Dermatitis or skin eczema is an inflammation of the skin. There are several forms of dermatitis but all of them have in common symptoms such as itching, pain, inflammation and different parts of the skin may become red, may form blisters and have swollen bumps.
Types of dermatitis:
1. Atopic dermatitis
Atopic dermatitis is one of the most common forms of dermatitis. The condition usually develops during childhood and affects almost 10 to 20% of children whereas it appears in only 1 to 3% of adults. This type of dermatitis causes the skin to itch, scale, swell, and sometimes blister. It usually runs in families and is often associated with allergies, asthma, and stress. Most often the skin affected is in the areas: face, hands, feet, inner elbows, back of the knees. Scratching can cause redness and may also lead to inflammations and infections. Irritants that can make symptoms of atopic dermatitis worse include chemicals, soap detergents, metals and others.
2. Contact dermatitis
Contact dermatitis is more of a skin reaction that occurs on contact with a particular substance such as an irritant that damages physically the skin or an allergen that triggers an immune response leading to skin symptoms. Some of these substances that trigger contact dermatitis include soaps, detergents, dies, nail polish, skin care products, metals, cosmetics, jewellery, perfumes, latex, rubber, certain topical medications and plants such as poison ivy. Finding the exact cause of contact dermatitis can be difficult. Contact dermatitis may be irritant or allergic so the best way to find out is though elimination. Try and stay away from one of the suspected substances, observe your reactions and if they go away try and reintroduce one of these again. Do this until you see which one seems to trigger the skin eruption.
This type of eczema develops usually in areas where people frequently scratch out of habit. It affects areas such as wrists, ankles, back, inside and behind the ear, scalp, genitals. People may scratch affected areas during the day without realizing it. Usually, neurodermatitis causes a skin outbreak that doesn’t get very big however the irritated skin can grow thick and have a wrinkled exterior aspect. Infections may also develop in the irritated areas.
4. Nummular dermatitis
Nummular dermatitis appears under the form of coin-shaped red plaques that are most commonly seen on the legs, hands, arms, and torso. It is more common in men than women. Usually the peak age when it seems to occur mostly is between 55 and 65. Factors that may raise the chance of a break out include a dry environment, having very hot showers, cold air, exposure to chemicals such as formaldehyde and exposure to metals such as nickel. The marks appear most often on the legs, forearms, hips, back of the hands.
5. Stasis dermatitis
Stasis dermatitis is caused by poor circulation of the blood. It is mostly common in people with varicose veins, congestive heart failure, or other conditions. Veins in the lower legs do not return blood efficiently which in return causes pooling of blood and fluid build-up. This leads to irritation, especially round the ankles and in the lower part of the legs. Stasis dermatitis can arise quickly, causing weeping and crusting of the skin. Over time, this type of eczema can cause the skin to develop brown stains.
6. Seborrhoeic dermatitis
This type of dermatitis will be very much detailed and discussed in my blog since I am very familiar with the symptoms, causes, triggers and the way it affects the skin since I dealt with this form of dermatitis myself. Seborrhoeic dermatitis is better known as dandruff. In infants it affects the scalp but in adults it often affects the eyebrows area, the sides of the nose, the area behind the ears, the center of the chest or the groin area. This condition is called cradle cap in infants and is likely to be caused and related to maternal hormonal changes which do affect the sebaceous glands (glands that produce sebum).It also consists of greasy, yellowish, or reddish scaling on the areas of the body mentioned above and it is usually aggravated by stress.
Seborrheic dermatitis causes skin to fall off in flakes. The condition may be due to an overgrowth of a type of yeast that normally lives on the surface of the skin but when the body is in balance, properly nourished and the immune system is working properly the yeast does not attack the skin.
