Dysphagia is one of the symptoms that can occur (along with several others) in infants with cow’s milk-related functional gastrointestinal disorders (FGIDs).1
It is commonly a persistent, recurrent gastrointestinal symptom seen for example in patients with eosinophilic esophagitis (EoE).2
In a review of the evidence from North America and Europe, they reported dysphagia to be the most common symptom in children with EoE along with emesis and abdominal pain.3
