In addition to the anal sphincter, which is the main “coarse control switch”, the anal cushion (the “spongy body” formed by the venous plexus in the anal canal) is also needed to close the anal canal tightly and without leakage. “), a “fine adjustment switch”. The pressure inside the anus is regulated by the “amount of blood” in the venous plexus inside the anal cushion, which is fast and fine and ensures that the “asshole” does not run out of air and water. However, when the following three aspects become obstructed: 1) pressure overload in the rectum; 2) decrease in the strength of the anal sphincter; 3) disturbance of the neuroregulatory reflex system in the anal area. In time, the “vascular plexus” of the anal cushion will compensate for the expansion of hypertrophy and bulge into a “grape ball” shape, which is called “hemorrhoids” at this time. When the anal cushion begins to form a grape-like “hemorrhoid”, it is not visible outside the anus, and most people don’t know they have a “hemorrhoid” if they don’t bleed or hold the anus open to see it. When the stool is too hard and the “blood vessel ball” is punctured or bruised when you relieve the stool, it will bleed after the stool and even “spray” towards the outside. This is the time to rush to the hospital and find out that you have “hemorrhoids”, which are often called “stage I internal hemorrhoids” (bleeding, no mass of hemorrhoids can be seen outside the anus). We need to be clear about two terminology concepts: “hemorrhoids” and “piles”. From a professional point of view and from the point of view of the common people, these two terms are basically mixed in our country, without a strict distinction, while “hemorrhoids” is more in line with the daily habits of the common people. However, strictly speaking, there is a difference, as “hemorrhoid” originally means “something raised” and “sore” originally means “cauliflower-like The original meaning of “hemorrhoid” is “a raised object” and “sore” is “cauliflower-like. Therefore, hemorrhoids are the severe stage of “hemorrhoids”, which are protruding cauliflower-like masses that can be seen in the anus. Both “hemorrhoids” and “hemorrhoids” are expressed in English in one word: Haemorrhoids, which means “sea of blood”. The formation of hemorrhoids is a reflection of the body’s “compensatory” function, which is useful for people. But everything has a “degree”, and when it exceeds a certain “degree”, there will be problems. The process of hemorrhoid formation, when the cause is not lifted, the continuous effect, vicious circle, too “degree” will lead to “disease”.
