Allergic Colitis

Allergic colitis (food protein-induced allergic proctocolitis) is common in infants, due to cow's milk/soy protein allergy, presenting with blood-streaked stools, mucus, and fussiness, usually without systemic illness. Treatment: hypoallergenic formula (extensively hydrolyzed/amino acid) or maternal elimination diet if breastfed; eliminate cow's milk/soy; supportive care; rule out infection/IBD/anal fissure; most resolve by 1-2 years; follow-up growth; reintroduce foods gradually.
