The anus must be closed tightly and drip-proof. In addition to the main "coarse control switch" of the anal sphincter, it also needs the "fine adjustment switch" of the "anal cushion" (the "sponge body" formed by the venous plexus in the anal canal). The pressure in the anus is adjusted quickly and finely through the "volume of blood" in the venous plexus in the anal cushion, which ensures that the "asshole" does not leak air or water. However, when there are obstacles in the following three aspects: 1. Pressure overload in the rectum; 2. Decreased anal sphincter strength; 3. Disorder of the anal neuromodulation reflex system. Over time, the "vascular plexus" of the anal cushion will expand and thicken compensatoryly, bulging into a "grape ball", which is called "hemorrhoids" at this time.
Therefore, at this point, we must first clarify a problem: "hemorrhoids" are effective, and their role is to "complement" the problem of pressure regulation in the anus, and prevent "gas running out of scum". The expansion and hypertrophy of the venous plexus of the anal cushion, bulging up like a "grape"-like meat ball (below), called "hemorrhoids".
When the anal cushion begins to form grape-like "hemorrhoids", it is not visible outside the anus. If there is no bleeding or the anus is not opened to see, most people still don't know that they have hemorrhoids. And when the stool is too hard, the "vascular ball" is punctured or scratched when the stool is relieved, it will bleed after the stool, and even "jet" outward. At this time, I hurriedly ran to the hospital. Upon examination, it was found that there was a "hemorrhoid", which is often referred to as "hemorrhoids in stage I" (bleeding, no lump hemorrhoids can be seen outside the anus).
We have to figure out two noun concepts: "hemorrhoids" and "hemorrhoids". From a professional point of view and the perspective of common people's understanding, these two terms are basically mixed in China, and there is no strict distinction, and "hemorrhoids" is more in line with the daily habits of ordinary people. However, strictly speaking, there is a difference. The original meaning of "hemorrhoids" is "protruding things", and the original meaning of "sores" is "cauliflower-like". Therefore, hemorrhoids are a serious stage of "hemorrhoids", that is, prominent cauliflower-like masses can be seen in the anus. Regardless of "hemorrhoids" and "hemorrhoids", there is only one word in English expression: Haemorrhoids. Its English meaning is "the sea of blood".
The formation of hemorrhoids is a manifestation of the body's "compensation" function, and it has an effect on people. But everything has a "degree", when it exceeds a certain "degree", problems will arise. In the process of hemorrhoid formation, when the cause is not removed, the effect continues, and the vicious circle is over. If the degree is too high, it will lead to "sickness". If you want to know "how serious hemorrhoids are," see the next section.
