Overview of Eczema

Eczema is a chronic skin condition characterized by red, itchy, and inflamed skin. It is a common condition that affects people of all ages, from infants to adults. Eczema can have a significant impact on the quality of life, causing discomfort, skin rashes, and even emotional distress. Understanding the definition, types, prevalence, causes, triggers, hormonal changes, medications, lifestyle choices, risk factors, and management of eczema can help you better navigate this condition and find relief.

Definition of Eczema

Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition that leads to itchy, red, and dry patches of skin. It often occurs in cycles, with periods of flare-ups and remission. The exact cause of eczema is not fully understood, but genetic and environmental factors play a significant role.

Types of Eczema

There are several types of eczema, each with its own distinct characteristics. The most common types include atopic dermatitis, contact dermatitis, nummular eczema, and dyshidrotic eczema. Atopic dermatitis is the most prevalent type and typically begins in infancy or childhood. Contact dermatitis, on the other hand, occurs when your skin comes into contact with an irritant or allergen. Nummular eczema appears as circular patches of irritated skin, while dyshidrotic eczema affects the hands and feet, causing small blisters.

Prevalence of Eczema

Eczema is a widespread condition, affecting millions of people worldwide. It is estimated that around 15-20% of children and 1-3% of adults have eczema. The prevalence of eczema varies across different populations and geographic regions. While the exact reasons for these variances are not completely understood, factors such as genetics, environmental exposures, and lifestyle choices are believed to contribute to these differences.

Possible Causes of Eczema Development

Eczema is a complex condition influenced by various factors. Understanding these potential causes can provide insight into the development and management of eczema.

Genetic Factors

Genetics play a significant role in the development of eczema. If you have a family history of eczema, asthma, or hay fever, you are more likely to develop eczema yourself. Specific genes related to the skin’s protective barrier and immune system function are thought to contribute to the development of eczema.

Environmental Factors

Environmental factors can trigger or exacerbate eczema symptoms. Exposure to irritants such as chemicals, harsh soaps, detergents, and fragrances can irritate the skin and lead to eczema flare-ups. Additionally, pollution, humidity, and temperature changes can impact the skin’s moisture balance, making it more susceptible to eczema.

Immune System Dysfunction

Eczema is associated with an overactive immune system, which reacts to certain substances or allergens, triggering an inflammatory response in the skin. This immune system dysfunction can lead to chronic inflammation and the development of eczema.

Skin Barrier Dysfunction

The skin acts as a barrier, protecting the body from external factors. In individuals with eczema, there is a compromised skin barrier, allowing moisture to escape and allergens to penetrate the skin more easily. This leads to dryness, sensitivity, and inflammation, contributing to eczema development.


Allergies, particularly food allergies, can contribute to eczema development, especially in young children. Common food allergens such as milk, eggs, nuts, and soy may trigger or worsen eczema symptoms in susceptible individuals. Identifying and avoiding these allergens can help manage eczema.

Stress and Emotional Factors

Stress and emotional factors can also play a role in eczema development and flare-ups. Stress can weaken the immune system and increase inflammation, making eczema symptoms worse. Additionally, the emotional impact of living with eczema can further exacerbate the condition, leading to a vicious cycle of stress and flare-ups.

Triggers of Eczema Flare-ups

Identifying and avoiding triggers is crucial in managing eczema flare-ups. The following factors are commonly known to trigger or worsen eczema symptoms:


Allergens, such as pollen, pet dander, mold, and dust mites, can trigger eczema flare-ups in individuals who are allergic to these substances. Avoiding exposure to known allergens can help minimize eczema symptoms.


Chemicals, detergents, soaps, and fragrances can irritate the skin and trigger eczema symptoms. These irritants can disrupt the skin’s natural barrier function, leading to dryness, redness, and itching. Opting for fragrance-free and hypoallergenic products can help reduce irritation.

Hot or Cold Weather

Extreme temperatures, both hot and cold, can worsen eczema symptoms. Cold weather can cause dryness and exacerbate itchiness, while hot weather can lead to sweating and increased skin sensitivity. Protecting the skin from extreme temperatures and maintaining optimal humidity levels can help manage symptoms.


Sweating can trigger eczema flare-ups, as the salt and minerals found in sweat can irritate the skin. It is important to keep the skin cool and dry, especially during physical activities, to minimize the risk of sweat-induced flare-ups.

Dry Skin

Dry skin is a common trigger for eczema flare-ups. When the skin lacks moisture, it becomes more susceptible to irritation and inflammation. Regularly moisturizing the skin with hypoallergenic and fragrance-free lotions or creams can help prevent dryness and minimize eczema symptoms.


Skin infections, such as bacterial or viral infections, can worsen existing eczema or trigger new flare-ups. It is important to maintain good hygiene practices and promptly treat any skin infections to prevent complications.


Emotional stress and anxiety can significantly impact eczema symptoms. Stress can weaken the immune system and exacerbate inflammation, leading to more frequent and severe flare-ups. Adopting stress management techniques such as relaxation exercises, meditation, and therapy can help reduce stress levels and improve eczema management.

Certain Foods

Certain foods, such as dairy, eggs, soy, wheat, and nuts, can trigger eczema flare-ups in some individuals. It is important to identify and eliminate any food triggers from your diet to help manage eczema. Keeping a food diary and working with a healthcare professional can help pinpoint specific dietary triggers.

Hormonal Changes and Eczema

Hormonal changes can have a significant impact on eczema symptoms, particularly in women. Hormonal fluctuations during puberty, pregnancy, and menopause can influence eczema development and severity.


During puberty, hormonal changes can trigger or worsen eczema symptoms. The surge in hormones, such as estrogen and testosterone, can affect the skin’s oil production, leading to increased dryness and susceptibility to eczema flare-ups. Proper skincare and management techniques are essential during this period.


Pregnancy can bring about various hormonal changes, which can affect eczema. Some women experience improvements in their eczema symptoms during pregnancy, while others may notice flare-ups due to hormonal fluctuations and changes in the immune system. Proper skincare, gentle products, and regular moisturizing can help manage eczema during pregnancy.


Menopause brings about a decrease in estrogen levels, which can impact the skin’s moisture balance and contribute to eczema symptoms. Some women may experience a decrease in eczema symptoms during menopause, while others may notice flare-ups. Adhering to a consistent skincare routine and keeping the skin well-moisturized can help manage eczema during this transitional period.

Medications and Eczema

Certain medications can influence eczema symptoms, either positively or negatively. It is essential to be aware of the potential impact of medications on your condition.

Topical Steroids

Topical steroids are commonly prescribed to manage eczema symptoms. They provide relief by reducing inflammation and itching. However, long-term use of potent topical steroids can lead to adverse effects, such as thinning of the skin, discoloration, and stretch marks.


In some cases, eczema flare-ups may be triggered by bacterial infections on the skin. Antibiotics can be prescribed to treat these infections and improve eczema symptoms. However, it is important to follow a healthcare professional’s guidance and complete the full course of antibiotics.


There are various other medications used in the management of eczema, such as antihistamines to reduce itching, immunosuppressants to modulate the immune response, and moisturizers to keep the skin hydrated. It is essential to work closely with a healthcare professional to determine the most appropriate medications for your specific case.

Impact of Lifestyle Choices on Eczema

Certain lifestyle choices can influence the development and management of eczema. Making informed decisions can help alleviate symptoms and reduce the frequency of flare-ups.
