The cause of hemorrhoids is currently unknown, but may be related to a variety of factors, the current often mentioned there are two causes of the doctrine: the doctrine of anal pads downward displacement and varicose veins doctrine.
The doctrine of anal cushion downward displacement: there is a ring-shaped vascular cushion on the inner side of the anal canal, called the anal cushion, which is composed of a rich network of venous blood vessels, smooth muscle, connective tissue, and plays a role in the closure of the anal canal and the control of defecation. During defecation, the anal pad is pushed downward by downward pressure, and then contracted back to the anal canal after defecation.
When the elasticity of the anal pads retraction role is weakened, congestion occurs, downward and hyperplasia hypertrophy, over time the formation of hemorrhoids.
Varicose veins doctrine: the anal cushion is rich in venous plexus, no venous valve, and is located in the lowest part of the abdominopelvic cavity, the surrounding tissue relaxation, easy to make the venous plexus congestion, bruising, and pressure to form varicose veins. Such as long-term standing, sedentary, pregnancy, prostate hypertrophy and other factors, resulting in varicose veins, hemorrhoids are more likely to occur.
Predisposing factors for hemorrhoids are often caused by poor bowel habits, such as prolonged bowel movements, or low-fiber diets, long-term constipation, diarrhea, and so on. Bleeding, perianal itching, prolapse, pain, swelling and other clinical manifestations may occur.
Once discovered, it is recommended to go to the anorectal department of the hospital in time for consultation and examination, and take appropriate treatment under the guidance of the doctor. Daily attention to keep the perianal environment clean and clean, to ensure that the intake of fiber food, light diet, avoid spicy stimulating food, regular monitoring of symptomatic changes.
