Eosinophilic Esophagitis (EoE) is a chronic, immune-mediated disorder. EoE symptoms can overlap with symptoms of a condition called gastroesophageal reflux disease (GERD).

Patients with EoE experience symptoms described as:

• feeling like food or liquid is moving slowly
• feeling food or liquid going down
• food getting stuck in the esophagus
• acid reflux, chest pain, nausea, vomiting
• failure to thrive (children), regurgitation and esophageal strictures.

It occurs in approximately 1 in 10,000 people and affects people of all age groups, with males being affected more frequently. EOE is associated with food allergies or other allergens, causing eosinophils (type of white blood cell) to migrate from the bone marrow (via blood) and settle in the esophagus causing inflammation to the esophagus. No one knows exactly why EoE occurs.  People with EoE tend to have allergic conditions such asthma, seasonal allergies, allergic rhinitis, and eczema.
