What causes Atopic Dermatitis?
Research has identified several factors that can contribute to developing atopic dermatitis. These may include: (4)
- Genetics: People with a family history of atopic dermatitis or other allergic conditions such as asthma, hay fever, or hyperactive airway diseases are more likely to develop this condition.
- Environmental triggers: Certain environmental factors, such as exposure to allergens, irritants, temperature changes, or humidity, can trigger atopic dermatitis flare-ups.
- Immune system dysfunction: People with atopic dermatitis have an overactive immune system. It causes the body to react to harmless substances, leading to inflammation and skin irritation.
- Skin barrier dysfunction: The skin of people with atopic dermatitis is often deficient in lipids, leading to dryness and increased susceptibility to environmental irritants.
- Microbial factors: Certain bacteria or viruses on the skin may trigger or worsen atopic dermatitis symptoms.
- Stress: Emotional stress can cause the release of certain hormones that can worsen atopic dermatitis symptoms.
It is important to note that atopic dermatitis is a complex condition, and multiple factors can contribute to its development. Therefore, a comprehensive approach to management that considers all possible causes and triggers is essential for successful treatment.
