What Is Eczema?

Eczema is a skin ailment that could manifest as dryness, itching, rashes, scaly areas, blisters, and various skin infections due to inflammation of the superficial layer of the skin.

Eczema is simply a range of skin disorders causing inflammation and irritation.

Eczema is an identifiable reaction pattern seen in various skin conditions rather than a single medical illness.

Many people often use the term eczema to refer to the prevalent form of dermatitis, which is atopic dermatitis.

Atopic dermatitis, hay fever, and asthma are constellations of symptoms of immune-related disorders and are referred to as atopic.

Meanwhile, the term dermatitis generally refers to skin inflammation.

Some foods aggravate eczema symptoms, such as nuts and dairy.

Smoke, pollen, and scents are examples of environmental factors which can trigger an eczema flare-up.

Studies show that a quarter of children in the US has this disease condition. Most people grow out of it, whereas others will struggle with it far into adulthood.

Although there is no cure, most patients can control their symptoms by seeking medical help and attempting to avoid irritants.

Eczema is not infectious. Therefore you can’t pass it on to someone else.


Everyone’s eczema brings a different appearance. In addition, individual flare-ups usually do not constantly occur in the exact location.

Eczema is usually constantly itchy. Pruritus is the medical name for itching. The itching might be minimal to severe for many people.

When the itch is intense enough, they scratch it until it bleeds. The “itch-scratch cycle” is what it’s termed, regardless of whatever region of your skin is affected. Itching might occur before the rash appears.

Other symptoms include:

Sensitive and dry skin

Skin discoloration

Inflamed skin

Rough and scaly skin

Skin oozing and crusting


Depending on the severity of eczema, you might have all of the symptoms mentioned above.

However, you may experience occasional flare-ups, or your symptoms may completely disappear.

Eczema can be red in persons with lighter skin, but it can also be ashen, grey, darker brown, or purple in people with darker skin.

The exact cause of eczema is unknown. However, it is believed by many health professionals that eczema occurs as a result of an interplay between genetic and environmental factors.

If a parent has eczema or some other atopic disorder, a child tends to acquire it.

The risk increases if both parents suffer from an atopic condition.

Environmental factors that could trigger a flare-up include:

Irritants – such as detergent, soaps, and shampoos.

Microbes – some fungi, viruses, and bacteria such as staphylococcus aureus. 

Temperature – Extremes of temperature.

Food – Dairy foods, but, egg, etc.

Stress – It is known to make symptoms worse has it is not a direct cause of eczema.

Hormones – When there is a surge in female hormone during pregnancy and menstrual cycle, this could cause worsening of symptoms.


Treatment can include a topical steroid cream and ointments, which helps in relieving inflammatory symptoms and itching.

Other options include oral systemic corticosteroids, antibiotics and an antihistamine.

Often time eczema and dermatitis are used interchangeably.

However, dermatitis is an umbrella term that is used to describe skin inflammation.

Generally, eczema is a kind of dermatitis caused by particular pathogenic microorganisms.

So, while eczemas are all dermatitis, not all dermatitis is eczema.
