Eczema, also known as atopic dermatitis, is a common skin condition that causes dry, itchy, and inflamed skin. The exact cause of eczema is not fully understood, but it is believed to be a combination of genetic and environmental factors. Some of the common causes and triggers of eczema include:
-
Genetic predisposition: People with a family history of eczema are more likely to develop the condition themselves. Research has shown that children who have one or both parents with atopic eczema, or who have other siblings with eczema, are more likely to develop it themselves.
-
Overactive immune system: Atopic dermatitis, the most common type of eczema, results from an overactive immune system that causes the skin barrier to become dry and itchy.
-
Environmental triggers: Eczema symptoms can flare up when exposed to certain environmental triggers, such as irritants or allergens. Common triggers include dry air, extreme heat or cold, soaps, detergents, shampoos, and specific allergens like house dust mites, pet fur, pollen, and molds.
-
Skin barrier function: Eczema weakens the skins barrier function, which is responsible for helping the skin retain moisture and protecting the body from outside elements.
-
Hormonal changes: Women may find their symptoms get worse in the days before their period or during pregnancy due to hormonal changes.
-
Stress: Some people report that their symptoms get worse when they are stressed.
Its important to note that eczema triggers can vary from person to person, and identifying individual triggers and avoiding them can help reduce the risk of eczema flare-ups in the future. While there is no cure for eczema, there are treatments available to manage the symptoms and provide relief.
