For hemorrhoids, everyone has heard a lot, but the scientific knowledge of hemorrhoids still needs a more detailed understanding. There are many causes of hemorrhoids. Sitting for a long time, standing for a long time, fatigue, etc. make the human body stay in a fixed position for a long time, which affects blood circulation, slows blood flow in the pelvic cavity and congestion of abdominal internal organs, causing excessive hemorrhoidal vein filling, varicose, and bulge One of the important causes of hemorrhoids caused by the tension of the vein wall is decreased. If exercise is not enough, bowel movement slows down, stool descends slowly or due to habitual constipation, which compresses the veins, causes local congestion and blood return obstacles, causes hemorrhoids intravenous pressure to rise, the resistance of the vein wall decreases, and can also lead to the incidence of hemorrhoids Increase. According to the analysis of clinical observations and statistical census results, there are significant differences in the prevalence of patients with different occupations. The prevalence of clinical officials, car drivers, salespersons, and teachers is significantly higher.
The hemorrhoids located in the mucous membrane of the anus are called "internal hemorrhoids", and the hemorrhoids located near the inner side of the anal opening are called "external hemorrhoids". The symptoms of hemorrhoids are pain in the affected area and blood in the stool. In severe cases, the hemorrhoids will bulge out of the anus (prolapse) and then retract after defecation.
According to the symptoms of hemorrhoids and the degree of harm to human health, internal hemorrhoids can be divided into four stages:
Stage I, no pain, mainly for blood, secretions, and itching; stage II, hemorrhoids prolapse during defecation, but can be repaid by itself; stage III (also called advanced stage), internal hemorrhoids prolapse in the anus Outside the mouth, or every time a bowel movement protrudes out of the anus, it cannot be repaid by itself, and it must be returned by hand. In stage IV, internal hemorrhoids protrude out of the anus and cannot be returned to the anus. This is the most serious disease in internal hemorrhoids.
Mild hemorrhoids bring inconvenience to people's normal life; severe hemorrhoids affect health. If the stool is bloody for a long time, it can cause different degrees of anemia, or even hemorrhagic shock, which is life-threatening; when hemorrhoids necrosis or infection is serious, it can cause systemic infection through the blood system, with serious consequences. Therefore, if you suffer from hemorrhoids, you must actively deal with it.
Severe hemorrhoids can cause or induce cardiovascular and cerebrovascular diseases, especially in elderly patients. If they suffer from hemorrhoids, they will have psychological pressure and dare not go to the toilet. If this happens, they will aggravate constipation. When it is difficult to defecate, the patient can hold his breath. The rapid heartbeat can cause cerebral blood vessels to rupture, causing cerebral hemorrhage or cerebral embolism; if internal hemorrhoids are incarcerated, the pain can also induce angina pectoris; if there is thrombosis, it can cause pulmonary embolism.
