A baby with hiatal hernia presenting with severe iron-deficiency anemia

Hiatal hernia (HH) is a condition that develops as a result of a developmental defect of the diaphragm, occurs rarely in the childhood age group, and is frequently asymptomatic (1). Iron deficiency anemia is observed frequently in children and results from factors that increase the need for iron including insufficient intake, malabsorption or bleeding in the gastrointestinal system (GIS) (2). Here, we report a baby who was followed up with a diagnosis of iron deficiency anemia for a long period, suspected because of abnormal air density in the lower right-middle mediastinal region on lung radiography obtained because of respiratory tract infection, and was diagnosed as having HH with barium esophagogastroduodenal (EGD) imaging.
