Jensen et al. JPGN 2016; 62: 36-42.  The researchers used a large database (>75 million individuals) representative of US commercially-insured population to provide estimates of the prevalence of several eosinophilic disorders:

• Eosinophilic gastritis 6.3 per 100,000
• Eosinophilic gastroenteritis 8.4 per 100,000
• Eosinophilic colitis 3.3 per 100,000

In the associated commentary by Furuta et al (pg 1), clinicians are encouraged to urge patients with EGID to register on the Consortium for Eosinophilic Gastrointestinal Disease Research registry: https://www.rarediseasesnetwork.org/cms/CEGIR
