Old Zhang is a car driver, usually busy, no time to read books and newspapers, so he developed a habit, every time you take a few newspapers or magazines, sitting on the toilet while reading, often the more fascinated, less than ten minutes, more than half an hour or even longer, causing the family outside the toilet straight knocking on the door. But recently he found that after each stool there is blood on the hand paper, and sometimes even dripping blood. In recent days, the anal opening is swollen and painful, itching, and soft masses come off. So old Zhang rushed to the hospital to see a doctor, after examination turned out to be hemorrhoids, and quite powerful. The actual fact is that you will be able to get a lot more than just a few of the most popular and popular items. In fact, hemorrhoids, commonly known as hemorrhoids, is one of the most common human diseases, people have the so-called “ten people nine hemorrhoids”, or even “ten men nine hemorrhoids, ten women ten hemorrhoids” said. Hemorrhoids are the tortuous expansion of the submucosal venous plexus of the skin of the lower rectum and anus. When a person is upright, the lower rectal and anal plexus is located very low, the role of gravity increases the venous pressure, blood flow back is blocked, and over time, it is easy to cause varicose veins, and the tortuous formation of the masses protruding from the mucosal surface of the skin. The animals like dogs and pigs that are on all fours rarely have hemorrhoids because of their high anal position. Hemorrhoids can be divided into internal, external and mixed hemorrhoids depending on where they occur. Internal hemorrhoids are very common and usually occur at the recto-anal junction – above the dentate line. Mild internal hemorrhoids do not prolapse out of the anus and mostly show fresh blood after a bowel movement, while moderate to severe internal hemorrhoids can have hemorrhoids that prolapse out of the anus. Sometimes with bacterial infection there will be anal edema and pain, and the hemorrhoid mass cannot be returned. Rectal mucosal secretions can irritate the skin around the anus and cause itching and discomfort. External hemorrhoids occur below the dentate line and are mostly connective tissue external hemorrhoids, which appear as a fleshy bulge at the edge of the anal opening, commonly known as a “skin sag”, and are generally not uncomfortable. Mixed hemorrhoids are a combination of both. As hemorrhoids are a unique human disease, it is important that people develop good habits to prevent it. Eat less spicy and irritating food, don’t smoke or drink, avoid standing and sitting for long periods of time, eat more vegetables and fruits and roughage, and have regular bowel movements and keep them open. Dry stools or prolonged bowel movements can aggravate varicose hemorrhoids, and even soft stools may then rub the blood vessels and cause bleeding. It is not surprising that a long period of time while reading a book, like the old man, while defecating will soon cause a hemorrhoid attack. The majority of patients can be relieved by non-surgical treatment, including oral anti-inflammatory, hemostatic and laxative medications, local anal use of hemorrhoid creams and suppositories, and warm water sitz baths after the bowel movement. A small number of patients with severe or frequent recurrence can be treated surgically. It should be noted that hemorrhoids are not cancerous, but rectal cancer is easily misdiagnosed as hemorrhoids. Anyone who encounters recurrent blood in the stool with mucus or pus should go to the hospital for anorectal examination or anorectoscopy, and if necessary, colonoscopy.
