The symptoms of radiation enteritis include diarrhea, nausea, vomiting and stomach cramps. Symptoms occur because of irritation of the intestines from radiation therapy for cancer. Symptoms usually go away several weeks after treatment ends. But sometimes they last longer. Radiation enteritis that goes on for longer can cause anemia and bowel obstruction. Risk factors The risk of radiation enteritis is higher in people undergoing radiation treatments for cancers in the belly and the pelvis. Radiation enteritis occurs because radiation therapy can cause irritation of the intestines.
