Causes And Symptoms Of Types Of Eczema
There are several types of eczema. The types of eczema vary by what triggers the rash and the appearance of symptoms of the rash.
Atopic dermatitis, often referred to as eczema, is the most common type of that. Atopic dermatitis is also called dermatitis or atopic eczema. The cause of atopic dermatitis is thought to be genetic.
An itchy, inflamed rash is a common symptom of atopic dermatitis. The rash may also be dry and flaky or weeping. Of the young children who develop atopic dermatitis, about half will continue to have symptoms into adulthood.
Contact dermatitis is a type of eczema that is attributed to touching or being exposed to an allergen. If the skin of a person with an oversensitive immune system comes in contact with an allergen, their skin becomes irritated.
The rash from contact dermatitis can be itchy, red, and dry. In more severe reactions, blisters may form and break leaving a scaly rash. Some examples of the numerous allergens that can cause contact dermatitis include soaps, shampoos, metals, and bleaches.
Advanced age makes some people susceptible to particular types of eczema. One type of eczema that most commonly affects people over the age of forty is stasis eczema. This type of eczema is caused by poor circulation.
Nummular eczema, also called discoid eczema or nummular dermatitis, is a type of eczema that causes blisters in small coin-shaped patches. Though the cause of this type of eczema is not completely understood, it is thought to be caused by hypersensitivity to some metals and medications.
The elderly are prone to developing a type of eczema called asteatotic eczema. If an elderly person has dry skin, asteatotic eczema can develop and cause painful cracks in the dry skin.
Seborrheic dermatitis is a type of eczema that commonly affects the scalp but may also affect the face and other parts of the body. Cradle cap and dandruff are forms of seborrheic dermatitis.
Dyshidrotic eczema causes a severe eczema rash with blisters, intense itchiness, and deep, painful cracks. The exact cause of dyshidrotic eczema is not well understood, but it most often occurs to people who have personal or family medical histories of asthma, eczema, or hay fever.
Neurodermatitis is a type of eczema caused by irritation of the nerves. This type of eczema causes intense, persistent itchiness.
