The role of lifting the buttocks and contracting the anus includes reducing the incidence of hemorrhoids, alleviating constipation, preventing anal sphincter dysfunction, and reducing incision edema after hemorrhoid surgery. 1. Lifting the buttocks and contracting the anus can exercise the anal sphincter and pelvic floor muscles. 2. Hemorrhoidal patients with engorged and dilated veins in the anal canal or lower rectum can enhance blood circulation around the anus by performing anal retraction exercises, thus accelerating venous return. The exercise can reduce venous dilatation, which in turn can prevent hemorrhoids as well as reduce the symptoms of hemorrhoids. 3. By exercising the anal sphincter and pelvic floor muscle groups, it increases the control of the perianal muscles, reduces the occurrence of fecal incontinence, and prevents anal sphincter disorders. At the same time can also make the blood circulation around the anus function to improve, strengthen the rectal contraction ability, conducive to the discharge of stool, so lift the buttocks and shrink the anus exercise can also relieve constipation. 4. When the patient after anal surgery, often carry out hip contraction exercise, can make the anal sphincter to get exercise, incision edema absorption speed will be accelerated, so as to play a role in reducing the role of incision edema after anal surgery. Perianal discomfort, it is recommended that timely medical treatment, standardized treatment under the guidance of a professional doctor, so as not to delay the condition.
