Radiation Colitis

Radiation colitis
Specialty	Gastroenterology
Causes	Radiation therapy

Radiation colitis is injury to the colon caused by radiation therapy.^[1] It is usually associated with treatment for prostate cancer or cervical cancer.^[1] Common symptoms are diarrhea, a feeling of being unable to empty the bowel,^[2] gastrointestinal bleeding, and abdominal pain.^[1]

If symptoms of radiation colitis onset within 60 days of exposure to radiation, it is referred to as acute; otherwise, it is classified as chronic.^[1] Acute radiation colitis may onset within a few hours of radiation exposure, and may clear up within two or three months after radiation ends.^[1] Between 5 and 15% of individuals who receive radiation to the pelvis may have chronic radiation colitis.^[1] Radiation therapy can also affect the bowel at the small intestine (radiation enteritis) or the rectum (radiation proctitis).^[2]
