Eosinophilic (ee-uh-sin-uh-fil-ik) esophagitis (EoE) is an allergic condition that causes inflammation of the esophagus. The esophagus is the tube that sends food from the throat to the stomach. The most common symptom of EoE in adults is difficulty and sometimes pain in swallowing solid foods.

Research suggests that the leading cause of eosinophilic esophagitis is an allergy or a sensitivity to particular proteins found in foods. Many people with EoE have a family history of allergic disorders such as asthma, rhinitis, dermatitis or food allergy.

In order to diagnose EoE, a doctor will perform an endoscopy and a biopsy of the esophagus. This is usually done after medications to control acid reflux have failed to improve symptoms.

Diagnosing the condition is often a coordinated effort between a gastroenterologist and an allergist / immunologist. An allergist will determine the role that allergies may play in EE. Your allergist will perform allergy testing to diagnose which specific allergens may be involved with your EoE.
