Connection between Eczema and Food Allergies Exploration
Atopic dermatitis, commonly known as eczema, and food allergies are associated but distinct conditions. Research has shown that eczema typically develops first, often in early childhood, and is a complex inflammatory skin condition influenced by genetic and environmental factors.
Children with moderate to severe eczema have an increased risk of developing both environmental and food allergies. However, it is important to note that food allergies are not the primary cause of eczema itself. Instead, the presence of eczema reflects an underlying atopic tendency that also predisposes to food allergies.
Empiric food elimination diets to treat eczema are not routinely recommended, as foods are not usually the cause of eczema flare-ups. Unwarranted elimination can be harmful, and early introduction of allergenic foods has been found protective against food allergies, with delay potentially increasing the risk.
While food allergies can trigger eczema flares in certain individuals, especially with allergens like dairy or peanuts, this is not universal or the main driver of eczema. There is no strong evidence that food allergy reaction severity directly correlates with eczema severity or that food allergy underlies eczema severity.
A monitored nutritional program is recommended for children on an elimination diet for atopic dermatitis. Symptoms of a food allergy may last as long as the person continues to eat the food they are allergic to. It is essential to consult a doctor to perform a test to diagnose a food allergy before eliminating foods from one's or their children's diets.
A 2020 review suggests that an imbalance of skin bacteria and disruption of the skin barrier can leave people susceptible to food allergies. Other studies indicate that digestive dysfunction and food may play a part in the development of atopic dermatitis.
It is crucial to remember that atopic dermatitis is a disease that involves many more body systems than the skin. Changing the diet of a child with atopic dermatitis rarely prevents flare-ups, according to the AAD. The National Eczema Association advises that eating certain foods can trigger an immune system reaction that may cause eczema symptoms, but allergy tests may not always show positive results.
In severe cases, food allergies can cause immediate and severe reactions such as hives, vomiting, and anaphylaxis. It is essential to manage both conditions appropriately, with a healthcare professional's guidance, to ensure the best possible outcome for those affected.
