Anal disease is a common human disease, multi-morbidity, there are “ten people nine hemorrhoids” said, but because the site is special, most people avoid the disease, when the anus issued a danger signal, negligence, most often thought that the hemorrhoids committed, do not know in the hemorrhoids under the cover, there are many diseases, if you abuse drug treatment, delayed diagnosis and treatment on It’s too late to regret. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. Intermittent painless stools with fresh blood is a typical feature of hemorrhoids with blood in the stool, but it may also be caused by rectal polyps. Rectal polyps are often the precursor to rectal cancer and should be removed as soon as they are discovered. It is also important to be aware of other conditions that may be more dangerous, and should not be mistaken for hemorrhoids. If the blood in the stool is accompanied by severe pain, which is slightly relieved after the stool but intensifies, and can last for several hours, this may be a fissure in the anus, which can affect normal life in severe cases. If you have persistent or repeated episodes of diarrhea, mucus and blood stool, blood color is not fresh, accompanied by abdominal pain or fever, emaciation, weakness and other systemic symptoms, you may have ulcerative colitis, which can lead to severe malnutrition over time. If the stool with fresh blood or dark red blood, and accompanied by changes in the shape of the stool, thin or grooved stool, or with frequent bowel movements, several times a day to dozens of times, but each stool volume is very small or only a small amount of blood and mucus, that may be rectal cancer, if you still think that the hemorrhoids committed that would be a big mistake. 2.Pain anal pain is various, as if it is not as terrible as bleeding, but it also kills when it hurts. One condition is the anal fissure mentioned earlier, the pain has a cyclical character, pain during the stool, slightly relieved after the stool, and then intensified, mostly due to dry stool, in turn, because the pain does not dare to defecate, so that the dry stool aggravates, forming a vicious circle. Another condition may be caused by thrombosed or inflammatory external or internal hemorrhoids that have prolapsed and cannot be returned, unlike anal fissures, which are sudden, painful, persistent, distending or stabbing, and accompanied by a raised lump at the anal verge. The last condition that is most likely to be misdiagnosed is perianal abscess, superficially accompanied by redness and swelling at the anal verge, sometimes mistaken for a fire boil or hemorrhoid, which may break down and flow pus after a few days, often forming an anal fistula that does not heal for a long time. Deep perianal abscesses are not obvious in pain or only have swelling discomfort, often accompanied by different degrees of fever, sometimes thinking that it is a cold, abuse cold medicine treatment, the result is to delay the disease, and even cause sepsis, increasing the difficulty of treatment. 3, flowing pus or pus blood if the anal part when flowing pus or pus blood, can be noted, you may have an anal fistula, some anal fistula is not obvious abscess stage, that is, no obvious pain. Sometimes small boils can be palpable around the anus, repeatedly breaking out of the head, is not good, this can not be careless, if it is a fistula, repeated episodes of fistula will become more and more complex and increase the difficulty of treatment, so that the surgical trauma increased, the post-operative recovery time is extended. 4 perianal itching the above anal disease repeatedly, after a long time, the skin around the anus is often impregnated by various secretions, may cause perianal eczema, itching, such as the cause of the disease is not removed, it is difficult to cure. If the itching around the anus is mainly at night, then we can’t except if you have pinworm disease, pinworm is a kind of intestinal parasite, white thread-like, the longest not more than 1, 5 cm, female worms crawl out of the anus at night to lay eggs, causing strange itching. In short, if the anus sends out danger signals, it means that the body has gone wrong, you must pay attention to it, sometimes you do have hemorrhoids before, but other diseases can often develop secretly under the cover of hemorrhoids, so it is best to go to a specialist hospital for a comprehensive examination, do not miss the disease, so as not to cause serious consequences, bringing you lifelong regrets.
