are hemorrhoids dangerous,Itching outside the anus

    After receiving some patients with itching or eczema outside the anus, after inquiring about the general situation, they are often recommended to have a specialist examination of the anorectal department—digital anal examination and anoscopy. Many patients feel very puzzled: "I have no blood in my stool, and I don't have any lumps when I relieve my stool, and there is nothing uncomfortable inside the anus, but the skin outside the anus is itchy. Just look at the outside and check what is inside?" External skin itching is often caused by internal anal diseases.

    Excessive secretion of fluid in the anus, or poor anal closure function, causes the fluid to sneak out of the anus, irritate the skin, and cause itching, dampness and other symptoms. Common intra-anal diseases such as proctitis, anal sinusitis, etc., because the anatomical location is close to the anal opening, local inflammation will cause increased exudation in the intestinal cavity, and our anus has a strong ability to solidify stool and block fluid. The ability is poor. These fluids are in the intestinal cavity. Because the intestinal wall can adapt to this environment, there will be no obvious discomfort. However, our skin cannot tolerate the spill outside the anus, so patients will feel that the skin around the anus is wet and itchy. In addition, there is also a type of intra-anal diseases that can cause poor anal closure. Intestinal fluids are more likely to leak out and induce anal itching, such as common hemorrhoids. Our understanding of hemorrhoids is often limited to bleeding and mass prolapse caused by hemorrhoids. In fact, everyone has "hemorrhoids" in the anus, which can help the anus close under normal conditions. But if you want to really help the anus close, it must be of the right size and its own place. Just like our teeth, if they are uneven, it will cause the mouth to close tightly. Bad life and defecation habits will make the hemorrhoids congested and swollen or leave the normal position, then the closure of the anus will be affected, and the intestinal juice will not Staying behind in the anus, "going out to make chaos", secondary anal itching.

    Therefore, for the symptoms of skin itching outside the anus, it is necessary to carry out corresponding examinations for diseases inside the anus. If there is an intra-anal cause, then only "inside and out" treatment can achieve real results.
