Fistulas
Interestingly enough, fistulas are pockets or passageways connecting two organs. However, these passageways should not exist, and the organs should not have access to each other through a fistula. Such an abnormal pocket or opening, especially around the anus, can cause a discharge of pus or blood, resulting in anal bleeding. Typically, a fistula occurs due to abscesses, where a pocket appears and fills with pus due to an infection. When the abscess is large enough, it could potentially cause an opening between two organs, depending on the location. As far as the treatment goes, doctors usually treat a fistula diagnosis with a round of antibiotics.
With the help of antibiotics, the body can usually handle the fistula on its own, healing and filling the pocket. However, there are some situations where the fistula becomes a more severe issue, requiring surgery if the opening progresses and becomes more prominent. Fistulas are more of an extreme case than diverticula, so it’s crucial to speak to the doctor when you notice a discharge of pus alongside blood during anal bleeding.
