Eosinophilic esophagitis
Clinical Classification Guidelines
Medical Intelligence & Overview
Eosinophilic Esophagitis (EoE) is a chronic inflammatory condition affecting the esophagus, the tube that carries food from the mouth to the stomach. Characterized by an accumulation of eosinophils—a type of white blood cell—in the esophageal lining, EoE can cause difficulty swallowing, food impaction, and discomfort. Recognized under ICD-10 code K20.0, this condition has become more frequently diagnosed and is considered an allergic inflammatory response often linked to food allergies or environmental allergens.
Causes & Symptoms
Clinical Causes: Food allergies: Certain foods such as dairy, nuts, soy, eggs, wheat, and seafood can trigger eosinophilic infiltration. Environmental allergens: Pollen, mold, and other airborne allergens may contribute to the condition. Genetic predisposition: A family history of allergic conditions suggests a genetic component. Immune system response: An abnormal immune response to allergens causes inflammation and eosinophil buildup. Other medical conditions: Some cases are associated with autoimmune diseases or gastroesophageal reflux disease (GERD).
Key Symptoms: Difficulty swallowing (dysphagia) Food impaction, where food gets stuck in the esophagus Chest pain or discomfort, especially behind the breastbone Food regurgitation or sensation of food sticking Persistent heartburn or acid reflux Nausea and sometimes vomiting Difficulty swallowing liquids or solids Failure to thrive in children (poor growth and weight gain)
Diagnostic & Treatment
Diagnosis Path: Diagnosing eosinophilic esophagitis involves a combination of medical history, symptom assessment, and specialized testing. A healthcare provider may recommend the following:
Treatment Protocols: Management of eosinophilic esophagitis targets reducing inflammation, avoiding triggers, and relieving symptoms. Common approaches include:
