The formation of hemorrhoids is usually considered to be due to the expansion of the submucosal venous plexus of the distal rectum and the subcutaneous anal canal. As the saying goes, "ten people nine hemorrhoids", poor living habits, defecation time is too long, squatting toilet for too long or occupational reasons can increase abdominal pressure, leading to varicose veins, poor blood flow and the formation of hemorrhoids.
People who like tobacco and alcohol, spicy diet, usually less exercise, fast pace of life, mental pressure, etc., are also the culprits of hemorrhoids, which is the external reaction of long-term bad living habits slowly formed in the body.
However, in addition to the above bad habits, the real cause of hemorrhoids is often caused by a variety of factors, mainly the following theories, such as the anal pad down theory, varicose vein theory, etc. At present, it is agreed that due to the destruction of the normal fibroelastic structure in the anal pad accompanied by varicose veins in the anal pad and chronic inflammation and fibrosis, the pathological hypertrophy of the anal pad and the formation of hemorrhoids after the distal displacement.
Therefore, hemorrhoids is a common disease in anorectal diseases, frequently-occurring, mostly in the working men and women in the 30-50 years old age group. Serious disease is often not overnight, but in the patient\'s patience, little by little accumulation, unconsciously evolved. If it is taken care of at an early stage and managed effectively, the physical and mental pain of many patients will not be reduced by more than a little.
