Discoid eczema is a rare and unique kind of eczema. There are a number of things that makes this eczema kind distinct from all other types of eczema. This includes its prevalence, causes, symptoms, treatment, and prevention.
Discoid eczema, also known as nummular dermatitis, isn’t as common as eczema types like atopic dermatitis, winter eczema, and sebaceous dermatitis. It is one of the few types of eczema that affect only a small percentage of the population. Discoid eczema is common in the elderly, about 60 years of age and above. But it does affect people of all ages.
The causes of discoid eczema are distinct from most eczema types. While most types of eczema are caused by food allergies and exposure to allergens or other skin irritants, discoid eczema is mainly caused by dry skin. Thus, whatever causes your skin to dry up will trigger an discoid eczema outbreak.
The rashes caused by discoid eczema are distinct. They are raised and come in the shape of oval or round coins. Discoid eczema rashes are also itchy. When scratched, they may worsen by spreading to nearby areas. No other type of eczema causes similar-looking rashes.
Since discoid eczema is caused by dry skin, cures for dry skin will in turn treat and prevent its outbreak. Dry skin cures may include:
1. Adequate daily intake of hydrating fluids like water and fruit juices.
2. Use of dry skin products like lotions and skin creams.
3. Vitamin supplementation with “skin vitamins” like vitamins C and E.
4. Wearing sunscreen lotion prior to sun exposure.
5. Switching to a healthier diet.
