what does a hemorrhoids look like,What causes fecal incontinence

    There are many reasons for fecal incontinence, which can be divided into congenital and acquired factors according to the time of onset.

    1. Congenital factors: congenital absence of sphincter, incomplete anorectal ring development and spinal injury.

    2. Acquired factors:

    (1) Operational injury factors: Anorectal surgery is a part of general surgery. Although the scope of operation is relatively small and the risk is relatively low, improper operation can cause irreversible damage and cause great physical and psychological pain to the patient. Such as high perianal abscess, high anal fistula and other local anatomy is not clear, rough surgery to cut off the anorectal ring, or excision of surrounding tissues and skin too much, after healed to form a deeper scar groove, resulting in lax closure of the anus. The anus loses its sphincter function. In hemorrhoid surgery, if you inject irritating drugs, such as necrotic agents and sclerosing agents, the injection concentration is too large, the medicine is too concentrated, and the site is too deep. Or take the treatment of hemorrhoids and apply strong corrosive drugs, which can cause widespread local anorectal infection or large-scale deep burning, causing mucosal sclerosis, necrosis, or scarring of the anorectal ring, leading to varying degrees of fecal incontinence; anal fissure Anal expansion therapy under anesthesia, if excessively strong anus expansion causes a sudden rupture of the anorectal ring, or third-degree perineal tear during childbirth, it can cause the sphincter to lose its sensitive sphincter ability and cause fecal incontinence; in addition, long-term severe prolapse or internal hemorrhoids , Make the sphincter muscle fatigue, reduce the tension, relax anus and cause fecal incontinence.

    (2) Nerve injury factors: thoracic and lumbar spine decompression paraplegia or surgery and other diseases cause sacral nerve or pudendal nerve damage, which makes the muscle lose its innervation, and the sphincter cannot contract normally; stroke and sudden shock can also cause temporary fecal incontinence.

    Traditional Chinese medicine believes that fecal incontinence is caused by the decline of qi and blood, insufficient qi, sinking of qi deficiency, inability to close the anus, or "traumatic" or "incurable".
