Eosinophilic gastro–intestinal disorder is an uncommon disorder presenting with non–specific gastrointestinal symptoms. It is diagnosed by demonstrating eosinophilic infiltration of gut wall after excluding other causes of eosinophilia. It is likely a hypersensitivity response to food allergen. The most common symptoms of patients are abdominal pain, nausea, vomiting, early satiety, and diarrhoea. It responds well to corticosteroids. We hereby present two cases – eosinophilic esophagitis and eosinophilic duodenitis– seen in a span of one month, presenting with vague gastro–intestinal symptoms for over a year. Their endoscopic biopsy showed eosinophilic infiltration of mucosa. The aim of presenting the cases is to increase awareness of this disorder as high index of suspicion is necessary to diagnose these patients.
