Eosinophilic gastritis is a rare condition characterized by an excessive number of eosinophils, a type of white blood cell, in the stomach lining.

This leads to inflammation and can cause symptoms like abdominal pain, nausea, vomiting, and sometimes gastrointestinal bleeding.

The exact cause is often unclear, but it may be associated with allergies or other immune system disorders.

Treatment usually involves medications to reduce inflammation and manage symptoms and addressing any underlying conditions if identified.
