Causes
The exact cause of eczema is not fully understood, but it is believed to result from a combination of genetic, environmental, and immune system factors.
1. Genetic Factors:
Family history of eczema, allergies, or asthma increases the risk.
Mutations in the filaggrin gene, which helps maintain the skin barrier.
2. Environmental Triggers:
Allergens (pollen, dust mites, pet dander).
Irritants (soaps, detergents, fragrances).
Weather changes (cold, dry air or heat).
Sweating or excessive dryness.
3. Immune Dysregulation:
Overactive immune responses to triggers lead to inflammation.
4. Other Triggers:
Stress.
Hormonal changes (e.g., during pregnancy or menstruation).
Certain foods (dairy, nuts, or wheat in some cases).
