Definition of Radiation enteritis
Radiation is damage to the lining of the intestines (bowels) due to radiation therapy, a type of cancer treatment.
Causes, incidence, and risk factors
Radiation therapy uses high-powered x-rays, particles, or radioactive seeds to kill cancer cells.
Symptoms
Symptoms may be different depending on what part of the intestines received the radiation.
Signs and tests
The health care provider will do a physical exam and ask you questions about your medical history.
Treatment
Starting a low-fiber diet on the first day of radiation treatment can be helpful.
Expectations (prognosis)
When the abdomen receives radiation, there is always some nausea, vomiting, and diarrhea. In most cases, the symptoms get better 2 – 3 weeks after treatment ends.
