Eosinophilic Esophagitis vs GERD (Acid Reflux)
Clinical comparison — shared symptoms, key differences, distinguishing diagnostic tests, treatment pathways, and when to seek urgent evaluation.
Condition Overview
Condition A
Eosinophilic Esophagitis
Eosinophilic esophagitis is a chronic allergic inflammatory condition of the esophagus causing dysphagia, food impaction, and chest pain. It is managed with dietary elimination, proton pump inhibitors, or topical corticosteroids.
Condition B
GERD (Acid Reflux)
Gastroesophageal reflux disease (GERD) is a chronic condition where stomach acid flows back into the esophagus, causing heartburn, regurgitation, and chest discomfort. Long-term untreated GERD can lead to esophageal damage.
Shared Symptoms — Why They're Confused
Both conditions present with 3 overlapping symptoms, making clinical differentiation essential.
Key Clinical Differences
Eosinophilic Esophagitis
- Dysphagia (solid food), food impaction episodes
- Young atopic patient (eczema, asthma, allergies)
- Normal or ringed oesophagus on endoscopy
- Does not fully respond to PPI
GERD (Acid Reflux)
- Heartburn, regurgitation, acid-related symptoms
- Lower oesophageal symptoms predominate
- Responds well to PPI therapy
- Older or obese patients, hiatus hernia common
Distinguishing Diagnostic Tests
| Test | Eosinophilic Esophagitis | GERD (Acid Reflux) |
|---|---|---|
| PPI trial (8 weeks) | Partial or no response — EoE not PPI-responsive | Significant symptom relief — supports GERD |
| Endoscopy + oesophageal biopsy | Eosinophil count >15/hpf in mid/upper oesophagus — diagnostic | Normal biopsy or erosive oesophagitis; no eosinophilia |
| Oesophageal pH monitoring / manometry | Normal acid exposure; may have dysmotility | Abnormal acid exposure — confirms pathological GERD |
Treatment Approaches
Eosinophilic Esophagitis
- •Dietary elimination (6-food or targeted elimination diet)
- •Swallowed topical corticosteroids (fluticasone, budesonide)
- •Oesophageal dilatation for strictures
GERD (Acid Reflux)
- •High-dose PPI (omeprazole/lansoprazole)
- •Lifestyle modifications
- •Fundoplication for refractory cases
When Doctors Consider Each Diagnosis
🔵 Consider Eosinophilic Esophagitis when:
- →Young atopic patient, dysphagia, food impaction, PPI failure, eosinophils on biopsy
🟢 Consider GERD (Acid Reflux) when:
- →Heartburn, regurgitation, obese/hiatus hernia, good PPI response
