A lot of friends for anal disease awareness is limited to hemorrhoids, think hemorrhoids is all anal disease, but you do not know is that there are more than 100 common types of anal disease. There are four kinds of common, also known as the “four kings” of the anorectal world. Today we’ll introduce them. The boss – hemorrhoids Hemorrhoids are the most prevalent of all anal diseases, accounting for more than 59%, including internal, external and mixed hemorrhoids. Common symptoms of hemorrhoids: Blood in the stool, constipation, prolapsed hemorrhoid nucleus, bleeding due to friction by feces during defecation and rupture of the ulcerated surface, which does not blend with the stool, bright red, or even ejected from the anus. Internal hemorrhoids can become embedded as they prolapse out of the anus. Hemorrhoids harm: Anemia, long-term blood in the stool will occur dizziness, palpitations, weakness, sleepiness and shortness of breath; will also cause mental burden, seriously affecting a person’s work life; induce other anal diseases, and even deteriorate into cancer! Second – Anal fissure Anal fissure is a common anal canal disease that occurs in young adults and is more common in women than men. Anal fissures are caused by excessively dry and hard stools and excessive force in defecation. Women commonly use force during pregnancy and injure the anal skin muscles. Anal fissure symptoms: Pain is the most prominent symptom of anal fissure, which is intense, persistent, and regular. Blood in the stool is easy to occur when the stool is dry and hard, the amount of blood is small, bright red, and there is no blood spraying, usually only a small amount of blood on the tissue when wiping. Anal fissure hazards: Anal fissure is an infected ulcer, improper or untimely treatment can cause sentinel hemorrhoids, anal sinusitis, anal papillomegaly, anal fistula and other diseases. Older three – anal fistula An anal fistula refers to a fistula formed by the rectum, the anal canal and the surrounding skin. An anal fistula is usually composed of an internal port, a fistula tube, and an external port. Most of the internal openings are located near the dentition line, mostly one, and the external openings are located on the skin around the anus and can be one or more. Symptoms of anal fistula: recurrent localized pus, pain, itching, and palpable or detectable fistula leading to the rectum. The danger of anal fistula: pus and feces contamination of clothing and pants, causing a series of anal skin conditions such as itching and eczema, decreased immunity, poor mental status, anemia, etc. Older four – perianal abscesses Abscesses mostly come from the perianal gland infection and pus spread to the perianal canal gap or the abscess formed under the skin and mucous membrane of the anal canal. Symptoms of perianal abscess: A small hard lump or mass around the anorectum, unbearable local pain, redness, swelling, heat, swelling and discomfort, restlessness, urgency, constipation, poor urination, rectal irritation, and subsequent symptoms of systemic toxicity such as elevated body temperature, loss of appetite, chills, weakness, etc. Perianal abscess harm: itching: pus will flow out when the abscess breaks down, which will stimulate the perianal skin and cause itching, and the itching will intensify at night, and the resistance of the body will decrease, and symptoms such as weakness, general weakness, restlessness and depression will appear. Perianal abscess will evolve into anal fistula at a later stage. If you find several situations above, don’t panic and go to the hospital in time is the right way. In order to avoid causing harm to the body and affecting life and work.
