Patients with dry and hard stools and bleeding are likely to have dry and hard stools that irritate the anal canal, leading to internal hemorrhoids and anal fissures. The main reason for dry and hard stools is constipation, which can lead to difficulties in defecation, and the long-term presence of stools in the rectum, where water is constantly reabsorbed, which in turn becomes increasingly dry and hard, stimulating the hemorrhoid area and anal canal when discharged from the anus, which may lead to the appearance of the two diseases mentioned above: internal hemorrhoids and anal fissures. If the patient has severe pain in the anus during defecation, it is possible that the fissure is caused by dry and hard stools. If there is no obvious pain during defecation, it is possible that the bleeding is caused by internal hemorrhoids due to dry and hard stools.
