Atopic dermatitis, also known as eczema, is a chronic skin condition that can cause dry, scaly, and itchy skin. It is most commonly seen in children, but can also occur in adults. While atopic dermatitis is often associated with allergies, it is important to note that not all cases are caused by allergies.
In some cases, atopic dermatitis is caused by a combination of environmental and genetic factors. These factors can include exposure to certain irritants, such as soaps, detergents, and fragrances; exposure to extreme temperatures and humidity; and a family history of atopic dermatitis. In addition, some people may have an increased sensitivity to certain allergens, which can trigger a flare-up of atopic dermatitis.
However, for many people, atopic dermatitis is caused by an allergic reaction to a specific allergen. Common allergens that can trigger a flare-up of atopic dermatitis include pollen, dust mites, animal dander, and certain foods. If a person is allergic to one of these substances, their skin may become red, dry, and itchy when they come into contact with it.
It is important to note that not all cases of atopic dermatitis are caused by allergies. While allergies may be a contributing factor in some cases, it is important to speak to a doctor to determine the exact cause of the condition. A doctor can help to identify the underlying cause of the atopic dermatitis and recommend the best treatment plan.
