Eosinophilic esophagitis (EoE) is characterized by a large number of white blood cells called eosinophils that cause inflammation in the esophagus (the tube that connects the mouth and stomach). Symptoms include:

​

• Dysphagia (difficulty swallowing)

• Food impactions (food gets stuck in esophagus)

• Nausea and vomiting

• Failure to thrive (poor growth, malnutrition or weight loss)

• Abdominal or chest pain

• Feeding refusal/intolerance or poor appetite
