What is dermatitis?
Do any area of your body itch and the more you scratch, the more it itches? Have you noticed any rash on your skin? In these cases, you are likely to have dermatitis.
Dermatitis is a skin condition that manifests itself as rashes and reddening of the skin, in addition to intense itching. It should not be confused with other skin conditions, such as psoriasis.
Dermatitis rashes can lead to suppurating crusts, depending on the type of dermatitis and the severity of the case. It is not a contagious disease. However, it can cause discomfort to the sufferer. Although dermatitis can have different causes and symptoms, it usually shows in the form of inflamed, reddened and itchy skin.
Let’s look at the types of existing dermatitis.
Types of dermatitis
Among the types of dermatitis include:
It is a widespread disease that has a hereditary character and affects millions of people. The atopic dermatitis is usually chronic or long-term and is considered as a particular type of allergy or skin sensitivity. The triad of atopic dermatitis includes asthma, allergies such as hay fever and eczema.
Atopic dermatitis usually starts in early infancy and is characterized by pruritus, eczematous lesions, dry and tight skin, lichenification, or increased skin thickness and skin tags.
In many cases, dermatitis goes through periods that worsen called outbreaks or exacerbations that are then followed by periods where the skin improves or may even disappear. Some older children tend to grow quite a bit even though their skin is still drier and easily irritated.
The contact dermatitis is a localized rash caused by skin contact with a substance that is foreign to the body. The substances that commonly cause contact dermatitis are usually metals, cleaning products, plant sap, cosmetics, industrial chemicals, latex additives and so on.
Among the most common symptoms of contact dermatitis are:
- Redness and swelling of the exposed area
- The sensation of heat in the area
- Eruption or skin lesion in said area (eruption, or blisters, or vesicles may occur)
Also called as gravitational dermatitis, this occurs in the area of the legs due to stasis or poor return circulation.
The seborrheic dermatitis is a skin disorder that primarily affects the scalp causing itching, peeling, redness, and dandruff. In infants, seborrheic dermatitis is called cradle. Seborrheic dermatitis can also affect areas of the face, back or upper chest.
It is not contagious nor it is a sign of poor personal hygiene.
It is a type of dermatitis caused by excessive itching and scratching. It usually begins with an area of the skin where there is itching, or sometimes a person scratches an area by habit, this circle of itching and scratching can cause the affected skin to thicken and to appear harder.
