There is a disease in the world that many people suffer from, “it” has a very high incidence and can be painful; “it” can easily lead to a variety of diseases, such as causing anemia, and can even mask the symptoms of rectal cancer; “it “is an unspeakable problem, so many people, especially women, would rather endure it than go to the hospital. Who is this it? It is hemorrhoids. Human body structure that causes humans to be prone to hemorrhoids Hemorrhoids are a disease unique to humans, and there is no such disease in the animal kingdom. Many years ago, our human ancestors chose to walk upright, so that the upper limbs can be liberated, greatly expanding the brain capacity, but the side effect is that, because humans walk upright, the rectal veins have not evolved to keep up, and no venous valve is formed; unlike the veins of the limbs have a venous valve, the venous valve closes when the blood flows back, which can reduce blood reflux; and the rectal veins do not have this venous valve, the blood flows back by gravity The blood reflux is influenced by gravity, which causes the blood to stagnate, causing the veins to dilate and form varicose veins. This results in the formation of hemorrhoids. Animals, on the other hand, are on all fours and do not get hemorrhoids because they are under less gravitational pressure. There are 3 categories of hemorrhoids depending on the site of occurrence The anus is a very delicate, nerve-rich, special organ. And hemorrhoids, depending on the site of occurrence, are divided into internal, external, and mixed hemorrhoids. There is a jagged visible line called the dentate line where the skin of the anal canal meets the rectal mucosa. The varicose veins above the dentate line are internal hemorrhoids, and those below the dentate line are external hemorrhoids; those with both internal and external hemorrhoids are mixed hemorrhoids, where the internal hemorrhoids fuse with the corresponding external hemorrhoids through the venous plexus, i.e. the anastomosis of the upper and lower venous plexus. It is not a common belief that outside the anus is external hemorrhoids and inside the anus is internal hemorrhoids. Which of the three types of hemorrhoids is more dangerous? It is not simply which type of hemorrhoid is more dangerous. In fact, each type of hemorrhoid can be very serious when it reaches its final stage of development. For example, internal hemorrhoids, when bleeding is severe, can lead to hemorrhagic anemia, which can be serious enough to cause fainting and shock. I have seen cases of internal hemorrhoids bleeding leading to shock. External hemorrhoids that have thrombosis or inflammatory edema, mainly painful, should be seen promptly. Otherwise, the condition can worsen and cause tissue necrosis. Mixed hemorrhoids can also be extremely dangerous if not operated on in time, causing infection, necrosis, and even systemic infection and critical illness. Depending on the severity, hemorrhoids can be divided into the first stage, where blood is predominantly coming out, not prolapsing, and slightly bulging. In the second stage, the nucleus of the hemorrhoid is prolapsed, but can be returned on its own, the size of a peanut or walnut. The third stage, the prolapse can not be returned, need to be sent back by hand, hemorrhoids have a single nucleus prolapse, there are also ring prolapse, single nucleus is a hemorrhoid nucleus out; ring like this circle of small tomatoes, hemorrhoid nucleus around a circle, fall out. The fourth stage, mixed hemorrhoids embedded, hemorrhoids prolapse can not be returned, there is thrombosis and inflammatory edema, seriously affect life. How to distinguish hemorrhoids from bowel cancer? Because it is difficult to talk about it, many people who suffer from hemorrhoids will not go to the hospital for consultation. But it is this embarrassment that can very easily lead to serious consequences. I once had a patient who delayed coming for treatment for a long time because he was too ashamed to talk about it, and then surprisingly found out that he had advanced low-grade rectal cancer. Because of the early bleeding, it has been considered as hemorrhoid bleeding, which hides the symptoms of rectal cancer. If we can find out it is rectal cancer early and treat it timely, we can minimize the damage to our body. If it is hemorrhoids, the blood in the stool is bright red in color, mostly related to eating spicy food before, and there is no habitual change in stool (it used to be once a day now it is still once a day). If it is bowel cancer, blood in stool is dark red in color, and there is no previous diet with a lot of spicy and stimulating food; there will be changes in stool habits, more frequent, weight loss, diet reduction, poor sleep, etc. If you play with cell phone, computer, read newspaper, etc. during defecation, these will cause distraction of willpower and prevent you from focusing on defecation, which will prolong the defecation time. If you miss the best defecation time and the desire to defecate disappears, you will have the stool that is not discharged, and the water in the stool will be reabsorbed by the intestine when you defecate next time, which will make the stool dry and form constipation; moreover, if you defecate for a long time, the abdominal pressure will increase, the venous reflux will be obstructed, and the anus will be locally The local congestion and edema of the anus can easily cause varicose veins and the formation of hemorrhoids. So we advocate that the toilet defecation time should not exceed 5 minutes.
