Understanding Eczema: Causes, Symptoms, and Treatments


Eczema, a term that resonates with many, is often surrounded by misconceptions and myths. As a skin expert, I’ve seen firsthand the physical and emotional toll it takes on individuals. Today, we’ll embark on a comprehensive journey into eczema, aiming to demystify this prevalent skin condition.

What is Eczema?

Eczema, also known as atopic dermatitis, is a chronic skin condition that presents as inflamed, itchy skin. There are several types, including contact dermatitis, dyshidrotic eczema, and nummular eczema, each with distinct characteristics. Historically, ancient Egyptian and Greek texts have mentioned eczema-like symptoms, highlighting its longstanding presence. Recent studies suggest that up to 20% of children and 3% of adults globally are affected by some form of eczema.

Understanding Eczema: Causes, Symptoms, and Treatments

Causes of Eczema

Eczema’s exact cause remains elusive, but several factors play a role:

  • Genetic Factors: Mutations in certain genes can make individuals more susceptible. If both parents have eczema, there’s a higher likelihood their child will too.
  • Environmental Triggers: Beyond common allergens like pollen and pet dander, even urban pollution and prolonged water exposure can be culprits. Moreover, harsh chemicals in personal care products can disrupt the skin’s barrier.
  • Climate: Regions with low humidity or extreme cold can strip the skin of its natural moisture, leading to flare-ups.
  • Foods: It’s not just about allergies. Even without a direct allergy, certain foods can cause inflammation in some individuals, exacerbating eczema.
  • Stress and Hormonal Changes: Chronic stress releases inflammation-causing chemicals. Additionally, women might notice flare-ups around their menstrual cycle or during pregnancy due to hormonal fluctuations.

Symptoms of Eczema

While symptoms vary, there are commonalities:

  • Common Symptoms: The hallmark is itching, which can become so severe it disrupts sleep. This is accompanied by red or brownish patches, especially on the hands, feet, and neck.
  • Less Common Symptoms: Blisters that ooze and then crust over can appear, especially after scratching. Over time, repeated scratching or rubbing can cause the skin to thicken.
  • Severity Levels: Eczema’s unpredictability means some might experience infrequent mild episodes, while others grapple with constant severe symptoms.

Diagnosis and Testing

A dermatologist will typically start with a visual examination and a review of medical history. They might ask:

  • When did the symptoms start?
  • Are there known allergens or irritants?
  • What treatments have been tried?

In ambiguous cases, a biopsy might be taken. Patch testing can also identify potential allergens.

Treatment Options

Eczema’s chronic nature means treatment focuses on managing symptoms:

  • Topical Treatments: Beyond steroids, there are now advanced topical immunomodulators like tacrolimus and pimecrolimus that reduce inflammation without the side effects of steroids.
  • Oral Medications: For severe cases, oral steroids might be prescribed short-term. Newer drugs, like biologics, target specific parts of the immune system.
  • Light Therapy: Controlled exposure to UV light, often combined with medications, can reduce itching and inflammation.
  • Natural and Alternative Treatments: Evening primrose oil, taken orally, has shown some promise. Acupuncture and hypnosis are also being explored for their potential benefits.
  • Lifestyle Changes: Simple steps, like keeping nails short to prevent scratching and wearing soft, breathable fabrics, can make a significant difference.

Living with Eczema

Beyond the physical symptoms, eczema can impact mental well-being, leading to anxiety or depression. It’s crucial to:

  • Establish a daily skincare routine.
  • Use hypoallergenic products.
  • Seek emotional and psychological support, be it through therapy or support groups.


Eczema is more than skin-deep. It’s a complex interplay of genetic, environmental, and psychological factors. But with advancing research and a holistic approach, it’s possible to lead a fulfilling life despite eczema. Always consult with a dermatologist for personalized advice.
