Eosinophilic Esophagitis: The Allergic Condition That Feels Like GERD but Isn't

What Is Eosinophilic Esophagitis?

Eosinophilic esophagitis (EoE) is a chronic immune-mediated condition where white blood cells called eosinophils build up in the lining of the esophagus. This inflammation can make swallowing painful or difficult and may feel a lot like acid reflux (GERD), but it isn't the same thing.

Key points:

• Eosinophils are part of your immune system's response to allergens.
• In EoE, they collect in the esophagus, causing irritation.
• EoE can affect both children and adults.

How Eosinophilic Esophagitis Differs from GERD

It's easy to confuse EoE with gastroesophageal reflux disease (GERD) because both can cause:

• Heartburn
• Chest discomfort
• Difficulty swallowing

However, in GERD, stomach acid repeatedly backs up into the esophagus. In EoE, the problem is an allergic reaction that drives inflammation. Treating EoE with only acid-suppressing medications often doesn't fully resolve symptoms.

Common Symptoms of Eosinophilic Esophagitis

Symptoms can vary by age and severity. They often come on gradually and may include:

• In Adults

• Trouble swallowing (dysphagia)
• Food getting "stuck" in the throat (food impaction)
• Chest pain that isn't heart-related
• Persistent heartburn or reflux symptoms despite acid blockers

• In Children

• Poor appetite or feeding refusal
• Slow growth or weight loss
• Vomiting, nausea, or stomach pain
• Irritability during feeding

Because these signs overlap with other conditions, EoE is often underdiagnosed. If you or your child experience these issues, Ubie's free AI-powered Eosinophilic Esophagitis symptom checker can help you understand your symptoms in just a few minutes and guide your next steps.

What Causes Eosinophilic Esophagitis?

The exact cause isn't fully understood, but it appears to be linked to:

• Food Allergies: Common triggers include dairy, wheat, soy, eggs, nuts, and seafood.
• Environmental Allergens: Pollen, dust mites, molds, and animal dander.
• Genetic Factors: A family history of EoE, asthma, eczema, or other allergic conditions increases risk.

When these allergens enter the esophagus, they can trigger an immune response. Eosinophils rush in to fight off the perceived threat, causing inflammation and tissue remodeling over time.

Diagnosing Eosinophilic Esophagitis

Accurate diagnosis usually involves several steps:

1. Medical History and Physical Exam
   • Your doctor will ask about symptoms, allergy history, and response to acid-suppressing medications.
2. Endoscopy and Biopsy
   • A thin tube with a camera (endoscope) is inserted through the mouth to view the esophagus.
   • Small tissue samples (biopsies) are taken to count eosinophils under a microscope.
3. Allergy Testing
   • Skin prick tests or blood tests may identify specific food or environmental allergens.
4. pH Monitoring (Optional)
   • Measures acid levels in the esophagus over 24 hours to rule out GERD.

A diagnosis of EoE is confirmed when more than 15 eosinophils are found per high-power field in esophageal biopsy specimens.

Treatment Options

Managing eosinophilic esophagitis typically involves a combination of dietary changes, medications, and, in some cases, procedures. The goal is to reduce inflammation, prevent complications, and improve quality of life.

1. Dietary Therapy

Elimination diets help identify and remove trigger foods:

• Six-Food Elimination Diet (SFED): Remove dairy, wheat, soy, eggs, nuts, and seafood, then reintroduce one at a time.
• Targeted Elimination: Remove only the foods identified by allergy testing.
• Elemental Diet: Replace all meals with an amino acid–based formula. This is very effective but can be challenging to follow.

A nutritionist or dietitian can guide you through safe reintroduction and ensure you're still getting enough calories and nutrients.

2. Medications

Medications aim to reduce inflammation in the esophagus:

• Topical Steroids: Swallowed fluticasone or budesonide can calm inflammation.
• Proton Pump Inhibitors (PPIs): Though designed for acid reflux, PPIs may also have anti-inflammatory effects in EoE.
• Biologics: Newer injectable medications targeting specific immune pathways are under study and may be an option in severe cases.

Always follow your doctor's instructions on dosage and duration.

3. Esophageal Dilation

If narrowing (strictures) of the esophagus develops, dilation can stretch the narrowed area:

• Performed during endoscopy.
• Provides quick relief of swallowing difficulties.
• May need to be repeated periodically.

Dilation doesn't treat the underlying inflammation, so it's used in combination with dietary and medical therapies.

Living Well with Eosinophilic Esophagitis

While EoE is a chronic condition, many people achieve good control with the right plan. Here are practical tips:

• Keep a symptom diary.
• Track foods you eat and any reactions.
• Work with an allergist and gastroenterologist.
• Maintain balanced nutrition, especially if on an elimination diet.
• Learn stress-management techniques (e.g., breathing exercises, yoga).
• Stay up to date on follow-up endoscopies and biopsies as recommended.

Regular monitoring helps catch changes early and adjust treatments as needed.

When to Seek Medical Help

EoE can lead to serious complications if untreated:

• Food impactions requiring emergency removal
• Esophageal tears or perforations
• Significant weight loss or malnutrition

Speak to a doctor right away if you or someone you care for experiences:

• Inability to swallow liquids or saliva
• Severe chest pain or unrelenting vomiting
• Signs of dehydration or rapid weight loss
