Radiation enteritis is often temporary. Your signs and symptoms may subside in the weeks after your treatment ends. During this time, your doctor may recommend treatments to relieve your signs and symptoms. If your radiation enteritis persists, your doctor may recommend other treatments.

Treatment for temporary radiation enteritis signs and symptoms

If you experience signs and symptoms of radiation enteritis, your doctor may recommend:

  • Anti-diarrheal medications
  • Dietary changes, such as reducing your intake of dairy products, fatty foods and high-fiber foods
  • Pain medications to relieve pain of inflammation

Treatment for chronic radiation enteritis

Radiation enteritis that persists after treatment or that develops months or years after treatment is called chronic radiation enteritis. Treatment for chronic radiation enteritis is similar to treatments used for temporary radiation enteritis, but may also include:

  • Nutritional support. Inflammation in your small intestine may reduce your body's ability to absorb nutrients from the foods you eat. Nutritional support in the form of tube feeding (home enteral nutrition) or infusions of nutrients into a vein (home parenteral nutrition) may help make sure you get the energy and nutrients you need.
  • Antibiotics. Inflammation caused by radiation may lead to a bacterial overgrowth in the small intestine. This can occur if the bacteria that normally live in the large intestine grow in the small intestine. Antibiotics can control bacteria overgrowth.
  • Surgery. In rare cases, your doctor may recommend surgery to remove the affected intestine or to construct a way for waste to avoid that section (intestinal bypass). Surgery is generally used when other alternatives are exhausted, since surgery carries a risk of complications.
