Diagnosis

Diagnosis for radiation enteritis might start with a discussion of your medical history and a physical exam. This condition causes irritation of the intestines after radiation therapy for cancer. To see inside your small intestine, your doctor might pass a long flexible tube with a camera down your throat. Or the tube can be passed through your rectum to look at your large intestine. Sometimes doctors use a pill-sized camera that you swallow to create pictures of your intestines. Other tests might include imaging tests like CT and MRI.

Treatment

Radiation enteritis treatment usually involves things to make you feel better until it goes away. This condition causes irritation of the intestines after radiation therapy for cancer. Your doctor might recommend changes to your diet and medicines for diarrhea and pain. If your radiation enteritis lasts longer, you might need a feeding tube. Antibiotics can treat an overgrowth of bacteria. Sometimes surgery is used to bypass the part of your intestine that's irritated.
