Hemorrhoids, an unfamiliar and familiar word, some people have been with it for a long time and suffer in silence; some people just hear about it and don’t yet know why it torments them! Why do some people have hemorrhoids and others do not? This can not get hemorrhoids, in fact, and heredity, lifestyle habits, gastrointestinal health, age and other factors are related. Therefore, these 4 types of people are more likely to be hemorrhoids “favor”, become “hemorrhoids” of the people. 1, sedentary, standing still, overweight, pregnant people First of all, some bad habits are easy to suffer from hemorrhoids. For example, sedentary standing, some occupational groups need to stand for a long time or sedentary or long-term weight-bearing long-distance travel, affecting venous return, so that the pelvic blood flow is slow and intra-abdominal organs congested, resulting in hemorrhoidal venous overfilling, decreased venous wall tension, blood vessels are prone to stasis expansion, so that the anal mucous membranes are congested with hematoma and edema. Or because of the lack of movement, intestinal peristalsis is reduced, feces downward slow, or habitual constipation, increased intra-abdominal pressure leads to the occurrence of hemorrhoids. There is also the habit of long-term squatting, but also easily lead to blood reflux obstruction and stagnation, the formation of hemorrhoids. Secondly, is pregnant women, due to the gradual increase of the uterus, will compress the rectum, anal veins, intra-abdominal space becomes smaller, higher pressure leads to blood reflux is blocked, also easy to form hemorrhoids, and the more times a woman is pregnant, the higher the incidence of hemorrhoids. In addition to being affected by the increase in the uterus, it is also related to the fact that the elevated hormone levels in pregnant women cause the blood vessels near the anus to relax and become engorged. During pregnancy, the uterus will press on the blood vessels and nerves, poor blood circulation, resulting in constipation appeared, especially before the fast delivery, the fetus is getting bigger and bigger, prolapse of the anus also occurs, so some pregnant women often suffer from constipation, hemorrhoids. 2, constipation, diarrhea crowd When the anus and rectum, cold, heat, constipation, diarrhea, excessive alcohol and spicy food stimulation, hemorrhoidal venous plexus is more likely to be congested, affecting the venous blood return, so that the venous wall resistance to decline, resulting in hemorrhoids; diarrhea, constipation can increase the vertical pressure of the anal cushion of the push, so that the Treitz muscle overextended, rupture, resulting in the anal cushion of the downward displacement and contribute to the occurrence of hemorrhoids. The 3, middle-aged and elderly people hemorrhoids is the most common anorectal disease, the onset and age has a certain correlation, and with the increase in age and the upward trend. Ageing makes the Treitz muscle began to degenerate, there is relaxation, fracture, began to appear senile degenerative changes, support tissue relaxation, anal cushion has a tendency to protrude from the anal canal cavity; the surrounding tissue elastic fiber reduction, anal cushion retraction obstacles, from the original fixed in the position of the internal sphincter moved, resulting in the anal cushion downward, and the occurrence of hemorrhoids. Among the 45-65-year-old crowd, more likely to become “hemorrhoidal people”. Many elderly people due to age factors, abdominal blood circulation is not good, the anal part of the venous blood vessels are prone to local expansion, flexion, the formation of venous mass. In addition, the old and weak people elastic retraction force is reduced, can also lead to the occurrence of hemorrhoids. 4, there is a family history of people Now is not sure of the heredity of hemorrhoids, but from the census results and clinical history shows that hemorrhoids patients have familial, which may be related to the habits of life and so on. Hemorrhoids may also occur if there is congenital weakness of the vein wall, which has reduced resistance to pressure and cannot tolerate high intravascular pressure, and gradually dilates.
