Eosinophilic esophagitis is an inflammation in the esophagus, the tube that delivers food from your mouth to your stomach. The swelling can make it difficult to swallow.

Eosinophilic esophagitis is caused by a build up of eosinophils in the esophagus. Eosinophils are a type of white blood cell. They gather in tissue during an allergic reaction and cause swelling. Eosinophils should not be found in the esophagus.

It is not clear why this happens. It is a problem with the immune system that may be a reaction to things in the air or an allergy to some food.

Risk Factors

The risk of eosinophilic esophagitis may be higher in those with:


Symptoms may include:

  • Hard time swallowing
  • Food gets stuck in the esophagus
  • Nausea and vomiting
  • Poor weight gain
  • Unexplained weight loss
  • Babies may refuse to breastfeed or take a bottle
  • Burning in throat similar to heartburn
  • Stomach ache


The doctor will ask about child’s symptoms and past health. A physical exam will be done.

An endoscopy may be done. The doctor can use the scope to examine the esophagus. A sample of tissue may also be taken. The lab can look for signs of problems such as eosinophils.

A specialist may be needed for diagnosis or treatment. An immunologist focuses on allergies.


Eosinophilic esophagitis cannot be cured. Treatment can help manage the symptoms. Steps may include:

Find and Avoid Allergens

Some foods or allergens like mold, pollen, or dust can make swelling worse. Allergy tests can help to find what is causing problems. An elimination diet may help to find what foods are making swelling worse. This type of diet works best if done with a dietitian or doctor.

Once allergens are known, steps can be taken to avoid or reduce contact with them. This can decrease swelling and other symptoms.


Medicine will be based on each persons needs. Some medicine that may help includes:

  • Steroid medications may help control swelling in the esophagus. It may be taken as pills or inhaled mist.
  • Proton pump inhibitors to treat gastroesophageal reflux disease (GERD) if present.


There are no steps to prevent eosinophilic esophagitis.
