The symptoms of dry and granular stools with blood in the stool are mainly due to two reasons. First, dry and granular stool is a sign of constipation, mainly due to long-term improper diet and slow gastrointestinal peristalsis, resulting in indigestion. Secondly, bleeding stools are caused by constipation and trauma to the perianal tissues and the end of the rectum, the most common causes of bleeding are hemorrhoids and anal fissures. Dry stools can cause trauma to the anal mucosa and lead to mucosal congestion and eventually varicose veins, which can lead to hemorrhoid symptoms. At the same time, dry stool causes many fissures at the end of the rectum, and the bleeding stool caused by this condition is called anal fissure. You can apply hemorrhoid cream and erythromycin ointment to the affected area for timely treatment. Avoid eating cold, spicy and other stimulating foods.
