Eczema, also known as dermatitis, is a common inflammatory skin condition characterised by redness, itching, and dryness. It can affect individuals of all ages, from infants to adults.
Types of Eczema:
- Atopic Eczema:
A prevalent form that often begins in childhood, atopic eczema is associated with a personal or family history of allergic conditions such as asthma or allergic rhinitis. It typically presents as red, itchy rashes on the neck, face, and joints like the elbows and knees. - Contact Dermatitis:
This type arises when the skin reacts to substances it comes into contact with, leading to inflammation. There are two main subtypes:- Irritant Contact Dermatitis: Caused by exposure to irritants like detergents or solvents.
- Allergic Contact Dermatitis: Results from an allergic reaction to substances such as cosmetics or jewelry.
- Discoid Eczema:
Also known as nummular eczema, this form is characterised by round, coin-shaped patches of inflamed skin, commonly found on the arms and legs. It is more frequent in children and young adults. - Hand Eczema:
Specifically affecting the hands, this type can be triggered by factors like frequent hand washing, exposure to chemicals, or allergens. Symptoms include redness, dryness, and cracking of the skin on the hands. - Seborrhoeic Dermatitis:
This form affects areas rich in oil glands, such as the scalp, face, and chest. It presents as red, scaly, and itchy patches and is commonly known as dandruff when it affects the scalp.
Causes and Triggers:
Eczema arises from a combination of genetic predisposition and environmental factors. Common triggers include:
- Irritants: Soaps, detergents, and solvents.
- Allergens: Pollen, dust mites, and pet dander.
- Climate: Extremes of temperature and humidity.
- Stress: Emotional stress can exacerbate symptoms.
- Diet: Certain foods may trigger flare-ups in susceptible individuals.
Management and Treatment:
Effective management focuses on alleviating symptoms and preventing flare-ups:
- Moisturising: Regular application of emollients to keep the skin hydrated.
- Topical Treatments: Use of steroid creams or ointments to reduce inflammation.
- Avoidance of Triggers: Identifying and minimising exposure to known irritants and allergens.
- Medical Consultation: Seeking advice from healthcare professionals for personalised treatment plans.
