Eosinophilic Esophagitis

What is eosinophilic esophagitis?

Eosinophilic esophagitis (EoE) is a long-term (chronic) allergic and immune condition that happens in the esophagus. The esophagus is the tube that connects the back of your throat to your stomach. Food and liquid go down the tube when you swallow. Eosinophils are white blood cells found in the digestive tract. But they are not normally found in the esophagus. With EOE, your immune system reacts to allergens in the esophagus. It makes and multiplies eosinophils in the esophagus. This causes the esophagus to become inflamed. It can get narrowed and develop rings or pus-filled infections (abscesses). This can cause symptoms such as trouble swallowing.

What causes eosinophilic esophagitis?

EoE is caused by an allergic reaction to certain foods or other allergens in the environment.

Who is at risk for eosinophilic esophagitis?

EoE can happen at any age. It is most often seen in white men. You are more at risk if you have:

  • Atopic dermatitis

  • Asthma

  • Food allergies

  • Environmental allergies

  • Family history of EoE

Some other health conditions can cause eosinophils to increase in the esophagus. Your healthcare provider will need to test you for these conditions.

What are the symptoms of eosinophilic esophagitis?

Symptoms can occur a bit differently in each person. They can include:

  • Trouble swallowing

  • Chest pain or heartburn

  • Belly (abdominal) pain

  • Vomiting

  • Food getting stuck in the throat due to narrowing (a medical emergency)

  • Not enough growth or weight gain in children

The symptoms of eosinophilic esophagitis can seem like other health conditions. See your healthcare provider for a diagnosis.

How is eosinophilic esophagitis diagnosed?

You may see a healthcare provider called a gastroenterologist. He or she will ask about your symptoms and health history, and give you a physical exam. He or she may also ask about your family’s health history. You may also have tests, such as:

  • Allergy testing. This is a series of tests to see what substances you are allergic to.

  • Endoscopy. Your healthcare provider uses a tiny camera on a thin, flexible tube to look inside your esophagus for signs of irritation. He or she will likely need to take a small sample of tissue (biopsy) from your esophagus.

How is eosinophilic esophagitis treated?

You will work with an allergist or a gastroenterologist. No medicines can cure EoE. But some medicines can reduce the swelling in your esophagus. These include:

  • Corticosteroids

  • Proton pump inhibitors

Your healthcare provider will often try high-dose acid blockers for up to 8 weeks after diagnosis. He or she will then reassess you and your symptoms.

You can help manage EoE by learning what causes your allergic reaction, and staying away from those things. In many cases, the allergens come from food. Your healthcare provider will help you find out what substances or foods to stay away from. Unfortunately, allergy tests are not always helpful in this condition.

When starting a food elimination plan, it may take days or weeks to see which foods you are allergic to. This is because reactions related to EoE might take days or weeks to develop. You may need to not eat foods such as:

  • Dairy

  • Eggs

  • Wheat

  • Soy

  • Peanuts

  • Tree nuts such as almonds

  • Fish and shellfish

In some cases, the esophagus needs to be stretched (dilated) if it has narrowed.

Talk with your healthcare providers about the risks, benefits, and possible side effects of all treatments.

What are possible complications of eosinophilic esophagitis?

If left untreated, symptoms will continue. This can damage the esophagus can cause it to narrow. The long-term complications of EoE are not fully understood.

What can I do to prevent eosinophilic esophagitis?

Researchers don’t know how to prevent the condition. But managing your contact with allergens can help lessen symptoms.

Living with eosinophilic esophagitis 

EoE is a chronic condition. You will need to manage it for the rest of your life. This includes staying away from the foods or allergens that cause your allergic reaction. In many cases, you will need to stay on medicines.

It’s important to work closely with your gastroenterologist. He or she can tell you when you need tests to see if the EoE is getting better or worse. An allergist and dietitian can help you manage related problems such as asthma, allergic rhinitis, and food allergies.

Also consider joining a support group or checking out a group such as the American Partnership for Eosinophilic Disorders (APFED) for tips on coping with EoE.
