Eczema | All You Need to Know About Eczema

What about risk factors and causes of eczema?

We don’t know exactly the causes of eczema, but researchers think that a combination of genes and triggers has a role in getting the disease. You may be at risk of the disease if one or both of your parents have the disease. The interaction between the surrounding environment and your genes may contribute to eczema.

When an allergen outside or inside your body irritates your immune system, it results in inflammation on your skin surface. The deficiency of a protein called “filaggrin” that maintains moisture in your skin leads to itchy and dry skin.

Environmental irritants that cause allergic reactions and eczema include:

    • Prolonged exposure to dry air, extreme heat, or cold
    • Contact with some types of detergents as soap, shampoo, bubble bath, body wash, and cleansers
    • Cocamidopropyl betaine used in shampoo
    • Fabric softeners with chemical additives
    • Contact with wool or polyester in clothing and sheets
    • Natural liquids from fruit, vegetables, and meats
    • Candles and metals such as nickel, jewelry, or utensils
    • Microbes, such as Staphylococcus aureus, viruses, and certain fungi may also bring out the symptoms of eczema.
    • House disinfectants like formaldehyde and vaccines
    • Antibacterial baby wipes like isothiazolinone.
    • Paraphenylenediamine, which you can use in dyes and tattoos
    • Emotional stress is a cause, but the explanation is unknown yet.
    • Hormonal changes have a role in increasing eczema symptoms in pregnancy and the menstrual cycle.
    • Neurodermatitis starts in patients who have psoriasis. The mechanism is still unknown, but stress may be a trigger.
    • Nummular eczema is a type of eczema that causes round, coin-shaped spots on your skin. These spots may become scaly. This type of eczema occurs due to an allergic reaction to insect bites, meats, or chemicals.
    • If fluid leaks out of your weakened veins into your skin, it will cause swelling, redness, itching, and pain in your skin. This condition occurs if there is a problem with the blood flow in your legs, as in varicose veins. This condition is called stasis dermatitis.
