There are many reasons why there is always a feeling of falling anus, the first one is more common in patients with long-term constipation, obstructed bowel movement, sometimes resulting in rectal stool retention, which sometimes produces a feeling of falling anus, and rectal palpation can palpate a large amount of feces, which should be treated with a cleansing enema in a timely manner. Secondly, if the patient has outlet obstruction type constipation, such as long-term rectal intussusception, rectal protrusion, which will lead to obstruction of fecal discharge, generally rectal protrusion indicates that the rectovaginal diaphragm is weak, should actively give anal dilatation, if necessary, perform fecal imaging, do surgery, can perform rectal mucosal resection or rectal protrusion repair. The third, if the patient had mixed hemorrhoids in the past, drinking a lot of alcohol or eating irritating food can induce swelling of the nucleus of the mixed hemorrhoids and aggravate the hemorrhoids, thus leading to a feeling of downward movement at the anal opening, you should actively give medication and conservative treatment, and if necessary, you can surgically remove the hemorrhoids.
