Although there have been many studies on the diagnosis and treatment of eosinophilic esophagitis (EoE), there have been little on eosinophilic gastroenteritis (EoG) (EGE). Fortunately, research into epidemiology, as well as detection and management of this disorder, has recently increased.

Both EoE and EGE are becoming more popular, according to reports. While no consensus has been reached, plasma concentrations of thymic stromal lymphopoietin and IL-33 can be useful as biomarkers for effective diagnosis, whereas increased eosinophil infiltration in gastrointestinal tissue remains a crucial factor. Recently tested treatments include topical glucocorticoid administration, an elimination diet, and molecular target therapy with neutralising antibodies. EGE, among other allergic disorders, seems to be on the rise. Several research programmes on disease detection and recovery are currently underway.
