Is eczema linked to food allergies?

Is eczema linked to food allergies? | Annabel Karmel

Many parents want to know is eczema linked to food allergies?

Eczema, also known as ‘atopic eczema’ or ‘atopic dermatitis’, is a skin condition causing inflammation and intense irritation. Eczema symptoms tend to be caused by dry skin. Scratching is hard to avoid since the main distressing symptom of eczema is unbearable itching but once the skin gets broken and cracked, infections can set in, causing even more discomfort.

This skin condition can affect any age range and it is thought to be caused by a defect in the skin barrier that makes it more susceptible to inflammation and allows allergens and bacteria to make contact with the immune system. Eczema can affect quality of life significantly and may also affect sleep patterns. Whilst this can make you irritable and frustrated, good management can help alleviate these problems. This skin condition is well understood and dermatologists (skin doctors) have developed effective skin treatment regimens to control and manage the symptoms. It can take some time to find the most suitable therapy for each individual, often causing embarrassment and daily frustration with the symptoms in the meantime. Many people do not understand that eczema is neither infectious nor contagious.

Generally, GPs can diagnose eczema and differentiate whether it is eczema or another skin condition. Seasons of the year (for example, in winter), or even emotional responses (such as stress), may cause eczema to worsen. However, a large number of eczema sufferers are not able to link a cause to their symptoms. It is essential that any known triggers are avoided and sometimes keeping a ‘trigger symptom’ diary at home may help you to realise what might be causing flares.


Eczema can be treated in a number of ways, emollients, wet wraps, topical steroid creams and calcineurin inhibitors can all be used.

Emollient Lotions

Emollient lotions and creams are prescribed for eczema and dry skin, and are, in their simplest form, mixtures of oil and water. Some emollients may also contain slight amounts of antibacterial chemicals (to avoid infection in broken skin), or steroids (to reduce inflammation). Emollient products range in their consistency, from being runny lotions to thick creams, and while they can be a very cooling and soothing treatment for eczema, the stickiness of the thicker products can sometimes make them a source of annoyance. It is important to find a product that is suitable for you.


It is sometimes necessary to apply topical corticosteroids (e.g. hydrocortisone), as these reduce inflammation in the skin. Many people worry when steroids are mentioned as a treatment option because of stories they may have heard in the media, particularly related to anabolic steroid abuse in sports. These, however, are not the same steroids that are used as medical treatments and, when used as directed by a physician, steroids have an important role to play in treating a range of ailments, including eczema. Topical steroids are safe to use but it is important to always follow the instructions provided, making sure you understand which areas you apply the cream to and exactly how much. If you have any questions, then ask your doctor or nurse for further advice and information.

Wet Wraps

Sometimes, special pyjama-like garments (known as ‘wet wraps’) that are used for children, may also help certain areas of the  body that have not responded to the usual topical application of emollients and steroids. Wet wraps can also be useful if you suffer from itch at night and cannot sleep, allowing you to have a better quality of sleep during times when the eczema is particularly bad. There are various ways of applying these garments and your nurse or doctor will be able to demonstrate the best way of application.
