Itchy anus, blood in stool when wiping stool, do not be nervous when this occurs.1. More common are mixed hemorrhoids. The hemorrhoids are varicose venous masses that generally increase in abdominal pressure, constipation or diet of spicy and stimulating foods, which can lead to pathological hypertrophy and displacement of the anal cushion, thus leading to increased pressure in the hemorrhoidal veins and blood in the feces when wiping the stool. Sometimes mixed hemorrhoids can cause mucus and feces to stain the skin around the anus, which can cause anal itching. This is a very good way to get the most out of your life. 2. The possible causes of anal itching with blood in the stool are anal fissures, such as long-term dry stools, which can cause skin cracks around the anus and lead to anal fissures, which can lead to blood in the stool when wiping, and sometimes pain in the anus. 3. Perianal eczema, a fungal infection that causes radioactive fissures in the perianal skin, some local oozing, and if the fissures are deep, blood in the stool can also occur. So there are many reasons for anal itching with blood in the stool, which should be treated symptomatically.
