Eczema is chronic skin condition, but in most cases it can be controlled with treatment. Prognosis is affected by several factors such as the type of eczema and response to treatment.
Prognosis of eczema
Atopic eczema: This type of eczema occurs primarily in children. In most cases it improves by the age of 5 years, although exacerbations can occur throughout adolescence and into adulthood. Some factors associated with poor prognosis include patients with severe disease, early age of onset, family history, and associated rhinitis or asthma. However, even in these patients, the symptoms usually resolve completely by the time they age 30 years. Some children may experience long-term psychological injury because of challenges of living with a visible, sometimes disabling, skin disease during their formative years.
Contact eczema: The prognosis of people with this eczema is good if the substance to which the person is sensitive is removed and not exposed to it again. In these cases the rash may heal on its own in less than three weeks. If treated properly the symptoms may go away sooner. However if you are exposed to the substance again, you will develop skin rash as your immune system will always respond to the chemical to which you were allergic.
If you are allergic to a substance such as nickel and balsam of Peru, dietary changes may be necessary to prevent dietary exposure. Some factors associated with poor prognosis include occupation-associated contact dermatitis, delayed treatment, presence of chronic dermatitis, allergy to substances such as nickel or chromium, and a history of atopic dermatitis.
Irritant contact eczema: Prognosis is good for nonatopic people (with irritant contact eczema) who are diagnosed in the early stages and managed promptly. Atopic people may remain extremely susceptible to various substances (used at home or at work). They may find working even in common occupations (such as nursing, hairdressing) cause too much skin inflammation to continue with their careers. Some people may need to restrict their daily activities while living at home and at work because of severe irritant contact dermatitis.
Seborrheic eczema: This is a chronic (life-long) condition that is controlled with treatment in most people. However you may have repeated episodes of flare-up after extended inactive periods. It tends to improve in the summer, especially after outdoor activities. As seborrheic dermatitis does not usually cause any serious problems, the prognosis is generally considered good.
Discoid eczema: Most people with discoid eczema tend to have chronic and recurrent disease. Avoiding factors that cause relapse can help yourself in managing the disease easily.
