Eosinophilic Esophagitis (EoE)

Eosinophilic esophagitis (EoE) is a chronic immune-mediated disease where white blood cells called eosinophils build up in the esophagus, causing inflammation, scarring, and difficulty swallowing. New biologic treatment (Dupixent) has transformed outcomes for moderate-to-severe disease.

EoE affects approximately 160,000 Americans — rates have tripled in the last 20 years. Average diagnostic delay is 3–4 years from first symptom to diagnosis. It is NOT the same as acid reflux.

🔄 Myth vs. Fact
❌ Myth

"EoE is just bad acid reflux (GERD)."

👆 Tap to see the truth

✅ Fact

EoE and GERD feel similar but are completely different diseases. EoE is immune-mediated (not acid-driven) and requires different treatment. Antacids do not treat EoE.

❌ Myth

"If you can swallow, you don't have EoE."

👆 Tap to see the truth

✅ Fact

EoE can be present without obvious swallowing difficulty. Many patients adapt to slow eating and food textures so gradually they don't realize they have a problem.

👆 Tap to flip back

❌ Myth

"EoE only affects children."

👆 Tap to see the truth

✅ Fact

EoE is increasingly diagnosed in adults. The average adult with EoE has had symptoms for 7 years before diagnosis — often chalked up to reflux or anxiety.

👆 Tap to flip back

❌ Myth

"EoE is cured by eliminating foods."

👆 Tap to see the truth

✅ Fact

Elimination diets reduce symptoms and eosinophil counts but don't 'cure' EoE. Most patients require ongoing therapy — either dietary, topical steroids, or a biologic like Dupixent.

Did You Know?
EoE diagnoses have increased 500% over the past 20 years — paralleling rises in food allergies, asthma, and eczema.
The 'six-food elimination diet' (milk, wheat, egg, soy, nuts, seafood) achieves remission in ~70% of EoE patients.
Dupixent (dupilumab) is the first FDA-approved biologic for EoE and works by blocking IL-4/IL-13 signaling — the same pathway that drives eczema and asthma.
EoE is strongly associated with other atopic diseases: 70% of EoE patients also have asthma, eczema, or food allergies.
Food impaction — food getting stuck in the esophagus requiring emergency endoscopy — affects 1 in 3 EoE patients each year.
🍩 Breakdown by Type
70% Atopic
65% Male patients
70% Atopic comorbidity
45% Pediatric-onset
📅 Disease Progression
Years 1–3
Early Symptoms
Heartburn, regurgitation, intermittent dysphagia. Usually treated as GERD. Multiple PPI trials without resolution.
Years 3–7
Misdiagnosis Period
Symptoms persist. GI specialists often needed. Behavioral adaptation (eating slowly, avoiding certain textures) masks severity.
Year 5–10 avg
Endoscopy + Diagnosis
Upper endoscopy reveals classic EoE features (rings, furrows, plaques). Biopsy confirms ≥15 eos/hpf. Specialist referral critical.
3–12 months on therapy
Treatment Response
Dupixent or topical budesonide typically reduces eosinophil count within 12 weeks. Dietary therapy takes longer. Maintenance ongoing.

"EoE affects 160,000 Americans — and most wait 7+ years for a diagnosis while being treated for acid reflux."

💊 FDA-Approved Treatments for EoE

There are currently 2 FDA-approved disease-modifying therapies for EoE. These are targeted treatments — not just symptom management.

FDA Approved 2022

Dupixent

dupilumab

Company Regeneron / Sanofi
Drug type Biologic Injection
Approved for EoE in adults and children 1 year and older
List price ~$38,000–$50,000/year

💚 Financial Assistance Available

Dupixent MyWay assistance program brings costs to $0/month for eligible commercially insured patients. Free drug available for uninsured patients who qualify.

FDA Approved 2024

Eohilia

budesonide oral suspension

Company Takeda
Drug type Topical Corticosteroid
Approved for EoE in adults and children 11 years and older
List price ~$15,000–$20,000/year

💚 Financial Assistance Available

Takeda patient assistance programs available. Oral budesonide is swallowed (not spit) to coat the esophagus — cheaper than Dupixent with good efficacy for many patients.

⚠️ High-cost drugs: insurance navigation matters

These treatments require prior authorization from your insurer. Most commercial insurance plans cover them with co-pay assistance programs. Medicare and Medicaid coverage varies by state and therapy. Ask your specialist's office for a patient navigator or specialty pharmacy partner — they handle PA processes daily.

⏱️ Average diagnostic delay: 4+ years — don't wait for things to get worse

Just diagnosed with EoE? Here's what actually matters.

A diagnosis can feel overwhelming. Here's what patients and specialists say makes the biggest difference in the weeks after diagnosis.

🏥
1

Get to a GI specialist — or ideally an EoE expert

Not all gastroenterologists are EoE specialists. Look for a GI doctor who sees a significant EoE patient volume. Academic medical centers often have dedicated EoE programs.

🍽️
2

Understand your treatment options before choosing one

You'll likely be offered a choice between dietary therapy (elimination diet), topical steroids (Eohilia), or Dupixent (a biologic injection). Each has tradeoffs. Dietary therapy takes longer but avoids medication. Dupixent is convenient but expensive and requires injections. Discuss your lifestyle with your doctor.

🧪
3

Ask about repeat endoscopy to confirm response

After 8–12 weeks of treatment, your doctor should perform a follow-up endoscopy to check if eosinophil counts have dropped. If your first treatment isn't working, switching or combining treatments is common.

💊
4

Ask about patient assistance if cost is a concern

Dupixent (biologic) has a patient assistance program (Dupixent MyWay) that can bring co-pays to $0 for commercially insured patients. Eohilia has similar support. Don't let cost stop you from accessing proven treatment.

📱
5

Connect with the EoE community

The American Partnership for Eosinophilic Disorders (APFED) at apfed.org has patient guides, webinars, and a patient community. Many newly diagnosed patients find immense value in connecting with others who've navigated food trials and treatment decisions.
