How does haemorrhoid infect

summary

Due to the similar location of hemorrhoids and rectal cancer, many cases of rectal cancer are misdiagnosed as hemorrhoids at the initial stage. Clinically, 1% - 3% of the patients who came to the hospital due to hemorrhoids were finally diagnosed as rectal cancer. As a more complex disease, how can hemorrhoids be transmitted?

How does haemorrhoid infect

Reason 1: diet reason: in daily life, the diet rules or diet varieties inevitably change, which is very natural. For example, the quality of food, the variety and quantity of vegetables, the content of protein, fat, starch, cellulose, and water intake can directly affect the composition of feces, leading to anocecal diseases. People who drink alcohol for a long time or like to eat spicy food, because alcohol and spicy food can stimulate gastrointestinal mucosa, cause vasodilation, colon dysfunction, anorectal disease morbidity increased significantly.

The second reason: anal pad down: hemorrhoids is due to the anal support tissue degeneration caused by part of the mucosa and submucosal tissue down, first proposed the theory of mucosal sliding, then parks and Thomson made further development, put forward the anal submucosal "pad theory", anal pad (anal pad) Cushion is composed of dilated veins, smooth muscle, collagen fibers and elastic connective tissue. It can make the anal mucosa adapt to the changes of intestinal cavity size, and plays an important role in helping to close the anus and maintain the self-control of the anus. The degeneration of connective tissue and excessive defecation force can make the anal pad move down and cause hemorrhoid symptoms. Once the anal pad sags, it will inevitably lead to hemorrhoid vein return In addition to the influence of anal pressure such as constipation, pregnancy and other factors, it is also related to hormones, biochemical factors and emotions.

The third reason: vascular hyperplasia: the submucosal tissue of the tube is very thick. Bourgery compares it to "erectile tissue network" and calls it rectal cavernous body. It is composed of a large number of blood vessels, smooth muscles, elastic fibers and connective tissue. Like a circular air cushion, it helps to close the anus when the sphincter constricts. When the blood vessels in it proliferate and dilate to cause abnormal hypertrophy, hemorrhoids can be formed, but hemorrhoids can not be seen From the perspective of histomorphology, there is not enough evidence for the theory of vascular proliferation.

matters needing attention

This disease needs attention: normal people defecate once a day, defecate time has different habits of early, middle and after dinner. Normal defecation is formed soft stool, not dry not thin, defecation does not feel difficult, after defecation has a relaxed and comfortable feeling, which shows that the gastrointestinal function is excellent. If the constipation is hard, it is not only difficult to defecate, but also due to the accumulation of feces in the intestinal cavity, the increased pressure in the blood vessels of the anus and cecum, and the obstruction of blood return, the varicose hemorrhoids and venous plexus will deform and form hemorrhoids.
