Atopic dermatitis (AD) is a chronic inflammatory skin condition characterized by dry, itchy skin and patches of eczema. It is sometimes referred to as eczema. The cause of AD is not fully understood, but a combination of genetic and environmental factors are thought to be involved.
AD is not caused by either bacteria or fungi. While bacterial or fungal infections may occur due to scratching and breaking of the skin, the primary cause of the condition is not believed to be either of these.
The most common type of AD is caused by an overactive immune response to certain environmental triggers such as allergens, irritants, or stress. This type of response leads to inflammation and itching of the skin.
AD may also be caused by biological factors, such as a defect in the skin’s barrier function. This defect prevents the skin from properly retaining moisture, leading to dryness, itching, and flaking.
In addition, AD can be caused by hormonal changes, such as those associated with puberty or pregnancy. In some cases, an underlying medical condition, such as diabetes or an endocrine disorder, may be associated with AD.
The treatment of AD depends on the cause and severity of the condition. The primary goal is to reduce inflammation and itching. This may involve topical creams and ointments, antihistamines, or other medications.
In more severe cases, ultraviolet light therapy or even systemic medications may be recommended. In some cases, immunosuppressants may be used to control the condition.
In summary, atopic dermatitis is not caused by either bacteria or fungi. It is primarily caused by an overactive immune response and may be associated with other medical conditions. Treatment is based on the cause and severity of the condition and may involve topical creams, antihistamines, ultraviolet light therapy, and systemic medications.
