Understanding Eczema: Causes, Symptoms, and Treatment Options

Eczema is a common skin condition that causes itchiness, rashes, dry patches, and sometimes infection. It is a type of dermatitis, which refers to a group of conditions that can cause inflammation or irritation of the skin. The most common form of eczema is called atopic dermatitis or atopic eczema. "Atopic" means that you are more likely to develop allergic conditions such as asthma and hay fever.

Over 31 million Americans have eczema, and most people can manage their symptoms by getting proper treatment and avoiding irritants that can affect the skin upon contact. Periods when symptoms are at their worst are called flare-ups, which can last for days or even weeks.

Eczema Symptoms

Eczema looks different for everyone, and flare-ups may not always occur in the same area. The appearance of an eczema rash will vary depending on your skin color. Regardless of which part of your skin is affected, eczema is almost always itchy. The itching may start even before the rash appears. Your skin may also be:

Red
Dry and cracked
Swollen with a rash (color varies depending on skin tone)
Bumpy (on brown or Black skin)
Thick and leathery
Oozing and crusting
Raw from scratching

Symptoms can vary depending on age. In infants, the itchy rash can cause oozing and crusting, mainly on the face and scalp, but also on the arms, legs, back, and chest. Children and teens usually have the rash in the bends of their elbows, behind their knees, or on their necks, wrists, or ankles. In adults, the rash commonly appears on the face, backs of the knees, wrists, hands, or feet.

When to See Your Doctor

Contact your doctor right away if you have been taking steps to manage your symptoms but notice signs of infection (such as fever, redness, warmth, pus, or blisters), if your eczema suddenly changes or gets worse, or if treatments are not working.

Types of Eczema

There are several types of eczema, including:

Atopic dermatitis: The most common form, often starting in childhood.
Contact dermatitis: Caused by contact with irritants or allergens.
Dyshidrotic eczema: Characterized by tiny blisters on the palms, soles, and sides of fingers.
Neurodermatitis: Causes intensely itchy patches, often triggered by stress or anxiety.
Nummular eczema: Appears as coin-shaped patches, often after a skin injury.
Seborrheic dermatitis: Affects areas with many oil glands, such as the scalp (dandruff).
Stasis dermatitis: Occurs in people with poor blood flow, usually in the lower legs.

Eczema Causes and Risk Factors

The exact causes of eczema are not fully understood, but factors that may contribute include an overactive immune response, problems in the skin's barrier, stress, genes, and environmental triggers such as pollen, cold and damp or hot and humid weather, and exposure to irritants or allergens.

Risk factors for developing eczema include having a family history of eczema or other allergies, living in certain climates, and being exposed to certain substances. Age can also play a role, with eczema being more common in children under 5 and adults in their 20s or over 50.

Eczema Flare-Ups and Prevention

Eczema flare-ups occur when the immune system responds to a trigger, causing inflammation and leading to itchy, painful symptoms. Common triggers include stress, environmental factors, allergens, and irritants such as rough fabrics, harsh soaps, or certain foods.

To help prevent flare-ups, you can:

Moisturize your skin often
Avoid sudden changes in temperature or humidity
Manage stress and take time to relax
Avoid scratchy materials and harsh soaps or detergents
Identify and avoid food triggers
Use a humidifier in rooms where you spend the most time

For infants at higher risk of eczema due to family history, breastfeeding exclusively for the first 3-6 months and protecting them from potential allergens can help reduce the likelihood of developing the condition.

Eczema and Mental Health

There is a strong link between eczema and emotional well-being. While stress, anxiety, and depression do not cause eczema, they can trigger a physical reaction that includes inflammation, worsening flare-ups. Conversely, having eczema can increase the risk of mental health issues. One study found that over 30% of adults with eczema also have depression, anxiety, or both.

To manage mental health when living with eczema, try techniques such as meditation, spending time outdoors, and exercise. If you experience symptoms of depression for 2 weeks or more, consult your doctor. They may recommend joining a support group or starting therapy with a mental health professional.

Eczema Diagnosis and Treatment

Eczema is typically diagnosed through a physical examination of the skin and a review of your medical history. Your doctor may also order allergy tests to identify potential irritants or triggers, especially in children.

Treatment for eczema aims to reduce itching and prevent infection. Options may include:

Moisturizing creams and ointments to hydrate the skin and reduce inflammation
Topical corticosteroids to ease inflammation
Oral antibiotics if the area becomes infected
Topical immunomodulators (TIMs) for mild to moderate eczema
Biologic drugs for moderate to severe cases
Light therapy (phototherapy)
Stress management techniques
Wet wrap therapy

In addition to medical treatments, home remedies such as moisturizing regularly, using gentle cleansers, taking lukewarm baths with colloidal oatmeal, and applying cold compresses can help manage symptoms.

Living with Eczema

Living with eczema can be challenging, but there are ways to manage the condition and reduce flare-ups. Tips for managing eczema in daily life include:

Identifying and avoiding triggers
Adopting a balanced, anti-inflammatory diet
Engaging in low-impact exercises and staying hydrated
Managing stress through relaxation techniques
Moisturizing regularly and using gentle, fragrance-free products

While there is currently no cure for eczema, with proper treatment and management, most people can effectively control their symptoms and enjoy a good quality of life. If your eczema worsens or does not respond to treatment, consult your doctor or dermatologist for further guidance.
