Eosinophilic Esophagitis (EoE) - Epidemiology Forecast - 2036

Eosinophilic Esophagitis Insights and Trends

• Eosinophilic esophagitis, once considered rare, has shown a marked rise in prevalence over the past two decades. Since 2009, prevalence has increased nearly fivefold, with US estimates rising from ~56.7 per 100,000 to ~142.5 per 100,000, driven largely by improved diagnostic awareness and healthcare utilization.
• EoE incidence has steadily increased across Europe over the last three decades, but reported rates remain lower and more variable than in North America, likely due to underdiagnosis and limited research. Standardized, Europe-wide epidemiologic studies are needed to clarify the true disease burden.
• The gold standard for diagnosing and monitoring EoE remains esophageal biopsy demonstrating eosinophilic infiltration limited to the esophagus. However, diagnosis is challenging due to non-specific, overlapping symptoms and the absence of validated noninvasive biomarkers, often leading to delayed identification. Despite advances in EoE diagnosis and treatment, the persistent lack of specific biomarkers represents a key unmet clinical need, underscoring the need for further research and development of noninvasive diagnostic tools.
• A continuous increase in EoE incidence and prevalence rates has been reported both in children and adults over the last two decades. This increase in prevalence and incidence of EoE seems to be outpacing the improvement in disease recognition, and a plateau has not yet been reached. The prevalence of EoE appeared to be higher in adults than in children.
• EoE incidence and prevalence have steadily increased over the past two decades in both children and adults, with rates rising faster than improvements in disease recognition. Prevalence is higher in adults than in children, and no plateau has yet been reached. Males represent the majority of EoE cases, accounting for approximately 65% of patients.

DelveInsight's "Eosinophilic Esophagitis (EoE) - Epidemiology Forecast - 2036" report delivers an in-depth understanding of Eosinophilic Esophagitis (EoE), historical and forecasted epidemiology of Eosinophilic Esophagitis (EoE) in the United States, EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan.

Eosinophilic Esophagitis (EoE): Understanding

Eosinophilic Esophagitis Overview

Eosinophilic Esophagitis (EoE) is an emerging chronic inflammatory disease of the esophagus characterized by upper gastrointestinal symptoms, including dysphagia and esophageal food impaction. The histopathological manifestations involve intraepithelial infiltration of eosinophils (=15 Eos/HPF) and remodeling of the esophageal epithelium, including Basal Zone Hyperplasia (BZH) and Dilated Intercellular Spaces (DIS), which can lead to strictures and narrow-caliber esophagus.

EoE is a complex disease characterized by heterogeneous clinical presentation (age of onset, symptomology, varying clinical manifestations and comorbidities, natural history, and responsiveness to therapy). Despite challenges in disease diagnosis and management, there is corroborative clinical and experimental evidence to suggest that EoE is driven by an underlying CD4+ T helper type 2 (Th2) allergic inflammatory response to dietary food allergens in the esophageal mucosa.

Eosinophilic Esophagitis Diagnosis

EoE is characterized by clinical symptoms of esophageal dysfunction and esophageal eosinophilia, defined by =15 Eosinophils per High-powered Field (Eos/HPF) on biopsy. Before solidifying a diagnosis of EoE, clinicians should consider other etiologies of esophageal eosinophilia. Endoscopy, Barium Esophagram, Reflux testing, Impedence planimetry and others methods are used for the diagnosis of EoE.

Eosinophilic Esophagitis Epidemiology

The Eosinophilic Esophagitis epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by the Total Diagnosed Prevalent Cases of Eosinophilic Esophagitis, Gender-specific Cases of Eosinophilic Esophagitis, Age-specific Cases of Eosinophilic Esophagitis, Treated Cases of Eosinophilic Esophagitis in the 7MM covering the United States, EU4 (Germany, France, Italy, and Spain) and the United Kingdom, and Japan from 2022 to 2036.

• In the 7MM, the US accounted for the highest diagnosed prevalent cases of eosinophilic esophagitis in 2025, with around 512,000 cases; these numbers are expected to increase during the forecast period.
• Eosinophilic Esophagitis predominantly affected males, with approximately 332,000 males diagnosed compared to 179,000 females in 2025 in the US.
• In the EU4 and the UK, individuals over the age of 18 were the most affected by Eosinophilic Esophagitis, with approximately 395,000 cases reported in 2025.
