Eosinophilic Esophagitis (EoE) and Heartburn

What is eosinophilic esophagitis? EoE is a chronic immune-driven inflammation of the esophagus in which immune cells called eosinophils build up in the esophageal lining, often in response to foods. It mimics heartburn but does not respond well to acid suppression alone, and its hallmark signs are difficulty swallowing solids and food getting stuck. In our Wilmington practice we test for the food and gut drivers behind it and coordinate with your gastroenterologist.

What EoE is

Eosinophilic esophagitis is an allergic and inflammatory condition of the esophagus. The immune system reacts to something reaching the esophageal lining, most often food proteins, and sends eosinophils, a type of white blood cell, into the tissue. Over time that chronic inflammation makes the esophagus stiffer and its opening narrower.

EoE used to be considered rare. It is now recognized far more often, in both adults and children. The important point for anyone with stubborn reflux: it behaves like GERD on the surface, but the engine driving it is immune inflammation rather than acid alone.

How EoE causes heartburn and swallowing trouble

The inflamed esophagus produces exactly the symptoms people attribute to reflux: burning behind the breastbone, chest discomfort after meals, and regurgitation. But the same inflammation also impairs the esophagus's ability to stretch and push food down. That is why swallowing problems are the distinguishing feature. Food slows, sticks, or feels like it lodges midway down.

Because acid suppression soothes irritation but does not switch off the immune reaction, many people with EoE take reflux medication for years with only partial relief. When heartburn shrugs off a properly dosed PPI, EoE belongs on the list of things to evaluate rather than simply escalating acid blockade.

Signs and symptoms

• Difficulty swallowing solids, especially bread, meat, or dry foods
• Food feeling stuck or passing slowly on the way down
• Heartburn or chest burning that persists despite medication
• Chest pain during or after meals, with the heart ruled out
• Regurgitation of undigested food
• Meals that drag on because each bite takes effort
• Unintentional food avoidance or preference for liquids and soft foods
• In children: feeding refusal, slow eating, food aversion, or poor weight gain
• Episodes where swallowing stops completely (a medical emergency)

Root causes and triggers we look for

EoE is immune-driven, so our attention goes to what the immune system is reacting to and why the gut barrier is letting it through:

• Food immune reactions — the most common drivers. Dairy, wheat, eggs, and soy are frequent offenders, but each person is different. See food sensitivities causing reflux.
• Gut microbiome imbalances — dysbiosis and bacterial overgrowth that increase immune reactivity and inflammation.
• Intestinal permeability — a disrupted gut lining that exposes the immune system to more food fragments than it should see.
• Environmental allergies — seasonal or airborne allergies that can contribute alongside foods.
• Coexisting reflux — genuine GERD can sit alongside EoE, as described on our GERD page.

How EoE is tested and how we support the search

Being straight with you: EoE is diagnosed by a gastroenterologist through an endoscopy with biopsies that count eosinophils in the esophageal tissue. No lab kit replaces that. What functional testing does is find the drivers behind the immune response, which is exactly where our work fits.

• Alletess 184 Food Sensitivity Panel — immune response (IgG/IgE) to 184 common foods to identify candidate trigger foods for a structured elimination. This is not a standard allergy test and does not replace allergy evaluation.
• Comprehensive Stool Analysis — microbiome analysis covering bacterial overgrowth, H. pylori, parasites, and digestive markers such as elastase and inflammation. See stool testing.
• Adrenocortex Stress Profile / HU-Map — cortisol rhythms that influence immune regulation and gut barrier repair.

We also support the dietary strategy that gastroenterologists use in EoE, whether that is a targeted elimination based on your panel or a broader elimination diet, with careful reintroduction so nutrition does not suffer.

EoE vs typical reflux

Feature	EoE	Typical GERD
Main engine	Immune inflammation with eosinophils	Acid refluxing past a weak valve
Swallowing	Often difficult; food sticks	Usually normal unless severe
Response to acid suppression	Partial at best	Usually noticeable relief
Food link	Immune reactions to specific foods	Triggers that relax the valve or add pressure
Confirmed by	Endoscopy with biopsy	Symptom pattern, monitoring, sometimes endoscopy

How we address EoE

Our care plan runs alongside your medical care, never instead of it. Using your test results, we typically build a structured food elimination and reintroduction plan, support the gut lining and barrier function, rebalance the microbiome where testing shows overgrowth, and address stress hormone rhythms that affect immune regulation and healing. The goal is fewer flares, easier swallowing, and a diet you can actually live with.

We do not prescribe. If you are on medication for EoE or reflux, we build any gradual step-down plan with your prescribing doctor, and we welcome coordination with your gastroenterologist. Retesting and symptom tracking tell us what is actually working rather than what we hoped would.

When to seek urgent care

Food impaction is an emergency: if food becomes completely stuck and you cannot swallow your own saliva, go to the ER immediately. Seek prompt care for painful swallowing that keeps you from eating or drinking, chest pain with the heart ruled out, vomiting that will not stop, or rapid weight loss. Chest pain with shortness of breath, sweating, or arm or jaw pain always requires emergency evaluation first.
