1, what is hemorrhoids Hemorrhoids are soft venous masses formed by the expansion and flexion of the venous plexus under the mucous membrane at the end of the human rectum and the skin of the anal canal, a common anorectal disease, also known as hemorrhoids, hemorrhoids, hemorrhoids, hemorrhoid disease, etc.. It can develop at any age, but the incidence gradually increases with age. In our country, hemorrhoids are the most common anorectal disease, and there are “nine hemorrhoids in ten men” and “ten hemorrhoids in ten women”. 2, the cause of hemorrhoids (1) anatomical factors rectal vein cavity without venous valves, blood is easy to stagnate, rectal submucosal tissue relaxation, lack of support for the venous plexus, the pressure of the fecal mass and are the factors that lead to varicose veins, the formation of hemorrhoids to unscrape. (2) Increased intra-abdominal pressure where constipation, urination disorders, pregnancy, intra-abdominal masses and other factors can increase intra-abdominal pressure, affecting venous reflux. (3) Other factors systemic weakness, long-term malnutrition caused by the weakness of the venous wall; chronic infection of the lower rectum and anal canal, so that the venous wall fibrosis loss of elasticity; long-term constipation, diarrhea, cough, alcohol, spicy and irritating food, pregnancy and childbirth, sedentary and sedentary, etc. can cause the occurrence of hemorrhoids. 3, the high incidence of hemorrhoids people (1) often in a standing and sitting position of the highest rate of hemorrhoids. Such as drivers, text workers, typists, waiters, students, porters and other relatively high incidence. (2) Patients with constipation, especially stubborn constipation, chronic diarrhea, cough, liver cirrhosis, etc. (3) addiction to spicy, fatty, sweet and thick or too fine and refined food. (4) poor defecation habits: long defecation time, inattention such as reading books and newspapers and playing with cell phones. (5) Pregnant women: pregnant women have increased blood flow in the pelvic arteries, and the uterus compresses the pelvic cavity, so that the return of blood in the hemorrhoid vessels is blocked. 4, the symptoms of hemorrhoids (1) blood in the stool: patients often find blood dripping into the urinal or stained blood on the stool paper. The heavy case is jet-like, can be caused by excessive force during defecation rubbing the mucous membrane, blood in the stool can stop on its own. If long-term bleeding can lead to severe anemia, life-threatening. (2) Prolapse: In mild cases, the hemorrhoid can be prolapsed during defecation and can be retracted by itself after defecation; in severe cases, it can be retracted by hand, otherwise the prolapsed hemorrhoid can be embedded. In severe cases, the hemorrhoid can come out when the patient walks, coughs, etc. to increase the abdominal pressure. (3) Pain: Pain is felt when the hemorrhoid is damaged and infected or when a thrombus is formed, and when the internal hemorrhoid and mixed hemorrhoid become embedded and become edematous, infected, or necrotic, the local pain is intense. (4) Itching: When the hemorrhoid is prolapsed, the mucus secretion flows out and stimulates the perianal skin, causing itching or even skin eczema. 5.Treatment of hemorrhoids Patients with mild bleeding or pain can be treated conservatively with drugs, and surgery is needed when bleeding is severe or prolapse or swelling and pain is obvious.
