Atopic (genetic predisposition) dermatitis affects 1 in 5 children and 1 in 12 adults in the UK. It is characterised by dry, itchy patches commonly localised to the neck, hands, feet, elbows, and the back of the legs. A dysregulated immune system develops and progresses eczema: > A well-balanced immune system relies on Th1 cells (respond to bacteria, viruses and abnormal cells), and Th2 cells (target extracellular pathogens such as allergens), working in harmony. > During pregnancy, the maternal immune system adapts to see the foetus as ‘self’ rather than ‘foreign’. It suppresses Th1 to accept the baby, leading to Th2 dominance which predisposes the baby to allergies when born. > After birth, the infant’s gut is colonised by beneficial bacteria from mum (via a vaginal delivery and/or breastfeeding) which helps to re-balance Th1 and Th2 cells, ensuring a tolerant immune system. > C-section births, formula feeding, and early antibiotic use, impair proper development of the infant’s gut microbiome. Together with low vitamin D status (common in UK), Th2 dominance can persist. > This immune dysregulation increases antibody (IgE) production which causes excessive immune reactions to otherwise harmless substances (e.g. pollen, dust, certain foods). > This increases inflammation, which can irritate cells in the epidermis, contributing to an eczema flare-up. As the immune system remains activated, the body can also release higher amounts of histamine to increase blood vessel permeability and allow immune cells to get to tissues. Individuals with allergies tend to have a higher baseline histamine level, prolonging inflammatory response and creating a vicious cycle. DNA’s advice on how to manage eczema: 1/ probiotic foods, such as fermented tofu, sauerkraut, coconut kefir, and kimchi. 2/ check for birch pollen-linked reactions (apples, carrots, celery and hazelnuts) 3/ kale, spinach, blueberries, red onions and red apples (if no reaction) 4/ bell pepper, broccoli, kale, citrus fruits, kiwis, 5/ omega-3 foods – salmon, mackerel, sardines, herring, flax & chai seeds. 6/ cook with turmeric (add to soups, stews, omelets), or add to hot water, ginger and lemon. 7/ nettle leaf herbal tea has anti-inflammatory and antihistamine properties. Supplements Depending on your medical history & symptoms, your naturopathic nutritionist may advise: 1/ Vitamin A 2/ Vitamin D 3/ Vitamin E 4/ Zinc
