eczema complications awareness

Overview

Eczema (also called atopic dermatitis) is a skin condition that makes your skin dry, itchy, and sore. Complications are extra health problems that can happen because of eczema, such as skin infections, sleep problems, and emotional distress. Knowing the warning signs can help you get care early and keep eczema under control.

Eczema is very common, affecting many children and adults. Skin infections and other complications are most likely when eczema is severe or not well controlled.

Anyone with eczema can develop complications. They are more common in young children, older adults, and people with weakened immune systems. People who have large areas of skin affected by eczema are also at higher risk.

Symptoms

Common symptoms

• Dry, scaly, and itchy patches of skin
• Red or inflamed skin (darker on some skin tones)
• Intense scratching, especially at night
• Weeping or crusting when a patch is scratched
• Thickened skin after repeated scratching

Symptoms in children

• More frequent eczema patches in skin folds, such as elbows and knees
• Sleep disruption due to severe itching
• Irritability and constant rubbing against sheets or clothing

Symptoms in older adults

• Very dry, brittle skin
• Eczema patches that appear on the lower legs and backs of the hands
• Slower healing of broken skin, with a higher chance of infection

Causes

Main causes

• The exact cause of eczema isn't fully understood. It involves a problem with the skin barrier, an overactive immune system, and genetics.
• Complications develop when the natural skin barrier is broken by scratching, allowing germs to enter.
• Bacterial infections (usually from a type of bacteria that naturally lives on the skin) are the most common type of skin infection in eczema.
• A more serious viral infection, called eczema herpeticum, can happen if someone with eczema comes into contact with the herpes simplex virus, the same virus that causes cold sores.

Risk factors

• Severe or poorly controlled eczema
• Frequent scratching or dry skin
• Living in hot or cold weather that triggers flare-ups
• Conditions that weaken the immune system
• Recent use of strong medications that suppress the immune system, as prescribed by a doctor

When to see a doctor

See a doctor urgently if:

• You suspect a skin infection (redness, swelling, pus, fever)
• Blisters appear on or near an eczema patch
• Eczema becomes suddenly very painful or spreads rapidly

Book a routine appointment if:

• Your eczema is not improving with moisturizing and gentle skin care
• Itching is interfering with sleep or daily activities
• You need advice on a skincare routine or triggers

Diagnosis

A doctor or nurse will look at your skin and ask about your symptoms, your family history, and what makes the eczema worse. This is usually enough to diagnose eczema and identify possible complications.

Tests that may be done

• A skin swab (gentle cotton wipe) to check for bacteria or viruses if infection is suspected
• Itch-related blood tests if an allergic cause is considered
• Rarely, a small skin sample (biopsy) for unclear cases

What to expect at your appointment

The doctor will ask you about itching, where the rash appears, and how you have been treating it. They may check for signs of infection and, if needed, take a swab. Most of the time, you will leave with a simple care plan.

Treatment

Treatment for eczema complications starts with good skin care and managing the underlying eczema. If an infection is present, your doctor will recommend an appropriate treatment, such as a specific ointment or oral medicine, based on what's causing it. Always use treatments as directed.

Self-care at home

• Apply a moisturizer thickly all over your skin within a few minutes of bathing
• Take lukewarm baths or showers — not hot
• Pat skin dry with a clean towel and avoid rubbing
• Keep fingernails short and try to avoid scratching
• Wear soft, non-irritating fabrics like cotton

Medical treatments

Doctors may prescribe creams or ointments that reduce inflammation and itching. For skin infections, antibiotic or antiviral treatments may be prescribed. For persistent or severe eczema, your doctor may recommend other treatment approaches or refer you to a skin specialist. Never use over-the-counter medicines without asking a pharmacist or doctor.

When is surgery considered?

Surgery is not used to treat eczema or its complications.

Living with this condition

Living with eczema requires a steady routine: daily moisturizing, gentle cleansing, and noticing what triggers your flare-ups. Protecting your skin from scratches and keeping your care products handy makes it easier to stay on top of complications.

Lifestyle tips

• Keep your home environment moderate in temperature, not too hot or dry
• Wash new clothing before wearing to remove residues
• Shower or bathe after heavy sweating and apply moisturizer after
• Avoid known skin irritants like scented soaps and harsh detergents

Diet and exercise

There is no one-size-fits-all diet for eczema. Some people find that certain foods make their skin worse, but this is not common. Exercise is healthy for everyone, and you can stay active by rinsing off sweat and moisturizing afterwards. If you think a food triggers your eczema, talk to your doctor before removing it from your diet.

Mental health and emotional wellbeing

Eczema can feel stressful. Itching, appearance concerns, and sleep loss can affect your mood and confidence. If eczema is making you feel anxious, low, or embarrassed, it is important to talk about this. Mental support is part of treating the whole person. If you are having thoughts of harming yourself, call your local emergency number or a crisis support line immediately.

Prevention

Eczema itself cannot be prevented, but you can reduce the chances of complications. Good daily skin care prevents dryness, and avoiding scratching keeps the skin barrier strong. Early treatment of flare-ups also reduces the risk of infection.

Vaccines

Routine vaccinations are safe and important for most people with eczema. There is one old smallpox vaccine that is not recommended for people with active eczema, but modern vaccines are generally safe. Always tell your vaccination provider about your eczema.

Screening programmes

There is no routine screening test for eczema or its complications in adults or children. Your doctor will check your skin at visits and may do tests if an infection is suspected.

Complications

If left untreated

• Bacterial skin infections that can spread into deeper tissue
• Viral infections like eczema herpeticum, which can be serious
• Long-term sleep problems due to persistent itching
• Depression, anxiety, and reduced quality of life
• In children, poor growth or delays in development in severe cases

Long-term outlook

The outlook for eczema is good, especially when you manage the condition and watch for early signs of complications. Most infections clear quickly with treatment, and many children outgrow eczema or see it become much milder with age. Even if eczema is persistent, comfortable, controlled skin is an achievable goal for most with the right support.
