eczema when to seek care

Overview

Eczema (also called atopic dermatitis) is a common skin condition that makes the skin dry, itchy, red, and sometimes cracked or weepy. It is not contagious. It often comes and goes in flare-ups, with periods when the skin looks and feels better.

Yes. Eczema is one of the most common skin conditions. Around 1 in 5 children and up to 1 in 10 adults have eczema at some point.

Eczema often begins in infancy or early childhood, but it can first appear at any age. Many children outgrow it. Adults can get eczema too, and it sometimes appears on the hands, eyelids, or in skin folds.

Symptoms

Common symptoms

• Itching, which can be mild to intense
• Dry, sensitive patches of skin
• Red or darkened patches, depending on your skin tone
• Rough, scaly, or thickened skin
• Small bumps that may weep or ooze when scratched
• Crusting or flaking

Symptoms in children

• Eczema often appears on the face, scalp, elbows, and knees in young children
• Itching can disturb sleep, causing tiredness in the daytime
• Children may rub against bedding or furniture to relieve the itch
• Patches may ooze more often than they do in adults

Symptoms in older adults

• Eczema often affects the hands, eyelids, or the back of the neck
• Skin may be very dry and thickened from years of scratching
• Itching can be severe and disrupt sleep
• Older skin is more fragile, so eczema may crack and bleed more easily

Causes

Main causes

• A problem with the skin barrier, which lets moisture escape and lets irritants in
• An overactive immune response that causes inflammation in the skin
• Genetics — eczema often runs in families
• Triggers such as harsh soaps, dry air, sweat, wool, stress, and sometimes allergens

Risk factors

• Having a personal or family history of eczema, asthma, or hay fever
• Living in a cold, dry climate
• Having very dry or sensitive skin
• Jobs or hobbies that involve frequent hand washing or contact with chemicals

When to see a doctor

See a doctor urgently if:

• Eczema suddenly becomes much worse or very painful
• You see signs of infection: oozing, yellow crusts, red streaks, or a bad smell
• Eczema is not improving with moisturizers and trigger avoidance
• The itch is so bad that you or your child cannot sleep several nights in a row

Book a routine appointment if:

• You or your child has eczema symptoms for the first time
• You need a clear plan for managing daily flare-ups
• Flare-ups happen often and interfere with work, school, or social life
• Your skin keeps cracking, bleeding, or feels uncomfortable despite regular care

Diagnosis

A doctor or nurse will usually diagnose eczema by looking at your skin and asking about your symptoms, sleep, and any family history of eczema, asthma, or allergies. In most cases, no special test is needed.

Tests that may be done

• A skin examination in a well-lit room
• Questions about when the rash started and what makes it worse
• Sometimes a patch test to check for contact allergies
• Sometimes a skin swab to check for infection, especially if the eczema is weeping or crusted

What to expect at your appointment

You'll be asked how long you've had the rash, how itchy it is, and whether you have any known triggers. The doctor may look at several areas of skin and check for signs of infection. Then they will help you create a skincare routine and talk about treatment options.

Treatment

Treatment for eczema focuses on repairing the skin barrier, reducing itch and inflammation, and preventing flare-ups. Eczema is not usually cured, but it can be very well controlled with daily care and the right treatments for flare-ups.

Self-care at home

• Moisturize your skin at least twice a day, especially right after bathing or washing your hands
• Use lukewarm water for bathing or showering — not hot water
• Pat your skin dry gently with a soft towel instead of rubbing
• Choose fragrance-free, gentle cleansers and moisturizers
• Avoid scratchy fabrics like wool; wear soft cotton next to your skin
• Keep nails short and consider cotton gloves at night to reduce scratching damage

Medical treatments

If self-care is not enough, a doctor may recommend prescription treatments to reduce inflammation. These are usually applied to the skin, such as topical steroids or non-steroid creams. For severe eczema, doctors may consider light therapy, tablets, or other medicines that work throughout the body. Always follow your doctor's instructions and never use someone else's prescription medicine.

When is surgery considered?

Surgery is not used to treat eczema itself. Rarely, a small procedure may be needed for a complication like a skin abscess, but this is uncommon.

Living with this condition

Eczema needs daily attention, not just when it flares. A simple routine — moisturize regularly, avoid known triggers, and treat early signs of a flare — can make a big difference.

Lifestyle tips

• Wear soft, breathable clothing and avoid tight or scratchy fabrics
• Use fragrance-free laundry detergent and rinse clothes well
• Keep your bedroom cool and use a humidifier in dry weather
• Find healthy ways to manage stress, such as breathing exercises, gentle exercise, or talking to someone
• Avoid long, hot showers or baths that dry out the skin

Diet and exercise

Regular exercise is good for your health, but sweat can trigger eczema. Shower soon after exercise and reapply moisturizer. There is no single 'eczema diet.' Unless a specific food clearly triggers your flare-ups, restrictive diets are not usually helpful. Talk to your doctor before cutting out foods, especially for children.

Mental health and emotional wellbeing

Eczema can feel frustrating, embarrassing, or stressful. Constant itching can disrupt sleep and affect your mood. It's normal to feel worried or down at times. If these feelings are heavy or lasting, speak to your doctor — getting support is a sign of strength, not weakness.

Prevention

Eczema itself cannot always be prevented, but flare-ups can be reduced. Regular moisturizing, gentle skincare, and avoiding your personal triggers are the most effective ways to keep eczema calm.

Vaccines

There is no vaccine for eczema. It is still important to keep routine vaccinations up to date, especially if you have frequent skin infections.

Screening programmes

There is no routine screening test for eczema. It is usually diagnosed when symptoms appear.

Complications

If left untreated

• Skin infections, such as staphylococcal infections, that can make eczema worse
• Sleep problems and daytime tiredness
• Thickened, leathery skin from long-term scratching
• Rarely, eczema herpeticum — a serious viral skin infection that needs urgent medical care

Long-term outlook

With the right care, most people with eczema live full, active lives. Flare-ups usually settle, many children grow out of it, and treatments continue to improve. Even when eczema is stubborn, a good care plan can bring real relief. There is every reason to be hopeful.
