Medically reviewed by Min Clinic Staff | Updated: January 2026
Proctitis: Inflammation of the rectum. Proctitis may be due to a considerable number of causes, including infectious agents and ulcerative colitis. Infectious proctitis is often due to agents such as Chlamydia trachomatis, Neisseria gonorrheae, and herpes simplex virus, all of which can be acquired during anoreceptive intercourse. Proctitis is also a hallmark of ulcerative colitis, in which case it may be accompanied by intermittent rectal bleeding, crampy abdominal pain, and diarrhea.
