Observation:
- A pediatric case presented with diarrhea, later developing urticaria and wheezing.
- Symptoms were attributed to intolerance to various forms of egg and egg-derived products.
Findings:
- A strict hypoallergenic diet, eliminating all egg components (whole egg, yolk, white, lysozyme, ovalbumin), was implemented.
- The diet was made more palatable by including readily available, manufacturer-verified egg-free food products.
Implications:
- Strict avoidance of egg allergens can effectively manage symptoms in children with egg intolerance.
- Careful dietary planning and product selection are key to successful long-term management.
- This case highlights the importance of comprehensive allergen identification and patient-centered dietary interventions.
