Eczema

3-minute read

Eczema causes red, itchy and dry skin, which can be very irritating. But there are many ways to manage eczema and with your doctor’s help, you will likely find out what works for you.

What is eczema?

Eczema is a common skin condition that affects both children and adults. It’s also known as atopic eczema, atopic dermatitis and allergic eczema.

Nobody knows exactly what causes eczema, but it can run in families. Many people with eczema also have other allergic conditions, including hay fever and asthma.

People with eczema find it hard to keep the moisture in their skin, so it becomes dry and easily irritated. This causes chemicals to be released, which worsens the irritation and makes you want to scratch. But scratching only makes your skin more itchy and so the cycle repeats itself. This can be very frustrating.

What triggers eczema?

There are many things, known as triggers, that can make eczema symptoms worse, including:

  • dry skin
  • scratching the affected area
  • viral or bacterial infections
  • chemicals from swimming pools
  • sand, especially from sandpits
  • contact with some types of carpet or grass
  • allergens that you can breathe in, such as pollen
  • artificial colours and preservatives
  • perfumes, soap and chemicals
  • woollen or synthetic fabrics
  • heat or very hot rooms
  • stress.

Not all of these things will trigger a person’s eczema. It varies from person to person.

Symptoms of eczema

If you have eczema, you’ll have areas of red, dry, itchy skin, most commonly found in the creases of your elbows, wrists, neck and behind the knees.

Use healthdirect's online Symptom Checker to find out whether you might have eczema.

Diagnosis of eczema

Your doctor will be able to diagnose your eczema by talking to you and examining you. They might also request allergy tests to help with the diagnosis and inform your treatment. Your doctor will help you discover what triggers your eczema.

Treatment of eczema

While there is no cure, eczema is quite treatable. Here are some ways to manage your eczema:

  • Protect your skin by applying moisturiser every day. Some people with severe eczema might need wet dressings, which cool, protect and rehydrate the skin.
  • Treat flare-ups by using ointments or creams prescribed by your doctor.
  • Control itching by using antihistamines, a cold compress for the affected area and trying not to scratch.
  • Control and prevent infection by keeping your house clean and using antibiotics to treat infection if prescribed by your doctor.

Some dermatologists might also use ultraviolet light (PUVA) to reduce inflammation.

Many people find eczema improves as they get older.

There is no evidence that probiotics and evening primrose oil are effective in treating eczema.

Once you know what triggers your eczema, your doctor may be able to help you develop an eczema action plan. This is a personal guide and checklist for how to manage your eczema and prevent it from flaring up.
