Thank you for the query.
Generally there should be no visible amount of blood in the stool. Fresh bright red blood on the toilet paper or on the surface of the stool is in most cases caused by hemorrhoids. Itching of the rectum
can be also present.
To get rid of it you should avoid constipations (increase fiber rich products and mineral water intake), increase physical activity and use hemorrhoids suppositories. Sitz baths with Quercus Cortex
can be helpful as well. If your symptoms wont go away in a week, you should have colonoscopy
performed to rule out any other reasons.
Hope this will help.
