Your paediatrician and/or paediatric specialist will want to monitor growth, weight, ongoing signs and symptoms, and objective measures of food allergy. As a rule, this should be done at least once a year.
Many, but not all, children outgrow their food allergies. This can vary for different foods and depends on the individual child. The majority of children who are allergic to milk will shed this allergy by the age of 3-5 years. The re-evaluation process may include skin testing, RAST analysis, and/or oral food challenges dependent on the type of the allergic reaction. With early onset symptoms such as skin rash or swelling the allergy is triggered by immunoglobulin E (IgE). In this case IgE-skin or blood tests would be performed. The other type of food allergy is called non-IgE-mediated food allergy and symptoms appear several hours or days after the food is eaten such as eczema, diarrhoea or failure to thrive. Of course, some children show mixed reactions.
So don’t start worrying too soon if your child still shows positive in skin test or RAST! This does not necessarily mean that CMA has not been outgrown. In the end, a food challenge under the direction of a paediatric specialist may be necessary to prove that CMA has finally gone away.
Ask your child’s doctor for regular check-ups. They should be done after the age of 12 months and no sooner than 6-12 months after the last bout of allergic reactions.
