Atopic dermatitis (eczema): symptoms and causes


Atopic dermatitis, or eczema, is a chronic skin disease characterised by red, intensely itchy skin and lesions accompanied by dryness. The condition mainly affects children but may persist into adulthood. It is essential to know the symptoms and causes of this condition to treat it properly. If you have this disease in your family, we welcome you to EgoDent, where our specialists will find the best treatment for your child.

How does atopic dermatitis manifest itself?

Atopic dermatitis (eczema) can manifest differently, but some common symptoms characterise this skin condition. Here, you can learn how atopic dermatitis can manifest itself:

Severe itching 

One of the characteristic symptoms of atopic dermatitis is severe itching or pruritus of the skin. This itching can be so powerful that it can lead to scratching and further skin damage.

Dry skin

People with atopic dermatitis often have dry and sensitive skin, which may be more pronounced in skin folds such as the elbow and knee joints.

Erythema (redness)

The area affected by eczema is often red, and small bumps or fluid-filled blisters sometimes appear.


Characteristic lesions include cracking, peeling skin, and crusting. In more severe cases, the skin may become inflamed and even bleed.

Secondary infections

Due to skin injuries and scratches, there is a risk of secondary infections of the skin.

What causes atopic dermatitis?

Atopic dermatitis is a complex and multifactorial disease, meaning it can have multiple causes that work together to trigger and maintain symptoms. Some of the known causes of atopic dermatitis are:

Genetic factors

A family history of atopic dermatitis increases the likelihood of developing the condition. This indicates that there is a genetic component involved in the development of the disease.

Skin barrier dysfunction

In people with atopic dermatitis, the skin’s barrier function may be impaired. As a result, the skin is not adequately hydrated and cannot protect itself from harmful external factors.

Allergic reactions

Food allergies, environmental allergens (such as pollen or dust), and hypersensitivity to cosmetics can aggravate the symptoms of atopic dermatitis or lead to its onset.

Exaggerated immune response

Atopic dermatitis has an exaggerated immune response to certain substances or irritants that come into contact with the skin, leading to inflammation and itching.

Environmental factors

Certain environmental factors, such as extreme temperatures, low humidity, and dry air, can exacerbate the symptoms of atopic dermatitis.

In summary, atopic dermatitis (eczema) is a chronic skin condition that causes severe itching, redness, and skin lesions. Treatment of this condition includes avoiding triggers, maintaining adequate skin hydration, and using medical treatments recommended by a specialist.
