The incidence of hemorrhoids is 70-80%. There is a popular saying that “nine out of ten people have hemorrhoids”. However, there are often many misconceptions about this common condition. 1, snapper can treat hemorrhoids for varicose veins mixed hemorrhoids, or bleeding internal hemorrhoids, eating snapper has some effect, but for connective tissue external hemorrhoids, eating snapper is useless. 2, freezing treatment is good and should be preferred Modern freezing technology for hemorrhoids does open up a new way for hemorrhoids and is more effective. However, cryotherapy is only suitable for internal hemorrhoids and sometimes leads to haemorrhage after surgery due to tissue necrosis. Therefore, the choice of cryotherapy should be based on the condition, and the latest method may not be the best one. 3, hemorrhoids are good recurrence, surgery is also useless not right. Although hemorrhoids are a disease with a high recurrence rate, they by no means do not require surgery. Some hemorrhoids have serious symptoms and are difficult to treat, so the only way to achieve clinical cure is through surgery, and as long as you pay attention to post-operative care, you can prevent recurrence. 4, hemorrhoid surgery can cause fecal incontinence this is no basis for rumors. Surgery for hemorrhoids will not lead to fecal incontinence as long as it is done correctly. 5, hemorrhoids can become cancerous, this claim makes some hemorrhoid patients worried. In fact, modern medicine has not yet confirmed the possibility of hemorrhoids becoming cancerous, so there is no need to worry about this. However, the early symptoms of rectal cancer are often similar to those of hemorrhoids, which sometimes leads to misdiagnosis of rectal cancer and delays in treatment, so attention should be drawn to this. 6, nine out of ten hemorrhoids, no need to go to treatment this view is wrong. The reason for this is that you can’t get rid of the hemorrhoids that are not showing symptoms, but if you have symptoms such as bleeding, prolapse, and pain, you can only aggravate your pain and cause health hazards. 7, one injection, never relapse This is often seen in some irresponsible advertising words, saying that the use of internal hemorrhoid sclerotherapy injection treatment, will not relapse. This is not true, internal hemorrhoid sclerotherapy injection therapy, sometimes can stop bleeding for six months. The reason for the onset of hemorrhoids 1, the physiological structure of the defects and upright position: the human body standing or sitting straight, the anal position is low, subject to the influence of gravity, rectal-anal venous blood reflux obstacle, rectal veins and their branches lack of venous valves, blood is prone to stasis, and rectal blood vessels are arranged in a special way, in different planes through the muscle layer vulnerable to fecal pressure, so that the veins in the loose tissue under the mucosa are prone to expand, varicose and Hemorrhoids are produced. This is why it is said that hemorrhoids are a disease unique to the human body. Reptiles such as cows, horses, dogs and rabbits do not suffer from hemorrhoids, mainly because of the high anal position of reptiles, which facilitates the return of blood to the anorectal area and is less likely to produce varicose veins in the anorectal area. In addition, near the dentate line, tiny arteries and veins directly anastomosing and forming cavernous veins, cavernous veins with poorly developed muscular layer, less elastic fibers and more collagen fibers, easily expand and form hemorrhoids. 2, constipation: long defecation time or long-term diarrhea, can make the abdominal pressure increased, anorectal congestion, varicose hemorrhoid veins, and can even lead to the separation of rectal mucosa and muscle layer prolapse, the anal canal with the feces down, for a long time easy to produce hemorrhoids. 3, infection factors: anal sinusitis, anal gland infection, perianal abscess, dysentery, enteritis, intestinal parasitic disease, colitis, etc., can cause inflammation of the tissue around the lower rectum, hemorrhoidal vein involvement, inflammation, so that the wall of the hemorrhoidal vein becomes brittle, followed by vasodilatation and congestion and cause or aggravate hemorrhoids. 4, pregnancy and childbirth: pregnant women, fetal compression of the pelvic veins, so that venous reflux is blocked, the anorectal part of the vasodilatation, and at the same time, due to the rise in the body progesterone content, resulting in water and sodium retention, vasodilatation and induced hemorrhoids. 5, anal sphincter relaxation: old and frail and repeated anal surgery and destruction of the complete structure of the sphincter patients, because of the sphincter muscle weakness to make hemorrhoids prolapse aggravated. 6, portal hypertension: hepatic sclerosis, portal vein thrombosis, etc., can cause portal hypertension, due to the lack of venous valves in the portal venous system, can directly lead to increased pressure in the hemorrhoidal venous plexus, causing hemorrhoids. 7, tumors: abdominal and pelvic tumors, such as colon and rectal tumors, ovarian tumors and uterine fibroids can compress the pelvic veins, so that hemorrhoidal venous reflux is blocked and hemorrhoids are produced. 8, genetic factors: about genetic factors, western medical views are not uniform, need further verification. Some people believe that the higher incidence of hemorrhoids in a family may be related to genetic factors. In conclusion, modern medicine believes that the factors that produce hemorrhoids are complex and may also be the result of the interaction of several of the above factors.
