Atopic Dermatitis (Eczema)

Atopic dermatitis, known as Eczema, is a chronic inflammatory skin condition characterized by dry, itchy, and inflamed skin. Eczema can affect people of all ages, but it is most commonly diagnosed in infants and young children.

The condition is typically marked by flare-ups, during which the skin becomes red, itchy, and inflamed, and periods of remission, during which the skin may be less affected. There are several types of atopic dermatitis or Eczema.

Contact Dermatitis – It is a type of skin inflammation that occurs when the skin comes into contact with a substance that causes irritation or triggers an allergic reaction.

Dyshidrotic Eczema – Pompholyx is another name for this type of Eczema that causes small, itchy blisters to develop on the hands and feet.

Hand Eczema – It is a common skin condition affecting the hands and fingers. It makes skin dry and itchy and sometimes leaves painful patches.

Neurodermatitis –   Also known as lichen simplex chronicus, it is a skin condition characterized by chronic itching and scratching.

Nummular Eczema – It causes circular or oval-shaped patches of dry, itchy skin to develop on the arms, legs, and torso.

Stasis Dermatitis –    It is venous Eczema. It is a skin condition that occurs in the lower legs when there is poor circulation in the veins.

Symptoms

Eczema can impact anyone at any age. Symptoms typically begin during childhood and last into adulthood. Symptoms of Eczema may include:

  • Dry, scaly, or cracked skin
  • Red or inflamed skin
  • Itching or burning
  • Bumps or blisters that may ooze or crust over
  • Thickened or leathery skin in the affected areas
  • Discolouration or changes in skin pigmentation

Causes

This chronic inflammatory skin condition is often caused by a combination of multiple factors, including genetic, environmental, and immunological. The main causes of the skin condition include:

  • Genetics: Atopic dermatitis tends to run in families, and genetic variations that increase the risk of developing the condition have been identified. People with a family history of atopic dermatitis, allergies, or asthma are at a higher risk of developing the condition.
  • Immune System Dysfunction: If you have atopic dermatitis, you have an overactive immune system that responds to triggers such as allergens and irritants. This causes inflammation in the skin and can lead to eczema flares.
  • Environmental Factors: Certain environmental factors can trigger or exacerbate atopic dermatitides, such as dry skin, hot or cold weather, low humidity, exposure to allergens (such as pollen or pet dander), or irritants (such as harsh soaps or detergents).
  • Skin Barrier Dysfunction: Atopic dermatitis weakens your skin barrier, which allows irritants and allergens to penetrate the skin more easily, leading to inflammation and eczema flares.

Risk Factors

If you’re prone to allergies or have had Eczema, asthma, or hay fever, you can develop atopic dermatitis. You can also suffer from the skin condition if your family members have had Eczema.

Diagnosis & Complications

Your dermatologist needs to review your family history and  conduct a medical examination to diagnose atopic dermatitis.

There is no specific test for atopic dermatitis. Still, the doctor may perform a skin biopsy or allergy testing to rule out other skin conditions or identify any allergens that may exacerbate the condition.

Eczema is a chronic condition that can significantly impact quality of life. It may be associated with sleep disturbances, skin infection, social isolation, and other complications.

Treatment & Prevention

Treatment options may include topical or oral medications to reduce inflammation and lifestyle changes to minimize exposure to triggers and improve skin hydration. Remember that you cannot prevent atopic dermatitis entirely. But there are steps you can take to reduce or manage the symptoms.

For instance, you can avoid the triggers, use gentle skin care products, apply moisturizer, manage stress, and treat skin infections promptly.

While these steps cannot completely prevent atopic dermatitis, they can help manage symptoms and reduce the risk of a flare. It’s important to work closely with a healthcare provider to develop a treatment plan that works best for you.
