RomânăEczema is a chronic inflammatory skin condition that runs in families and leads to dryness, itching, and skin rashes. The most prevalent form is atopic dermatitis. Common areas affected include the folds of the elbows, behind the knees, and the wrists. The primary symptoms include dry, cracked skin, blisters, swelling, and scaly rashes. Exposure to allergens or irritants can worsen these symptoms. While there is no definitive cure, various treatments can help manage and alleviate the discomfort caused by eczema.
What is Eczema?
Eczema is a skin disorder that leads to intense itching, dryness, and the formation of crusty, red, scaly, or thickened skin lesions. It often develops in early childhood but can persist into adulthood or appear later in life. Though it commonly affects areas like the hands, legs, and feet, it can appear anywhere on the body.
This condition weakens the skin’s natural barrier, which is essential for retaining moisture and shielding against external factors. While eczema may cause discomfort and aesthetic concerns, it is not a life-threatening disease. With appropriate management, symptoms can be controlled effectively. Recognizing the signs early and consulting a healthcare professional is crucial for treatment.
What Causes Eczema?
Eczema is triggered by various environmental and genetic factors. These may include exposure to irritating substances like detergents, soaps, shampoos, and bath foams, or environmental conditions such as cold, dry air, dust, pollen, and mold. Other contributing factors include stress, genetic predisposition, and immune system imbalances.
A specific bacterium, Staphylococcus aureus, is also associated with eczema. It replaces the skin’s natural protective bacteria, disrupting the skin barrier and triggering flare-ups.
Common Causes of Eczema:
- Cold and dry weather
- Environmental factors such as humidity
- Allergens (dust, pollen, mold, pet dander)
- Cosmetics and skincare products
- Harsh chemicals like detergents, soaps, and perfumes
- Food allergies
- Exposure to certain metals
- Weakened immune system
- Genetic predisposition
- Air pollution
- Psychological factors such as stress and anxiety
Types of Eczema
Eczema is a broad term encompassing multiple types, each with unique triggers and characteristics.
Common Types of Eczema:
- Atopic dermatitis: A chronic condition influenced by genetic, environmental, and immune system factors.
- Seborrheic dermatitis: Typically occurring in oily areas such as the scalp, face (eyebrows, cheeks, sides of the nose), beard, chest, and ears. This type presents as red, flaky, and crusty skin.
- Asteatotic eczema: Often affecting the elderly, it results from a decline in skin oil levels, leading to extreme dryness and a cracked, porcelain-like appearance. It worsens in cold months.
- Contact eczema: Caused by prolonged exposure to irritants that strip the skin’s protective oils. Common triggers include cosmetics, industrial chemicals, nail polish, perfumes, hair dye, and certain fabrics.
- Nummular eczema: Characterized by coin-shaped, itchy lesions, mainly affecting the arms, legs, and hands. It is chronic and commonly seen in older adults.
- Gravitational eczema: Frequently observed in people with varicose veins or poor blood circulation in the lower legs. It leads to skin hardening, dark patches, and ulcer-like wounds over time.
Symptoms of Eczema
Eczema presents a variety of symptoms, ranging from mild to severe. The most common include:
- Dry, cracked skin
- Itchy, inflamed rashes (which may appear differently based on skin tone)
- Swelling and crust formation
- Skin infections
- Darkening around the eyes
- Pronounced wrinkles on the palms
- Skin sensitivity and irritation
How Eczema Affects the Skin:
- Dry skin: Eczema disrupts the skin’s ability to retain moisture, leading to persistent dryness.
- Intense itching: The body releases chemicals that stimulate nerve endings, triggering excessive itching.
- Rashes: Inflammatory responses in the skin result in widespread red or discolored patches.
- Dry patches: A weakened skin barrier leads to localized areas of dryness and flakiness.
- Cracks in the skin: Loss of moisture causes deep fissures, which may lead to discomfort or infections.
- Swelling: Inflammation and fluid retention result in puffiness and discomfort in affected areas.
How is Eczema Diagnosed?
Eczema is diagnosed through a physical examination and patch testing. A dermatologist may conduct a patch test, where small amounts of allergens are applied to the skin and monitored over 48 to 72 hours.
During this period, patients should avoid water exposure, sweating, or activities that may interfere with results. If redness, blistering, or swelling occurs at the test site, the substance is identified as an eczema trigger.
Treatment Options for Eczema
While eczema cannot be cured, several treatments can alleviate symptoms and reduce flare-ups.
Common Treatments for Eczema:
- Topical corticosteroids (to control inflammation)
- Non-steroidal immunosuppressants
- Wet dressings (to soothe and hydrate affected areas)
- Neutral soaps and barrier creams
- Moisturizers to strengthen the skin barrier
- Eczema gloves and shampoos (for scalp and hand eczema)
How to Manage Eczema on Hands?
The hands are one of the most commonly affected areas due to frequent exposure to irritants. Frequent washing, contact with cleaning agents, and harsh weather conditions contribute to hand eczema.
Treatment for Hand Eczema:
- Use mild, fragrance-free soaps
- Apply moisturizers regularly
- Wear protective gloves while cleaning
How to Treat Scalp Eczema?
Scalp eczema requires topical steroids combined with salicylic acid to manage symptoms. In case of infection, a doctor may prescribe oral antibiotics.
How to Prevent Eczema?
Preventative measures can help minimize eczema outbreaks and improve quality of life.
Tips for Eczema Prevention:
- Avoid scratching the affected area
- Maintain an optimal indoor humidity level
- Ventilate living spaces frequently
- Take lukewarm showers every other day
- Avoid harsh scrubs and hot water
- Use neutral, fragrance-free soaps
- Moisturize immediately after bathing
- Strengthen the immune system
- Keep hands moisturized and wear gloves when cleaning
- Reduce stress and anxiety
- Maintain a balanced diet and proper hydration
- Follow a doctor-recommended eczema diet
