Eosinophilic Esophagitis (EoE): What You Need to Know About This Condition

Eosinophilic Esophagitis (EoE) is a long-term condition that affects your esophagus—the tube that carries food from your mouth to your stomach. It happens when a large number of white blood cells called eosinophils build up in the lining of the esophagus. This bildup usually happens because of a reaction to certain foods or environmental allergens like pollen.When the esophagus becomes inflamed, it can lead to problems like trouble swallowing or food getting stuck in your throat. Over time, this can cause damage to the esophagus.Although EoE was once considered rare, doctors are diagnosing it more often now, especially in children and young adults.

How Eosinophilic Esophagitis (EoE) Works

In EoE, your immune system overreacts to allergens and sends too many eosinophils to your esophagus. Often, these cells cause swelling and irritation. As a result, swallowing becomes harder and sometimes painful.

Many people with EoE also have other allergic conditions like asthma, eczema, or seasonal allergies.

Types of EoE

Doctors don’t have official types of EoE. However, they often describe it based on how severe the symptoms are and how many eosinophils (a type of white blood cell) are found in the esophagus. Often, EoE appears along with other allergic conditions like asthma, eczema, or seasonal allergies.

How Common is EoE?

Eosinophilic Esophagitis (EoE) is relatively rare but has been increasing in prevalence over the past decade, especially in children and young adults. However, it is more common in males than females and often presents in individuals who have other allergic conditions.

Common Symptoms

  • Trouble swallowing
  • Food getting stuck in the throat
  • Chest pain or a burning feeling (like heartburn)
  • Sore or irritated throat
  • Nausea or vomiting
  • Poor growth or weight loss in children due to eating problems

Common Causes

  • Food Allergies: Common foods that may trigger EoE include dairy, wheat, eggs, soy, nuts, and seafood.
  • Environmental Allergens: Things like pollen or dust can also be triggers.
  • Immune Response: EoE is an immune system reaction, not an infection.
  • Family History: If someone in your family has EoE or allergies, your risk may be higher.

FAQs

If you have EoE, certain foods may trigger your symptoms. The most common triggers include dairy, wheat, soy, eggs, nuts, and seafood. To find out which foods are causing problems, doctors often suggest an elimination diet or allergy testing. These methods can help you know which foods to avoid to feel better.

Doctors diagnose EoE by doing an upper endoscopy. During this procedure, they use a thin tube with a camera to look inside your esophagus. They also take small tissue samples (biopsies) to check for high numbers of eosinophils, which are a type of white blood cell. In addition, doctors may do allergy testing to help find possible triggers.

There is no cure for EoE, but you can manage it with the right treatment. Most people find relief by changing their diet, taking medications like corticosteroids, and avoiding known allergens. With proper care, symptoms can be controlled.

Doctors use several ways to treat EoE:

  • Diet changes to remove trigger foods
  • Swallowed corticosteroids to reduce swelling in the esophagus
  • Proton pump inhibitors (PPIs) to reduce acid and help healing
  • Esophageal dilation (in serious cases) to widen a narrow esophagus caused by scarring

Each treatment is chosen based on your symptoms and how severe the condition is.

Yes, EoE is often seen in people who have other allergic conditions like asthma, eczema, or seasonal allergies. These problems may share the same immune system response, which can explain why they happen together.

EoE can cause different symptoms depending on your age:

  • Common symptoms include stomach pain, food getting stuck in your throat, nausea, and regurgitation (when food comes back up).
  • In babies or toddlers, signs may include vomiting, refusing to eat, or not gaining enough weight.

In older children and adults, common symptoms are trouble swallowing (dysphagia), heartburn, or chest pain.

Not exactly. While certain foods often trigger EoE, it is not the same as a typical food allergy. EoE is a chronic immune condition where eosinophils build up in the esophagus, causing inflammation. Avoiding trigger foods can help, but EoE needs special treatment beyond just allergy care.
