Food Allergies And Eczema – Is There any Connection?

Link Between Eczema and Food Allergies

There is now a direct link between eczema and food allergies. While atopic dermatitis may be triggered or worsened by common food allergies such as those to eggs, milk, wheat, soy, and peanuts, eczema itself may be responsible for the development of food allergies in the first place.

Food allergies are considered official comorbidity (related health condition) of atopic dermatitis alongside asthma, allergic rhinitis (hay fever) and depression. As a result, they believe that if they could just cut certain foods from their diets, such as gluten or dairy, their eczema will go away.

Eczema is a serious skin condition that can cause itchy skin rashes, skin irritation and oozing blisters. It can also result in the flaky patches in severe condition. The cause of eczema is still not known but hereditary and environmental triggers usually play a major role in developing skin condition. The eczema symptoms may get worse as soon as a patient comes in the direct contact with the allergens/irritants.

Have you ever had eczema as a child and now usually develop hay fever, asthma or skin allergies as an adult? Is your child developing red, irritated, itchy, flaky patches on the skin? There may be few questions that you might have in your mind:

  • Can eczema be caused by food allergies?
  • What food to avoid when you have eczema?
  • What are the most common food allergies?
  • Are allergies and eczema related?
  • Does food allergy cause eczema?
  • What foods cause eczema to flare up?

If this is the case then as per various studies if one or both parents have eczema, seasonal allergies or asthma then a child is more likely to have eczema. Children suffering from the same may be more at a risk of getting allergies that particularly includes food allergies.

Understanding the connection between the same can help you manage the skin condition. Food Allergy can be considered as one of the main causes of eczema for the young children.  This may be noted that many people who have eczema are also diagnosed with the food allergies.

The food challenge is conducted under strict medical supervision in which the patient is given tiny amount of the suspected food in the increasing dosage over a specific time period, followed by few hours of analysation and observation as to see if any reaction occurs or not.

This is helpful in those cases when the patient’s medical history, skin tests or blood tests are unclear.
