<unk>  is a non IgE immunological reaction against food protein antigens, particularly cow-milk and soy proteins. The exact mechanism is not known. It usually develops insidiously, and is believed to be T-cell mediated.<unk>  is most commonly caused by allergy to cow's milk protein. Symptoms and signs of<unk>  are non-specific and observed in other causes of colitis and some systemic diseases. Detailed history and physical examination is needed to make the diagnosis. In addition, endoscopy with biopsy may be required to confirm the diagnosis. The exact prevalence of<unk>  is unknown.<unk>  typically develops in early infancy.<unk>  is benign, resolving completely in most children without any sequelae. The most common symptoms of<unk>  is passage of blood streaked stool in an otherwise healthy young infant. There are no specific laboratory findings that are pathognomonic of<unk> . Laboratory studies should therefore be correlated with a carefully taken history and a detailed physical examination. Presence of eosinophils in the stool is suggestive of<unk>  in the presence of typical clinical findings. The mainstay of treatment of<unk>  is dietary management. Medical therapy includes allergen avoidance, treatment of severe manifestations of the allergy, and eventual reintroduction of the allergy into the diet.
