Eosinophilic Esophagitis (EoE) is a common condition in children, occuring more frequently in boys than in girls. It is usually associated with any of the following symptoms:

• Nausea
• Problems swallowing (dysphagia)
• Vomiting
• Stomach pain
• Chest pain
• Heartburn
• Food impaction

Such symptoms are not very specific and often not easy to interpret. Thus, the diagnosis of EoE is rarely, if ever, may be done without an endoscopic exam. 

A pediatric allergist must be closely involved with treatment, which is usually focused on dietary eliminations and/or a topical steroid therapy.
