Print DiagnosisDiagnosis for radiation enteritis might start with a discussion of your medical history and a physical exam. To see inside your small intestine, a long flexible tube with a camera is passed down your throat (endoscopy). Or the tube can be passed through your rectum to look at your large intestine (colonoscopy). Sometimes a pill-sized camera that you swallow is used to create pictures of your intestines (capsule endoscopy). Other tests might include imaging tests, such as X-rays, a CT scan or an MRI scan. Care at Mayo Clinic Our caring team of Mayo Clinic experts can help you with your radiation enteritis-related health concerns Start Here TreatmentRadiation enteritis treatment usually involves managing symptoms until they go away. This condition causes irritation of the intestines after radiation therapy for cancer. Your health care provider might recommend changes to your diet and medications for diarrhea and pain. Antibiotics can treat an overgrowth of bacteria. If radiation enteritis lasts longer, you might need a feeding tube. Sometimes, surgery is used to bypass the part of the intestine that's irritated.More InformationRadiation enteritis care at Mayo ClinicHome enteral nutrition By Mayo Clinic Staff Radiation enteritis care at Mayo Clinic Request an appointment Symptoms & causesDoctors & departments April 06, 2024 Print Living with radiation enteritis?
