Atopic dermatitis, also known as eczema, is a chronic, inflammatory skin condition that can cause red, itchy, scaly patches to appear on the skin. The condition is often associated with allergies and can spread if not properly treated.
The primary cause of atopic dermatitis spreading is contact with an allergen. Allergens can come from the environment, such as pollen, animal dander, or certain fabrics, or they can be triggered by certain foods. When these allergens come into contact with someone’s skin, it can trigger an inflammatory response, resulting in the spread of the condition.
In addition to contact with allergens, stress can also trigger the spread of atopic dermatitis. Stress can cause an increase in cortisol, a hormone that can lead to inflammation and dryness of the skin. This, in turn, can lead to more intense itching, which can cause scratching that further exacerbates the condition.
Skin irritants can also cause atopic dermatitis to spread. Certain soaps, detergents, or perfumes can cause inflammation when they come into contact with the skin. This can lead to further irritation of the skin, leading to a spread of the condition.
In some cases, genetics may also play a role in the spread of atopic dermatitis. Certain genetic mutations can make someone more prone to developing the condition or make it more likely to spread.
Finally, the spread of atopic dermatitis can also be caused by a weakened immune system. If the body is unable to fight off allergens or other irritants, it can lead to a spread of the condition.
Overall, atopic dermatitis can spread when it comes into contact with allergens, irritants, stress, or when the immune system is weakened. It is important to identify and avoid triggers, and to use treatments to reduce inflammation and itching.
