Eosinophilic esophagitis, or EoE, is a condition where specific white blood cells called eosinophils build up in the lining of the esophagus (the tube that carries food to the stomach). Since there are normally no eosinophils located in the esophagus, the result of their presence is inflammation and pain.

Both children and adults can develop EoE. The exact cause is not known, but it is likely an allergic reaction to certain foods or substances in the environment, such as dust mites or pollen. People who have asthma, eczema or hay fever are more likely to develop EoE. Some people with this condition eventually develop chronic scarring called strictures, which cause the esophagus to narrow.

Allergists, gastroenterologists, registered dietitians and others play a role in treating this condition. At Orlando Health Arnold Palmer Hospital Center for Digestive Health and Nutrition, our experts treat children and adults with EoE.
