The allergic child.

Allergies may cause gastrointestinal symptoms such as diarrhea, vomiting and pain, dermatologic manifestations, asthma and rhinitis. The most common offender among the foodstuffs is milk. Elimination diets are designed not only to remove the offending food but to identify it and to prevent new sensitizations. Canker sores, foul breath and even enuresis may occasionally be related to allergies.
