EGE presents with nonspecific symptomatology and is a difficult diagnosis to distinguish from other causes of GI inflammation or malabsorption. The symptom profile varies depending on the depth of eosinophil infiltration:
- Mucosal disease (most common) – Abdominal pain, nausea, diarrhea, vomiting. Malabsorption with micronutrient deficiency, anemia, and protein-losing enteropathy.
- Muscular layer infiltration – Bowel obstruction due to intestinal wall thickening.
- Subserosal disease (least common) – Ascites not explained by another mechanism and symptoms of mucosal and muscular layer disease.
