The number of people who suffer from hemorrhoids is large, and there is a saying that “nine out of ten hemorrhoids”, and the age of onset of hemorrhoids can range from a few years old to dozens of years old. These questions have been plagued by many people, today we will do a little interpretation. First of all, we must understand what is hemorrhoids Hemorrhoids is the end of the rectum under the mucous membrane and the skin of the anal canal under the venous plexus to expand, varicose soft vein mass formed. In layman’s terms, it is a small vein at the anus that dilates under certain factors, causing the skin at the anus and the mucous membrane at the lower end of the rectum to bulge or prolapse. Are hemorrhoids hereditary First we need to understand what a genetic disease is. Genetic diseases are diseases caused by changes in the genetic material and are diseases that can be passed from parents to children. There is a theory that hemorrhoids are genetically related, that the veins of some patients are more prone to varicose and form hemorrhoids under the action of external forces than those of other people, and that according to this principle, patients suffering from hemorrhoids should have a much higher risk of suffering from varicose veins, but from the clinical point of view, there are no such cases. So instead of saying that hemorrhoids are related to heredity, it is more related to family life and dietary habits. Are hemorrhoids contagious So what are infectious diseases? Infectious diseases are diseases caused by pathogens that can spread from person to person or animal to animal. Pathogens are bacteria, viruses, parasites, and other organisms that can cause infectious diseases, and one of the first requirements for an infectious disease is the spread of the pathogen. Hemorrhoids are soft clusters of veins formed when the venous plexus under the mucous membrane at the end of the rectum and under the skin of the anal canal becomes enlarged and varicose, and are not caused by pathogens. So please rest assured that hemorrhoids are definitely not contagious. What are the other causes of hemorrhoids 1. constipation In the state of constipation, we squat toilet time is too long or hard to defecate will make the abdominal pressure increase, impede the venous blood return, the blood filled rectal venous plexus, resulting in the venous plexus blood vessels gradually dilated, the formation of hemorrhoids. The onset of constipation is mostly related to the life of diet too fine and small amount of fiber intake is insufficient, when there is a desire to hold back or not regular defecation and other habits. 2. Anatomical reasons Our body’s veins have venous valves, the role of venous valves is to prevent the role of gravity blood retrograde, prompting the blood to return to the heart; but there is no venous valves on the rectal veins, so when a person is standing for a long time sitting by gravity, the rectal veins of the blood stagnation in the end of the rectum, the formation of hemorrhoids. 3. old and weak With the increase in age, the body organs, systems also face the problem of aging, vascular smooth muscle relaxation, elastic fiber atrophy, blood vessels are more fragile than young people, easy to form hemorrhoids. 4. Pregnancy and childbirth factors After pregnancy, the uterus increases in size as the fetus grows, and the enlarged uterus presses on the veins, causing obstruction of venous blood return and blood stasis. In addition, the activities of pregnant women are reduced, the gastrointestinal peristalsis slows down, the stool in the intestinal tract stays for a long time, in which the water is easily absorbed, so that the stool becomes lumps and hard knots, resulting in constipation, which aggravates the degree of stasis of blood in the anal veins, resulting in the expansion of the venous blood vessels in the anus, which is twisted and develops into hemorrhoids. 5. Occupational factors According to the domestic survey found that the onset of hemorrhoids and occupation has a certain relationship, such as shopkeepers, barbers, and other people engaged in long standing; sandblasters, and other people engaged in long squatting work; bank employees, typists, drivers and other people engaged in sedentary work, the incidence of hemorrhoids in these people is higher. In order to reduce the occurrence of hemorrhoids, we should usually develop good defecation habits, defecation time should not be too long, to prevent dry stools, try to avoid long standing and sitting. Change the family bad dietary habits, you can say goodbye to hemorrhoids, happy life every day!
