The hemorrhoids are a common disease located in the anal area, and since ancient times in China there are “nine hemorrhoids in ten people”, because of its commonness and the specificity of the onset of the site, many people choose to withhold treatment in the early stages of the disease, and later on the hazards of hemorrhoids disrupt life and even threaten life. There are some vascular tissues near the anus, and straining during bowel movements can add a great burden to these vascular tissues, thus causing poor blood circulation and turning the blood-filled part of the tissue into a lumpy cyst, which forms a hemorrhoid. Medically speaking, hemorrhoids are divided into internal, external and mixed hemorrhoids. If a hemorrhoid grows inside the rectum, it is called an internal hemorrhoid, and if it grows near the anus, it is called an external hemorrhoid. Seventy-five percent of hemorrhoids are internal hemorrhoids, but generally speaking, internal hemorrhoids and external hemorrhoids occur in combination, which is called mixed hemorrhoids. If hemorrhoids are left untreated for a long time, it will aggravate the symptoms of blood in the stool, pain and itching, and in serious cases, it may cause the nucleus to prolapse and form an impaction, which may lead to necrosis and infection of other tissues, or cause perianal abscess and fistula, or even serious anal malfunction; the blood in the stool of hemorrhoids can cause iron deficiency anemia, and bacteria and toxins can invade the blood and cause septicemia; in addition, because the location of hemorrhoids and rectal cancer is similar, and they both have the same stool. In addition, because hemorrhoids and rectal cancer are similar in location and both have symptoms of blood in stool, rectal cancer is often misdiagnosed as hemorrhoids, and the existence of hemorrhoids can conceal rectal cancer and delay the best treatment time for rectal cancer, thus causing irreversible damage. Some people may think that the amount of blood lost in stool is small and will not cause anything to the total amount of blood in the body, but a drop of water can penetrate a stone, and blood in stool every day, 365 days a year, adds up to something that should not be underestimated. The blood in the stool of hemorrhoids can lead to a constant loss of iron in the body, making the body’s iron content lower than normal, causing iron deficiency anemia. Not only do you have to worry about the “outlet” every day, but you also have to face various symptoms of anemia, such as pallor, tiredness, palpitations, lack of energy, and memory loss. Another condition of hemorrhoids is the prolapse of internal hemorrhoids, and think about it, the prolapse of a cyst-like swelling at the anus, the daily movement will be very restricted, the mind will also be focused on that place, will cause emotional disorders, emotional depression and other mental injuries, the quality of life can not be talked about. The internal hemorrhoids that are prolapsed outside the anus are held by the sphincter muscle and the venous return is blocked, while the arterial blood is still constantly being input to increase the size of the internal hemorrhoids until the arterial blood vessels are pressed shut and the thrombus is formed, resulting in hardened hemorrhoids that are difficult to send back to the anus, thus causing unbearable pain. More seriously, the nucleus of the hemorrhoid, which is located outside the anus, is exposed to bacteria and other hazards to develop lesions, resulting in the accumulation of local metabolites and increased local edema in the anus, thus causing a vicious circle. The necrosis of the hemorrhoid nucleus may also cause infection of the local tissues, and in serious cases, sepsis. Both hemorrhoids and rectal cancer are diseases that develop at the end of the rectum, and both have the symptom of blood in the stool, so that when blood in the stool appears, people treat it as hemorrhoids, thus delaying the treatment of early rectal cancer and causing irreversible consequences. According to statistics, the misdiagnosis rate of rectal cancer being diagnosed as hemorrhoids is as high as 90%. When you think about the number of people suffering from rectal cancer, what a large number this would be and how many lives would be affected by the lack of attention to hemorrhoids. In short, hemorrhoids can cause a lot of harm to human health, and there are some hidden dangers that come with the symptoms of untreated hemorrhoids. Therefore, once you suffer from hemorrhoids, do not tolerate it because of the specificity of its location, but treat it properly and go to a regular hospital in time to find a doctor. At the same time, do not be overly nervous and fantasize about too many hazards, as long as they can be treated early and handled correctly, the above complications of various hazards are still relieved or even avoided.
