Solutions for Eczema
Eczema: it’s a word that might make you scratch just thinking about it. If you’re one of the people grappling with this persistent skin condition, you should know you’re not alone. Eczema affects up to 10% of the UK population, turning everyday activities into uncomfortable challenges and peaceful nights into itchy ordeals.
But what exactly is it, and why does it seem to have a mind of its own? Whether you’re dealing with occasional flare-ups or constant irritation, understanding this complex condition is the first step towards finding relief. Dr Dalia, a dermatologist with many years of experience, can help you manage your condition and reclaim comfort.
What is Eczema?
Eczema, also known as atopic dermatitis, is more than just a skin condition—it’s a complex interplay of genetic, environmental, and immunological factors. But what does this mean for you and your skin?
At its core, it is an inflammatory skin condition characterised by itchy, red, and sometimes weepy patches of skin. It’s like your skin’s alarm system is constantly going off, even when there’s no real threat. This oversensitivity leads to the hallmark symptoms that many of you are all too familiar with.
But did you know that it isn’t just one condition? There are actually several types, each with its own quirks:
- Atopic Dermatitis: The most common form, often starting in childhood. It’s the classic eczema that many think of, with dry, itchy skin that can appear anywhere on the body.
- Contact Dermatitis: This type occurs when your skin reacts to something it touches. It could be an irritant (like soap or chemicals) or an allergen (like nickel in jewellery).
- Dyshidrotic Eczema: This peculiar type causes small, intensely itchy blisters on the palms and soles. It’s often triggered by stress or excessive hand washing.
- Nummular Eczema: Characterised by coin-shaped patches, this type can be particularly stubborn and is often mistaken for fungal infections.
- Seborrheic Dermatitis: This type affects areas rich in oil glands, like the scalp, face, and chest. It’s what we call ‘cradle cap’ in babies.
Eczema Symptoms
Each type of eczema can present differently, but they all share common symptoms. You might experience:
- Intense itching, often worse at night
- Dry, sensitive skin
- Inflamed, discoloured patches
- Rough, leathery, or scaly areas
- Oozing or crusting
- Areas of swelling
One of the most frustrating aspects of this condition is its chronic nature. It tends to flare up and then subside, often without any apparent reason. This unpredictability can be emotionally taxing, affecting not just your skin but your overall quality of life.
Causes of Eczema
The exact cause of eczema remains a bit of a medical mystery. However, research has uncovered several factors that contribute to its development and persistence. Here are some of these factors:
Genetic Factors
If you have this condition, you can partly blame your genes. Studies have shown that if one or both parents have it, their children are more likely to develop it too. Specifically, mutations in the gene responsible for creating filaggrin—a protein that helps maintain a healthy skin barrier—have been linked to some types of eczema.
But here’s an interesting twist: having the gene doesn’t guarantee you’ll develop it, and not having it doesn’t mean you’re immune. This is where other factors come into play.
Environmental Triggers
Your environment plays a role in eczema flare-ups. Common triggers include:
- Harsh soaps and detergents
- Certain fabrics (especially wool and synthetic materials)
- Dust mites
- Pet dander
- Pollen
- Extreme temperatures
- Low humidity
These environmental factors can irritate your skin or trigger an allergic response, leading to those familiar eczema symptoms.
Immune System Dysfunction
Eczema is considered an autoimmune condition, meaning your immune system is overreacting to minor irritants or allergens. This overreaction leads to inflammation in the skin, causing the redness, swelling, and itching characteristic of eczema.
People with eczema often have higher levels of a type of antibody called IgE. This antibody is typically involved in fighting parasitic infections, but in eczema, it seems to be misdirected, causing inflammation in response to harmless substances.
Skin Barrier Defects
Your skin acts as a barrier, protecting your body from irritants, allergens, and moisture loss. In people with eczema, this barrier doesn’t work as well as it should. This can be due to genetic factors (remember that filaggrin protein we mentioned?) or can develop over time due to environmental damage.
A compromised skin barrier allows irritants and allergens to penetrate more easily, triggering inflammation. It also allows more moisture to escape, leading to dry, easily irritated skin.
Lesser-Known Causes
While the above factors are well-established, researchers are continually uncovering new potential causes of eczema:
- Microbiome imbalance: Recent studies suggest that an imbalance in the skin’s microbiome (the collection of microorganisms living on your skin) may contribute to eczema.
- Vitamin D deficiency: Some research indicates a link between low vitamin D levels and increased eczema severity.
- Stress: While not a direct cause, stress can significantly exacerbate eczema symptoms, possibly by affecting immune function and skin barrier repair.
- Air pollution: Emerging evidence suggests that exposure to air pollutants may increase the risk of developing eczema or worsening existing symptoms.
- Gut health: There’s growing interest in the gut-skin axis, with some studies suggesting that gut health and the gut microbiome may play a role in eczema development.
Triggers and Exacerbating Factors for Eczema
It’s also important to understand the factors that can trigger flare-ups or make existing symptoms worse. You can considerably reduce the frequency and severity of your eczema outbreaks by identifying these triggers:
Allergens and Irritants
Your skin comes into contact with countless substances every day, and for those with eczema, many of these can spell trouble. Common irritants include:
- Fragrances in skincare products and laundry detergents
- Certain metals, especially nickel
- Formaldehyde, which can be found in household disinfectants
- Isothiazolinones, preservatives used in many personal care products
- Cocamidopropyl betaine, a surfactant in many shampoos and body washes
- Some people with eczema may also react to certain foods. While food allergies don’t cause the condition, they can trigger flare-ups in some individuals. Common food triggers include dairy, eggs, nuts, and wheat.
Stress and Emotional Factors
Have you ever noticed your eczema worsening during periods of high stress? You’re not alone. Stress can have a significant impact on the symptoms, creating a frustrating cycle: stress exacerbates it, which in turn causes more stress.
This stress-eczema connection is thought to be due to the effect of stress hormones on the immune system and inflammation. Additionally, stress can lead to behaviours that worsen the condition, such as reduced sleep or increased scratching.
Climate and Weather Conditions
Your skin’s nemesis might be lurking in the forecast. Many people with eczema find that their symptoms are influenced by weather conditions:
- Cold, dry weather can lead to moisture loss from the skin, exacerbating dryness and irritation.
- Hot weather can cause sweating, which may irritate the skin and lead to itching.
- Sudden temperature changes can trigger flare-ups.
- Low humidity environments, whether due to weather or indoor heating, can dry out the skin.
Some people find that their eczema improves in sunny weather. This could be due to the beneficial effects of UV light on the immune system, or the increase in vitamin D production.
Hormonal Changes
For many women, eczema symptoms can fluctuate with hormonal changes. You might notice flare-ups:
- Before or during menstrual periods
- During pregnancy
- After giving birth
- During menopause
These hormonal fluctuations can affect skin hydration, oil production, and even the way your immune system responds to irritants.
Diet and Nutrition
While the link between diet and eczema isn’t fully understood, what you eat can potentially influence your symptoms. Some studies suggest that a diet high in fruits, vegetables, and omega-3 fatty acids may help reduce inflammation and improve eczema symptoms.
On the flip side, some foods might exacerbate eczema in certain people:
- Dairy products
- Eggs
- Soy products
- Gluten
- Tomatoes
- Some types of nuts
Diagnosis for Eczema
Diagnosing eczema might seem straightforward – after all, it’s visible on your skin, right? However, because eczema can mimic other skin conditions, a proper diagnosis from a dermatologist like Dr Dalia is essential for effective treatment.
When you visit Dr Dalia for eczema concerns, here’s what you can expect:
- Visual Examination: Dr Dalia will carefully examine your skin, looking at the pattern and appearance of the affected areas.
- Medical History: Dr Dalia will ask about your symptoms, when they started, and any factors that seem to trigger or worsen them.
- Family History: Since eczema often runs in families, Dr Dalia will inquire about any relatives with eczema, allergies, or asthma.
- Patch Testing: In some cases, especially if contact dermatitis is suspected, she might recommend patch testing to identify specific allergens.
But when should you book that appointment? Here are some signs that it’s time to seek professional help for eczema:
- Your eczema is interfering with your sleep or daily activities
- Over-the-counter treatments aren’t providing relief
- You’re experiencing frequent flare-ups
- There are signs of skin infection (increased redness, warmth, pus, or fever)
- Your eczema is affecting your mental health or self-esteem
Treatment Options for Eczema
Here are some treatment options for eczema:
Topical Treatments
- Corticosteroids: These anti-inflammatory creams and ointments come in various strengths. They’re effective for reducing inflammation and itching, but long-term use requires careful monitoring due to potential side effects.
- Calcineurin Inhibitors: These medications can be particularly useful for sensitive areas like the face and eyelids. They work by suppressing the immune response in the skin.
- Moisturisers and Emollients: Never underestimate the power of a good moisturiser! Keeping your skin well-hydrated is essential for managing eczema. Look for products with ingredients like ceramides, which help repair the skin barrier.
Systemic Treatments
For more severe or widespread eczema, systemic treatments might be necessary.
- Oral Medications: These might include oral corticosteroids for short-term use in severe flares, or immunosuppressants for long-term control.
- Biologics: These newer drugs work by targeting specific parts of the immune system involved in eczema. They can be recommended for people with severe eczema that hasn’t responded to other treatments.
Natural and Alternative Remedies
While scientific evidence varies, some people find relief with:
- Coconut oil, known for its moisturising and antimicrobial properties
- Colloidal oatmeal baths to soothe itchy skin
- Acupuncture, which may help reduce itching in some people
- Relaxation techniques to manage stress-related flares
Skincare Routines for Eczema-Prone Skin
Here are some recommendations:
In the Shower
- Opt for lukewarm (not hot) showers or baths, limiting them to 10-15 minutes
- Use gentle, fragrance-free cleansers
- Apply moisturiser immediately after bathing to lock in hydration
- Consider the “soak and seal” method: soak in a lukewarm bath, pat dry, and immediately apply medication (if prescribed) followed by moisturiser
Clothing Choices and Fabrics
- Choose soft, breathable fabrics like cotton
- Avoid rough materials like wool and synthetic fibres
- Opt for loose-fitting clothes to reduce friction on your skin
- Remove labels from clothing, as these can irritate the skin
Home Environment Changes
- Use a humidifier to add moisture to dry air
- Keep your home cool to reduce sweating
- Vacuum and dust regularly to reduce allergens
- Use hypoallergenic bedding and wash it weekly in hot water
Diet and Nutrition Tips
- Stay hydrated by drinking plenty of water
- Consider an anti-inflammatory diet rich in omega-3 fatty acids, found in fish, flaxseeds, and walnuts
- If you suspect food triggers, keep a food diary and consider an elimination diet under medical supervision
- Some people find probiotics helpful, although more research is needed in this area
FAQs about Causes and Treatment for Eczema
Can eczema be cured completely?
- While there’s currently no permanent cure for eczema, many people experience long periods of remission where symptoms are minimal or absent. With proper management and treatment, it’s possible to control symptoms effectively and significantly improve quality of life. Research is ongoing, and new treatments are continually being developed that may offer better long-term solutions in the future.
Is eczema contagious?
- No, eczema is not contagious. You cannot catch it from someone else or spread it to others through physical contact. However, if it becomes infected (a condition called eczema impetiginisation), the infection itself may be contagious. This is why it’s important to keep the affected skin clean and seek treatment if you suspect an infection.
Can certain vitamins or supplements help with this condition?
- Some studies suggest that certain vitamins and supplements may help manage the symptoms. Vitamin D, vitamin E, and zinc have shown potential benefits in some research. Evening primrose oil and fish oil supplements are also sometimes recommended.
How does it affect people of different skin colours?
- Eczema can affect people of all skin tones, but it may look different and be diagnosed differently in people with darker skin. In lighter skin, it typically appears red or pink. In darker skin, it might look darker brown, purple, or grey, and can be more difficult to detect visually. This can sometimes lead to delayed diagnosis or misdiagnosis. Additionally, people with darker skin may be more prone to skin discolouration (hyperpigmentation or hypopigmentation) after flares.
Is there a link between eczema and other health conditions?
- Yes, it is associated with several other health conditions. People with this condition are more likely to develop asthma and hay fever, a triad known as the “atopic march”. There’s also an increased risk of certain skin infections due to the compromised skin barrier. Some studies have found links between this condition and mental health conditions like anxiety and depression. More recently, research has suggested potential associations with cardiovascular disease and certain autoimmune disorders, although more studies are needed to fully understand these relationships.
