What is EoE?

EoE explained

Living with eosinophilic esophagitis (EoE) can be a confusing and unpredictable journey. EoE is a chronic inflammatory disease that occurs in the esophagus—the tube that passes food and liquid from the throat down to the stomach. The primary symptom of EoE is inflammation in the esophagus, which can lead to it narrowing and symptoms like:

  • Dysphagia (difficulty swallowing)
  • Food getting stuck
  • Chest pain
  • Swallowed food coming back up

What causes EoE?

EoE happens because the body’s immune system responds to certain allergens in the esophagus with a buildup of eosinophils (a type of white blood cell) and other inflammatory cells. This buildup creates the inflammation that causes EoE symptoms.

Damage from EoE

EoE inflammation may lead to physical damage to the esophagus, making symptoms worse.

Because of the nature of EoE, you may need to see certain specialists. These can include gastroenterologists, who specialize in treating conditions of the digestive system and can do tests, like an endoscopy, to diagnose EoE. You may need to see allergists and immunologists, who can test to see if you’re also allergic to certain foods and substances that may trigger your EoE.
