Comprehensive Overview of Eczema: Causes, Symptoms, and Treatment Strategies

Dermatitis, commonly called eczema, results in skin inflammation and irritation. Among various forms, atopic dermatitis is the most widespread, impacting over 18 million adults nationwide. It manifests as a red, itchy rash often appearing on the limbs, face, and sensitive regions. Infants are especially vulnerable within their first six months, though some individuals experience flare-ups into adulthood.

While a cure is unavailable, symptoms can be managed effectively.

Causes of Eczema
The precise cause remains uncertain, but atopic dermatitis is closely linked to allergies such as hay fever and asthma. Genetic factors play a critical role; having relatives with these conditions increases risk. A mutation affecting filaggrin, a protein essential for skin barrier integrity, can lead to dryness and susceptibility to infections. External triggers that provoke immune reactions can worsen symptoms.

Signs of eczema include:

Severe itching

Dry, flaky skin

Rashes on limbs and face

Open or crusty sores

Redness and cracking, especially behind ears

Secondary infections may develop, producing pus-filled boils or yellow crusts. Multiple eczema types may coexist, complicating diagnosis.

Common Triggers
Factors that can activate symptoms involve:

Chemicals: Detergents, disinfectants, shampoos, and metals can provoke reactions.

Infections: Bacterial, viral, or fungal infections may cause flare-ups.

Stress: Mental stress tends to worsen symptoms.

Weather: Dry or variable climates heighten dryness and irritation.

Allergens: Pollen, pet dander, and mold may trigger outbreaks.

Hormonal Changes: Fluctuations in hormones can lead to flare-ups.

Effective Management and Treatment
Managing eczema involves avoiding known triggers and maintaining skin health. Key approaches include:

Consistent bathing and moisturizing routines

Following prescribed medication guidelines

Avoiding scratching and skin irritation

Reducing airborne allergens in the home

Support groups offer emotional support and practical advice. Treatment options range from topical over-the-counter creams to phototherapy. Severe cases might require immunosuppressive medications like DUPIXENT®, the first FDA-approved biologic for moderate to severe eczema in individuals over 12. Proper care and medical consultation are essential for effective management.
