Proctitis
Causes of Proctitis
Proctitis has several causes. It may result from Crohn Disease or —see Clostridioides (formerly Clostridium) difficile–Induced Colitis ). A person whose immune system is impaired is also at increased risk of developing proctitis, particularly from infections by herpes simplex virus or cytomegalovirus. Another cause of proctitis is radiation therapy directed at or near the rectum, which is commonly used to treat prostate and rectal cancer.
