Overview
Eczema, also called atopic dermatitis, is a chronic skin condition that makes your skin red, itchy, and inflamed. It's one of the most common skin problems in the United States. The condition often starts in childhood but can develop at any age.
Eczema affects people differently. Some have small patches of dry skin, while others experience widespread inflammation. The condition tends to come and go in cycles, with periods of flare-ups followed by times when symptoms improve.
More than 31 million Americans live with some form of eczema. While it's not contagious, eczema can significantly impact quality of life. The good news is that with proper care, most people can manage their symptoms effectively and live comfortably.
Symptoms & Signs
Eczema symptoms can vary from person to person and may change over time. The condition often appears in cycles, with periods of active symptoms followed by calmer phases.
Primary Symptoms
Red or brownish patches of skin that feel rough or scaly
Intense itching that may worsen at night or during stress
Small raised bumps that may leak fluid when scratched
Thick, cracked, or dry skin that may feel tight or painful
Raw, sensitive areas from scratching that may become infected
When to Seek Care
You should contact a healthcare provider if your eczema symptoms suddenly worsen or don't improve with over-the-counter treatments. Signs of infection include increased redness, warmth, pus, or red streaks extending from the affected area.
When to Seek Immediate Care
Seek emergency care if you develop signs of serious infection, such as fever, widespread rash with blisters, or severe pain that interferes with daily activities.
Causes & Risk Factors
Age
Most common in infants and children, but can develop at any age
Genetics
Having family members with eczema, asthma, or allergies increases risk
Lifestyle
Exposure to harsh soaps, stress, and certain fabrics can trigger flares
Other Conditions
People with asthma, hay fever, or food allergies are more likely to develop eczema
Diagnosis
Medical History & Physical Examination
Your healthcare provider will examine your skin and ask about your symptoms, family history, and potential triggers. They'll look at the pattern and appearance of your rash to distinguish eczema from other skin conditions. The provider may ask about when symptoms started, what makes them better or worse, and any treatments you've tried.
Diagnostic Testing
Patch testing to identify specific allergens that trigger your eczema
Blood tests to check for elevated levels of immunoglobulin E (IgE) antibodies
Skin biopsy in rare cases to rule out other skin conditions that look similar to eczema
Treatment Options
The goal of eczema treatment is to reduce inflammation, relieve itching, and prevent future flare-ups. Treatment plans are tailored to each person based on age, severity, and triggers.
Conservative Treatments
Moisturizers and emollients applied daily to maintain skin barrier function
Topical corticosteroids to reduce inflammation during active flare-ups
Antihistamines to help control itching, especially at night
Gentle skincare products free from fragrances and harsh chemicals
Advanced Treatments
Prescription topical medications like calcineurin inhibitors when steroids aren't suitable
Phototherapy using controlled UV light for widespread or stubborn eczema
Biologic medications for severe cases that don't respond to other treatments
Wet wrap therapy to help healing and reduce the need for stronger medications
Living with the Condition
Daily Management Strategies
Keep your skin moisturized by applying fragrance-free lotions or creams at least twice daily. Take lukewarm baths or showers for no more than 10-15 minutes, and gently pat your skin dry instead of rubbing. Identify and avoid your personal triggers, which might include certain foods, fabrics, or environmental factors. Managing stress through relaxation techniques can also help reduce flare-ups.
Exercise & Movement
Regular exercise is beneficial for overall health, but choose activities carefully. Swimming in chlorinated pools may irritate sensitive skin, so rinse off immediately afterward. Wear breathable, loose-fitting clothes made from soft fabrics like cotton. Avoid activities that cause excessive sweating in hot, humid conditions.
Prevention
Use gentle, fragrance-free soaps and moisturizers daily to maintain your skin barrier
Wear soft, breathable fabrics like cotton and avoid wool or synthetic materials that may irritate
Keep your home's humidity between 30-50% using a humidifier during dry seasons
Manage stress through regular exercise, adequate sleep, and relaxation techniques since stress can trigger flare-ups
Frequently Asked Questions
No, eczema is not contagious. You cannot catch it from someone else or spread it to others through contact. It's an inflammatory skin condition caused by genetic and environmental factors, not by bacteria or viruses.
Yes, certain foods can trigger eczema flare-ups in some people. Common triggers include dairy, eggs, nuts, soy, and wheat. However, food triggers vary greatly between individuals, so it's important to work with a healthcare provider to identify your specific triggers.
Many children do see improvement as they get older. About half of children with eczema will have clearer skin by their teenage years. However, some people continue to have eczema into adulthood, though it may become less severe over time.
Yes, stress is a well-known trigger for eczema flare-ups. When you're stressed, your body releases hormones that can increase inflammation and make itching worse. Learning stress management techniques can help reduce the frequency and severity of flare-ups.
Research suggests eczema may have autoimmune components, though it's not classified as a traditional autoimmune disease. People with eczema often have other allergic conditions like asthma or hay fever, suggesting shared underlying mechanisms.
