Allergies and Eczema: What’s the Link?

Eczema and allergies are frequently associated with one another. An allergic disorder involving the skin, eczema is characterized by uncomfortable, red, and irritated patches. An allergic reaction occurs when the body’s immune system overreacts to a substance that it erroneously perceives as a danger. Various kinds of allergens can cause allergic responses, including:

- Food: Some foods like peanuts, milk, eggs, soy, and wheat have the potential to cause eczema in some individuals.

- Dust mites: Microscopic creatures that reside inside soft home goods, including bedding and carpets, are known as dust mites.

- Pet Dander: The skin flakes of cats, dogs, and other animals make up pet dander, which can aggravate eczema in some people.

- Pollen: Plants release pollen as a reproductive method. Eczema can be triggered in certain persons by pollen from grasses, trees, and weeds.

- Chemicals: Individuals with eczema may experience flare-ups as a result of coming into contact with certain substances like those found in cleaning supplies, soaps, and cosmetics.

Several things might happen when the body comes into interaction with an allergen:

- IgE-Mediated (Immediate) Reaction: When the body encounters an allergen, it initiates the creation of antibodies known as Immunoglobulin E (IgE) antibodies. These antibodies subsequently adhere to mast cells, specialized cells dispersed throughout the body, notably the skin. When the same allergen is encountered once again, it binds to the IgE antibodies on the mast cells, prompting the release of inflammatory chemicals including histamine. This swift, allergy-like response can result in symptoms such as hives, swelling, and itching, along with increased blood flow and fluid to the location.

- Non-IgE-Mediated (Delayed) Reaction: Sometimes, an allergic reaction can take longer to develop than is typical for an allergy. Instead of IgE antibodies, immune cells such as T-cells are involved in this non-IgE-mediated reaction. After being subjected to an allergen, these T-cells recognize and attack it. The ensuing inflammatory reaction results in symptoms like eczema, which can manifest as red, irritated, dry, or scaly skin patches.

If you suffer from eczema and believe allergies might be the underlying cause, it is essential to get in touch with a healthcare practitioner for an accurate diagnosis and appropriate treatment. They can conduct allergy testing to identify the offending allergens and guide you in developing strategies for avoiding them and handling flare-ups.
