Milk Allegry Statistics:
Cow's milk allergy (CMA) is the most common food allergy in young children, but is uncommon in adults. This food allergy presents with a wide range of clinical syndromes due to immunologic responses to cow's milk proteins that can be immunoglobulin E (IgE)- and/or non-IgE-mediated. Studies in several countries around the world show a prevalence of milk allergy in children in the first year of life of around 2% to 5%. Many children lose their hypersensitivity to milk by age 3, but some children remain allergic for a lifetime.
Often, children with a milk allergy will have a "slow" reaction, which means symptoms will develop over time—perhaps within several hours to days later. Symptoms associated with a slow reaction are: abdominal cramps, loose stool, diarrhea, skin rash, intermittent coughing, runny nose or sinus infection, failure to thrive.
Milk Allergy Management and Treatment:
It is recommended that formula-fed infants who are allergic to milk use an extensively hydrolyzed, casein-based formula. This type of formula contains protein that has been extensively broken down so it is different than milk protein and not as likely to cause an allergic reaction. Examples of casein-hydrolysate formulas are Alimentum and Nutramigen. If the child is not allergic to soy, his or her doctor may recommend a soy-based formula.
