Eosinophilic esophagitis (EoE) (related)

Eosinophilic esophagitis is an immune-driven condition of the esophagus, the tube connecting the throat to the stomach, and it is generally considered allergic and immune-mediated rather than classically autoimmune. Research describes the process as beginning when exposure to food or environmental allergens causes the esophagus lining to release signaling proteins that draw eosinophils, a kind of white blood cell, into the esophageal tissue. Over time this drives inflammation and narrowing of the esophagus, which can cause swallowing difficulty and, less often, food becoming stuck.

A 2021 review published in JAMA estimated that EoE affects roughly 34 people per 100,000 in Europe and North America, and its recognized prevalence has risen over recent decades. It occurs in children and adults and is associated with other allergic conditions such as asthma and eczema.

Common signs

In adults and teens, trouble swallowing is common, along with the sensation of food sticking and, at times, food getting truly stuck (impaction), plus chest or upper-abdomen discomfort and heartburn that does not respond to usual reflux care. Young children may show feeding difficulty, vomiting, pain, or poor weight gain, sometimes mistaken for reflux.
