A, about the causes of hemorrhoids: 1, some say: hemorrhoids, is the price paid by humans walking upright. The pressure of the pelvic floor venous reflux is greatly increased after the person is upright, leading to the stasis and expansion of the veins of the perineal pelvic floor and hemorrhoids. 2, the characteristics of the anatomical structure is also one of the factors of the high incidence of hemorrhoids. The veins of the pelvic floor do not have venous valves and cannot bear the pressure of the upper veins in a graded manner. The pressure of the vena cava is transmitted directly to the pelvic floor, while the increased pressure of abdominal pressure (such as coughing, weight bearing, etc.) is also transmitted directly downward, leading to varicose veins. 3.Women are the important cause of morbidity because of pregnancy, childbirth and other special physiological processes, which is also the reason for their higher chance of morbidity than men. After pregnancy, as the fetus grows, abdominal pressure increases, the inferior vena cava is pressurized, affecting the blood return, resulting in congestion and expansion of the hemorrhoidal plexus; coupled with childbirth, the perineum is damaged to varying degrees, aggravating the venous reflux disorder, thus triggering hemorrhoids and many anorectal diseases. 4, the occurrence of hemorrhoids and sex hormone levels are closely related to the rectal submucosa has a spongy sinus-like structure, which is affected by sex hormones and the occurrence of congestion and edema and other pathological changes, the level of sex hormones increases in adulthood and leads to the occurrence of hemorrhoids, so hemorrhoids are common in adults. 5, sedentary, sedentary, long-term single posture and activity less people suffering from hemorrhoids: from the occupational analysis of drivers, hairdressers, salesmen, civilian police and other incidence rate of 81.7%, followed by cadres for 71.5%, workers for 70.3%, farmers for 62%, soldiers for 32.6%, students for 19.2%. 6, abnormal bowel habits is an important cause of hemorrhoids: constipation, diarrhea is the response to intestinal dysfunction, which can directly cause anal congestion and edema and skin mucosal damage, causing the anal cushion reticular fibers to break and move down to form hemorrhoids. 7, bad diet is also an important factor in the occurrence of hemorrhoids, which directly stimulates the intestinal mucosa, causing congestion and edema of the intestinal wall and chronic inflammation, which in turn leads to hemorrhoids. 8, chronic abdominal pressure increase in the disease is also one of the causes. Such as chronic cough, croup, asthma, prostate hypertrophy, constipation, etc., so that the abdominal pressure is in a high state for a long time, the pelvic floor venous reflux resistance increased triggered hemorrhoids. Second, prevention: understanding the causes of the disease can help us target prevention. 1, prevention of infection, enhance body resistance; 2, avoid alcohol or less alcohol, avoid spicy and stimulating food; 3, work habits can be changed, you can regularly change posture, work between activities, kicking legs, stretching waist; 4, timely treatment of chronic diseases and constipation, diarrhea and other diseases; 5, massage small belly, conducive to intestinal peristalsis; 6, anal lifting exercises to strengthen the sphincter and support structures around the anal canal; 7, active treatment of chronic diseases and constipation, diarrhea and other diseases; 8, massage small belly, conducive to intestinal peristalsis; 6, lifting exercises to strengthen the sphincter and anal canal; 7 8, active treatment of chronic diseases; 8, there is another important point: life is exercise, exercise can prevent the occurrence of many diseases. Most patients as long as they adhere to self-care, pay attention to timely treatment, the effect is very good, it is important to adhere to.
