What Causes Discoid Eczema

The exact cause of discoid eczema, also known as nummular eczema, is unknown, but several factors can contribute to its development, including:

  1. Dry skin: People with dry skin are more prone to develop discoid eczema, as the skin becomes more easily irritated and prone to itching and cracking.
  2. Allergies: Certain allergens, such as food, animal dander, or dust mites, can trigger an eczema flare-up.
  3. Irritants: Exposure to chemicals, such as solvents, detergents, or soaps, can irritate the skin and trigger an eczema flare-up.
  4. Infections: Bacterial or fungal skin infections can trigger an eczema flare-up in some individuals.
  5. Hormonal changes: Hormonal changes, such as those that occur during pregnancy or menopause, can affect the skin and trigger an eczema flare-up.
  6. Stress: Stress can weaken the immune system and trigger an eczema flare-up.
  7. Genetics: Discoid eczema can run in families and may be inherited.

Discoid eczema is not typically life-threatening. However, severe cases can lead to complications such as infection, and can cause significant discomfort, pain, and emotional distress. It’s important to seek prompt treatment for discoid eczema to manage symptoms and prevent the development of any associated complications.

It is also important to work with a healthcare provider to identify the triggers and underlying causes of discoid eczema in order to develop an effective treatment plan.
