EoE - Eosinophilic Oesophagitis Overview Symptoms and causes Diagnosis Treatment What is EoE? Eosinophilic Oesophagitis (EoE) is the most common of the eosinophilic gut disorders occurring in approximately 1 in 2000 in the US, and 1 in 3000 in the UK. It is sometimes described as Oesophageal Asthma and is spelt ‘Eosinophilic Esophagitis’ in the US and Canada.

Having too many eosinophils, a type of white blood cell, in the oesophagus causes inflammation that makes swallowing difficult.
