Why do many people have a small pimple on the outside of the anus? In fact, there are many possible causes, which are related to genetic factors. Congenital weak vein walls can also cause this kind of situation. The part is stimulated, or because the professional relationship is connected for a long time, it should be paid attention to in life.

　　In fact, the toxins of the human body are every day Need to be discharged, and also need to pass through the anus during discharge, that is because many people will find a small pimple outside their anus, and this small pimple does not actually have itching or pain, but it still remains Let everyone feel worried, so why is there a small pimple outside the anus?
　　First, anatomical factors
　　People are standing or sitting, and often the lower part of the anus will be intravenously injected into popular obstacles because of the pressure of gravity. The blood in the rectal vein cannot be recovered quickly, and it is easy to stagnate. In fact, the arrangement of blood vessels is very special. It is easy to be pressed by feces and affect the blood return. The veins are more likely to expand after passing through the loose mucosa in the submucosa.
　　Secondary genetic relationship
　　The vein wall is congenitally weak, so the resistance will gradually decrease, and it cannot tolerate the pressure in the blood vessel, so it gradually expands, and it is easy to expand after expansion It can cause small pimples on the outside of the anus, but in such cases, basically no obvious pain, or other phenomena.
　　Three, professional relations
　　Because of professional relations, some people may sit for a long time, or they may be burdened and travel far, affecting venous return, resulting in blood in the pelvis Slow flow, congestion of internal organs in the abdomen, causing excessive filling of the hemorrhoidal veins, which is more likely to cause expansion. If you do not receive exercise as soon as possible in your life, reduce bowel movements, slow down the stool, or have constipation for a long time, you can oppress and stimulate the veins, and it will also increase the chance of small pimples.
　　Four local irritation
　　If the anal area is stimulated by hot and cold, it may be bothered by constipation and diarrhea, all of which can stimulate the anus and rectum to make Congestion of the hemorrhoidal venous plexus will also affect the return of venous blood to a certain extent, resulting in a decrease in the resistance of the venous wall. If such conditions are not improved in time, small pimples will occur.
