistance of the anorectal area, and avoid and reduce the recurrence of hemorrhoids. For patients with incomplete anal incontinence, anal functional exercise is especially important. Patients with post-operative hemorrhoids should exercise under the guidance of a doctor according to their condition. Exercise should be consistent and avoid being rushed and causing excessive fatigue. When exercising, it is better to feel comfortable.
