====Acute radiation proctitis====
Symptoms occur in the first few weeks after therapy. These symptoms include [[diarrhea]] and the urgent need to [[Defecation|defecate]], often with inability to do so ([[tenesmus]]). Acute radiation proctitis usually resolves without treatment after several months, but symptoms may improve with [[butyric acid|butyrate]] [[enema]]s. This acute phase is due to direct damage of the lining ([[epithelium]]) of the colon. <ref>Babb RR. ''Radiation proctitis: a review.'' Am J Gastroenterol. 1996 Jul;91(7):1309-11. Review.

Symptoms may begin as early as several months after therapy but occasionally not until several years later. These symptoms include diarrhea, [[Hematochezia|rectal bleeding]], painful defecation, and intestinal blockage. Intestinal blockage is a result of [[Stenosis|narrowing]] of the rectum which blocks the flow of [[feces]]. Connections [[fistulae]] may also develop between the colon and other parts of the body such as the [[skin]] or [[urinary system]].
