Eczema and Food Allergies
Although the role of food allergies and eczema is controversial, there is no good reason why a lactose-free formula would help a child’s eczema. If a child did have an allergy to a baby formula, it would likely be to either the milk proteins or soy proteins and not to lactose, which is a sugar.
The lactose-free formula may have improved other symptoms, such as gas, fussiness, or diarrhea, but it is unlikely that it would have made his eczema better, so that may have been a coincidence.
If you really think that your baby’s formula, including a milk-based and soy formula, is making his eczema worse, then you might talk to your pediatrician about trying a hypoallergenic formula, such as Nutramigen or Alimentum.
Allergy testing, using an allergy skin test blood test like the Immunocap, could be another option.
It is thought that “In some sensitized patients, particularly infants and young children, food allergens can induce urticarial lesions, itching, and eczematous flares, all of which may aggravate AD (atopic dermatitis).”
Other Eczema Triggers
Keep in mind that many experts still do not believe that food allergies are a big trigger for eczema, though, so most parents should not go out of their way to restrict their child’s diet without talking to their pediatrician first. Of course, if your child’s eczema gets worse every time you give your child something to eat or drink, then it likely is a trigger for him and you should avoid it and talk to your pediatrician about food allergies.
Up to 30% of eczema patients have food allergy and will develop symptoms such as hives, itching, eczema , respiratory and gastrointestinal symptoms when expose or consume food they are allergic to. The most common food allergens that cause skin reactions are milk, egg, soy, peanut, tree nuts, wheat, fish and shellfish.
