Comprehensive Guide to Eczema: Types, Causes, Symptoms, and Treatment Strategies

Eczema, also called dermatitis, is a prevalent skin disorder impacting the outermost skin layer, the epidermis. The skin consists of three layers: epidermis, dermis, and subcutaneous tissue. Characterized by inflammation, dryness, and intense itching, eczema results in rough, red, or blistered patches. It affects individuals from infancy to adulthood and can be recurrent or chronic. The condition makes the skin vulnerable to irritation, infections, and barrier impairment.

The spread of eczema through contact is not possible as it is non-contagious. Its precise cause remains unidentified, though genetic predisposition and environmental factors are influential. Allergic responses activate skin immune cells, triggering flare-ups. Common variants include atopic dermatitis, contact eczema, dyshidrotic eczema, hand eczema, neurodermatitis, nummular eczema, seborrheic dermatitis, and stasis dermatitis. Atopic dermatitis is the most common and severe form. All types cause itching, redness, and blister formation, with symptoms varying among individuals.

Causes of Eczema

Genetic predisposition, especially with a family history of allergies or asthma, increases susceptibility. Skin barrier issues can lead to dryness and infections.

The exact cause remains unclear, but an overactive immune response to environmental allergens and irritants is suspected.

Triggers include stress, aggressive skincare products, temperature extremes, and rough textiles.

Signs and Symptoms

In infants, symptoms involve dry, itchy patches on the scalp and cheeks, sometimes with oozing or crusts. Persistent scratching may lead to infections and inflammation.

In adults, eczema manifests as rashes on elbows, knees, neck, and other areas, often resulting in thick, flaky skin and ongoing itchiness. Common locations include wrists, hands, legs, and areas around the eyes.

The affected skin tends to be dry, flaky, erythematous, or darker, with pigmentation alterations over time.

How to Manage Eczema

While there is no cure, treatments aim to control symptoms and prevent flare-ups.

Home management involves wearing soft fabrics, applying gentle moisturizers, avoiding harsh soaps, taking lukewarm baths, and keeping nails trimmed to minimize scratching.

Medical options include topical steroids, calcineurin inhibitors, and oral medications to reduce inflammation and itching.

Phototherapy, which uses controlled ultraviolet light, may be recommended in moderate cases.

The severity of eczema varies based on genetic and environmental factors. Awareness of symptoms and triggers helps in effective management. Consulting healthcare professionals and adopting proper skincare routines are key for controlling this chronic skin condition.
