###Human: I noticed bright red blood on the toilet paper and my anus was bleeding. What could it be? ###Assistant: Hello. You need to get your stool examined for the possibility of parasites which can cause such local irritation. Also, malabsorption of certain compounds in food can lead to local irritation after passing stools. Fresh bleeding is possible if the stools are hard, but there is no such history in your case. I will advise you the following medicines for a week, and if it still does not resolve, please get yourself examined by your physician. Consult your specialist doctor, discuss with him or her and start taking the medicines after their consent. Drink plenty of water and avoid spicy foods for a week. If the bleeding is persistent, please get yourself examined.
