Genetic inheritance plays a major role in most forms of eczema.

Atopic dermatitis is an inherited oversensitivity of the immune system. Genes play a role in allergies too, though it usually takes prolonged exposure to a given allergen before it becomes a nuisance.
Of course, there are some chemicals that will irritate any skin. Harsh irritants can give anyone a temporary bout of contact dermatitis. Contact dermatitis may be caused by irritants or allergens.

Stasis dermatitis is caused by poor circulation in the lower extremities. Fluid builds up in the capillaries due to raised blood pressure. This causes inflammation of the skin.

Atopic dermatitis appears as red, itchy, dry skin. It tends to first appear in childhood, and may disappear completely before adulthood. It most often affects the area behind the knees and around the elbows, as well as the face. In infants, it often appears on the chest, face, scalp, and neck. Atopic people who contract the herpes simplex virus can be struck by eczema herpeticum, a serious secondary infection of the inflamed skin that causes a worsened rash and fever.

Contact dermatitis often causes a dry and intensely itchy, red rash. Depending on the trigger to the reaction, the rash may actually be painful, forming blisters that ooze before crusting over. Other reactions caused by irritants cause swelling at the affected area. The area involved may be a clue what allergen or irritant is responsible. The worst forms of allergic contact dermatitis, such as severe latex reactions, can be associated with the potentially fatal allergic reaction called anaphylaxis, which is a body-wide response to the allergen.

Dyshidrotic eczema can cause blisters on the palms of the hands, sides of the fingers, and soles of the feet. The skin will feel itchy or you may feel a burning sensation, and it can crack or peel.

Nummular eczema appears as itchy, red, coin-shaped areas with discharge on the limbs and torso.

Stasis dermatitis appears as inflamed, scaly skin around the lower legs and ankles. Over time, it may turn dark brown.

To make a diagnosis of eczema, your doctor will examine your skin, and ask you questions about your symptoms. If you get inflamed skin, it's important to tell your doctor about any allergies you have and any unfamiliar substances you have recently come in contact with.

Looking at the skin itself will often allow a physician to distinguish particular types of eczema, although sometimes a skin biopsy or other testing is necessary.

Your doctor will recommend a treatment plan for your eczema that will take into consideration the type of eczema you have, the severity of the eczema, as well as other factors. For most people, a combination of therapies is needed to manage eczema.

Treatment options for most types of eczema can include moisturizers and topical corticosteroids (e.g., betamethasone*, desonide, hydrocortisone, prednicarbate). Topical calcineurin inhibitors (e.g., tacrolimus, pimecrolimus) may also be used to treat atopic dermatitis. The most important step in both treating and preventing eczema flare-ups is frequent moisturizing.

For some people with more severe eczema, oral corticosteroids may be needed to control symptoms. For older adults, ultraviolet (UV) radiation is sometimes used, but the skin cancer risk makes this unsuitable for younger people. Antihistamines that cause drowsiness may be recommended for some types of eczema to help with itching and sleep. When skin infections occur, topical or oral antibiotics may be prescribed.

Stasis dermatitis can be helped by keeping in good physical shape so that blood flows freely through the legs. Support stockings can also assist in pumping the blood up out of the leg. Elevating your legs also increases circulation.

Susceptibility to most forms of eczema is genetic and unavoidable. Knowing what allergens and irritants to avoid can help you get through life without being too inconvenienced by eczema.

Other tips to help you deal with eczema include:

• Bathe in cool or tepid water with gentle soap. Minimize the use of soap when possible.
• Use moisturizers immediately after you bathe to keep the moisture locked in. Avoid moisturizers with perfumes, as they may worsen the condition.
• Avoid scratching affected areas. Some people wear cotton gloves at night to prevent scratching in their sleep.
• Keep your fingernails short.
• Don't let sweat stay on your skin.
• Avoid clothes that don't let the skin breathe.
