Gastritis eosinophilic

Almost all patients with eosinophilic gastroenteritis have a peripheral eosinophilia. A history of allergy can be obtained in half of the patients. The stomach can be solely involved, but more commonly the small bowel also participates in the disease process. If patients only have eosinophilic gastritis, they present with epigastric pain, nausea and vomiting or hematemesis and/or melena, while patients with eosinophilic enteritis will have diarrhea, malabsorption or a protein-losing enteropathy.
