Eosinophilic gastrointestinal disorder

Eosinophilic gastrointestinal disorder (EGID) is a disorder characterised by eosinophilic infiltration of the gastrointestinal tract. The most common form of EGID is Eosinophilic Esophagitis (EoE). Other forms of EGID include eosinophilic gastritis, eosinophilic enteritis, eosinophilic colitis and eosinophilic gastroenteritis (EGE). While these disorders are less frequent than EoE, their pathogenesis and treatment are probably similar. Clinically, patients with EGID often present with dysphagia, vomiting or abdominal pain. While the etiology remains unclear, there is a well documented association of atopy with EGID. Clinical studies in children and adults have demonstrated an association with food allergy.
