Eczema
Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by inflammation, redness, dryness, and itchiness. It typically develops in early childhood but can occur at any age. Eczema often appears in cycles, with periods of flare-ups followed by times of remission. The exact cause of eczema is not fully understood, but it is believed to be linked to a combination of genetic, immune system, and environmental factors.
Common Symptoms of Eczema-Common Areas Affected
-
Dry, sensitive skin.
-
Red, inflamed patches.
-
Itching (which can be severe, especially at night).
-
Crusting or oozing lesions.
-
Thickened, scaly skin (lichenification) due to scratching.
-
Swelling or fluid-filled blisters.
-
Darkening of the affected skin after repeated inflammation.
-
Face, especially in infants.
-
Elbows, knees, and wrists.
-
Hands and feet.
-
Scalp and neck.
-
Around the eyes.
Types of Eczema-Causes of Eczema
-
Atopic Dermatitis: The most common type, often associated with other allergic conditions like asthma and hay fever.
-
Contact Dermatitis: Caused by skin contact with irritants or allergens.
-
Dyshidrotic Eczema: Characterized by small, itchy blisters, usually on the hands and feet.
-
Nummular Eczema: Appears as round, coin-shaped spots on the skin.
-
Seborrheic Dermatitis: Often occurs on the scalp and causes dandruff-like flakiness (cradle cap in infants).
-
Stasis Dermatitis: Occurs due to poor circulation, often in the lower legs.
-
Genetics: A family history of eczema, asthma, or allergies can increase the likelihood of developing the condition.
-
Immune System Dysfunction: Eczema is thought to be caused by an overactive immune response to environmental triggers.
-
Skin Barrier Defects: Eczema patients often have a compromised skin barrier, making it harder for the skin to retain moisture and protect against irritants.
-
Environmental Factors: Exposure to irritants like harsh soaps, detergents, chemicals, and allergens (dust mites, pet dander, pollen) can trigger or worsen eczema.
-
Climate: Dry, cold, or humid weather conditions can influence the severity of eczema.
-
Stress: Emotional stress can exacerbate eczema symptoms.
Treatment Options
-
Moisturizers: Regular use of thick creams or ointments (e.g., petrolatum-based) helps maintain skin hydration and improve the skin barrier function.
-
Topical Corticosteroids: Anti-inflammatory creams or ointments that reduce redness, itching, and swelling during flare-ups.
-
Topical Calcineurin Inhibitors: Non-steroidal creams (e.g., tacrolimus or pimecrolimus) that help suppress the immune response and reduce inflammation.
-
Antihistamines: To relieve itching, especially at night.
-
Oral or Topical Antibiotics: If the skin becomes infected.
-
Phototherapy: Controlled exposure to ultraviolet (UV) light can reduce inflammation and improve skin symptoms.
-
Biologic Therapies: Newer treatments, such as dupilumab (Dupixent), target the immune pathways involved in eczema.
-
Avoiding Triggers: Identifying and minimizing exposure to known triggers (allergens, harsh chemicals, or specific foods) can help reduce flare-ups
Lifestyle and Home Care
-
Bathe with Lukewarm Water: Hot water can dry out the skin and worsen symptoms. Use gentle, fragrance-free cleansers.
-
Moisturize Immediately After Bathing: Lock in moisture by applying a thick emollient while the skin is still damp.
-
Use a Humidifier: Adding moisture to the air can prevent the skin from drying out in low-humidity environments.
-
Wear Soft, Breathable Fabrics: Avoid rough, scratchy clothing like wool that can irritate the skin.
-
Manage Stress: Since stress can trigger eczema, practicing stress-reduction techniques like meditation, yoga, or breathing exercises can be helpful.
