Eosinophilic esophagitis is a chronic inflammation of the esophageal mucosa caused by an immune-allergic reaction, in which white blood cells of the type eosinophils (Eosinophils) accumulate in the esophageal wall. This condition leads to persistent inflammation and structural changes in the tissue, which can result in narrowing of the esophagus and impaired swallowing function.
The disease frequently appears in individuals with an allergic tendency (such as asthma, allergic rhinitis, or eczema) and is considered an allergic response to certain food components or environmental factors.
Diagnosis is performed via gastroscopy and collection of biopsies from the esophageal wall, in which an increased presence of eosinophils is observed. In some cases, it is necessary to assess food sensitivities through an allergist.
