What is Eczema?

Definition and overview

Eczema, also known as atopic dermatitis, is a chronic skin condition that affects millions of people worldwide. It is characterized by inflamed, itchy, and red patches of skin that can be persistent or intermittent. Eczema is often associated with a compromised skin barrier, making the skin more susceptible to irritation and allergens. While eczema is most commonly seen in infants and young children, it can also develop or persist into adulthood.

Types of eczema

There are several different types of eczema, each with its own unique characteristics and triggers. The most common type is atopic dermatitis, which typically begins in childhood and is often associated with a family history of allergies or asthma. Other types include contact dermatitis, which is caused by direct contact with irritants or allergens, and nummular eczema, which is characterized by coin-shaped patches of inflamed skin. Dyshidrotic eczema affects the hands and feet, while stasis dermatitis is often seen in individuals with poor circulation, particularly in the legs.

Common symptoms

The symptoms of eczema can vary depending on the individual and the type of eczema they have. However, some common symptoms include intense itching, dryness and flaking of the skin, redness and inflammation, thickened or leathery skin, and the formation of small, fluid-filled blisters. Scratching the affected areas can lead to further irritation, potentially causing the skin to crack, weep, or become infected. Eczema can also be accompanied by other symptoms such as sleep disturbances, anxiety, and depression.

Complications of Eczema

Skin infections

One of the major complications of eczema is the increased risk of skin infections. The constant scratching and compromised skin barrier can allow bacteria, viruses, and fungi to enter the skin, leading to infections. Common infections associated with eczema include impetigo, a bacterial infection characterized by yellowish, crusty sores; cellulitis, a bacterial infection that causes redness, warmth, and swelling in the affected area; and herpes simplex virus, which can cause a serious infection known as eczema herpeticum.

Psychological impact

Eczema can have a significant psychological impact on individuals, especially children. The chronic itching and discomfort can lead to frustration, anxiety, and even depression. Children with eczema may experience social isolation and low self-esteem due to the visible appearance of their skin. Additionally, the constant need to manage and treat eczema can be emotionally and mentally draining for individuals and their families.

Sleep disturbances

The incessant itching and discomfort caused by eczema can disrupt sleep patterns, leading to sleep disturbances and fatigue. Itchiness often worsens at night, making it challenging for individuals with eczema to get a good night’s sleep. Lack of quality sleep can further exacerbate stress, affect mood, and negatively impact overall quality of life. Restful sleep is essential for the body’s healing and repair processes, making it crucial for individuals with eczema to effectively manage their symptoms to improve sleep.

Eczema and Allergies

Connection between eczema and allergies

There is a clear connection between eczema and allergies, as both conditions are often seen in the same individuals or families. Eczema is considered part of the “atopic triad,” which also includes asthma and allergic rhinitis (hay fever). People with eczema have a higher likelihood of developing allergies, and vice versa. This suggests that there may be underlying immune system dysregulation that makes individuals more susceptible to both eczema and allergies.

Allergic contact dermatitis

Allergic contact dermatitis is a type of eczema that occurs when the skin comes into direct contact with a substance to which the person is allergic. Common allergens include nickel, fragrances, preservatives, latex, and certain medications. When the skin is exposed to these allergens, it reacts with inflammation, redness, and itching. Identifying and avoiding the specific allergens is key in managing this particular type of eczema.

Eczema herpeticum

Eczema herpeticum is a rare but serious complication that can occur when individuals with eczema are infected with the herpes simplex virus (HSV). The virus can invade the compromised skin barrier, leading to a widespread and painful rash that rapidly progresses. Eczema herpeticum requires prompt medical attention as it can cause severe illness and potential complications if left untreated. Antiviral medications are typically prescribed to treat this condition.

Eczema and Asthma

Link between eczema and asthma

Eczema and asthma often coexist in individuals, suggesting a link between the two conditions. People with eczema are more likely to develop asthma, and those with asthma may also experience symptoms of eczema. This connection is thought to be due to shared genetic and environmental factors that contribute to both conditions. However, the exact mechanisms behind this link are not fully understood and are the subject of ongoing research.

Atopic march

The concept of the “atopic march” refers to the sequential progression of allergic diseases, starting with eczema in infancy, followed by asthma and allergic rhinitis later in childhood. It is believed that eczema may serve as a gateway to the development of other allergic conditions. Early identification and management of eczema in children may help to reduce the risk of subsequent respiratory allergies, including asthma.

Risk factors

Several risk factors have been identified that increase the likelihood of an individual with eczema developing asthma. These include the severity and persistence of eczema symptoms, a family history of asthma or allergies, exposure to environmental allergens such as dust mites or pet dander, and exposure to tobacco smoke. It is important for individuals with eczema to be aware of these risk factors and take steps to minimize their impact on their respiratory health.

Eczema and Hay Fever

Relationship between eczema and hay fever

Eczema and hay fever, also known as allergic rhinitis, often coexist in individuals. Both conditions are considered part of the atopic triad, along with asthma. Like eczema, hay fever is an allergic reaction characterized by inflammation of the nasal passages in response to allergens such as pollen, dust mites, or animal dander. The underlying immune system dysregulation that predisposes individuals to eczema may also make them more susceptible to developing hay fever.

Allergic rhinitis

Allergic rhinitis is characterized by symptoms such as sneezing, nasal congestion, itching of the nose and eyes, and a runny nose. These symptoms can be particularly bothersome and affect an individual’s quality of life, especially during certain seasons when allergens are more prevalent. Managing both eczema and hay fever through proper treatment and allergen avoidance can help minimize the impact of these conditions on an individual’s overall well-being.

Shared risk factors

Eczema and hay fever share several risk factors, including a family history of allergies or the atopic triad, exposure to environmental allergens, and a compromised immune system. Additionally, certain lifestyle factors, such as exposure to cigarette smoke or air pollution, can increase the risk of both eczema and hay fever. By understanding and addressing these shared risk factors, individuals can take steps to reduce the likelihood of developing or exacerbating these conditions.

Eczema and Food Allergies

Association between eczema and food allergies

There is a well-established association between eczema and food allergies, particularly in infants and young children. Up to one-third of children with moderate to severe eczema may have food allergies. The link between the two conditions is complex, involving both genetic and environmental factors. While certain foods may trigger eczema flare-ups in some individuals, it is important to note that food allergies are not the primary cause of eczema.

Common trigger foods

Common trigger foods that may exacerbate eczema symptoms include cow’s milk, eggs, peanuts, soy, wheat, fish, and shellfish. However, it is essential to consult with a healthcare professional or allergist before eliminating any food groups from the diet, as a comprehensive evaluation is required to accurately identify specific food allergies. The elimination of trigger foods should be done under medical supervision to ensure proper nutrition and to avoid unnecessary dietary restrictions.

Atopic dermatitis and food allergies

Atopic dermatitis, the most common form of eczema, is often associated with the development of food allergies. The compromised skin barrier in individuals with eczema can allow food proteins to penetrate the skin and trigger an immune response, leading to food sensitization and the subsequent development of allergies. Understanding and managing this association is particularly important in infants and young children, as early intervention may help prevent the progression of eczema and the development of food allergies.

Eczema and Autoimmune Diseases

Possible connection between eczema and autoimmune diseases

While eczema is not classified as an autoimmune disease, there is evidence suggesting a possible connection between eczema and certain autoimmune disorders. Autoimmune diseases occur when the immune system mistakenly attacks healthy cells and tissues in the body. The underlying immune dysregulation seen in eczema may contribute to the development or increased risk of autoimmune conditions.

Autoimmune skin conditions

Some autoimmune skin conditions that have been associated with eczema include vitiligo, a disorder characterized by the loss of skin color in patches; alopecia areata, which causes hair loss; and celiac disease, an autoimmune disorder triggered by gluten consumption. The complex interplay between genetic factors, immune dysregulation, and environmental triggers is thought to contribute to the development of both eczema and autoimmune skin conditions.

Increased risk for certain autoimmune disorders

Research has suggested an increased risk of autoimmune diseases such as rheumatoid arthritis, lupus, and inflammatory bowel disease in individuals with a history of eczema. Although the precise mechanisms underlying these associations are still being studied, it is important to be vigilant for signs and symptoms of autoimmune diseases in individuals with eczema, as early detection and treatment can lead to better outcomes.

Eczema and Eye Disorders

Relation between eczema and eye disorders

Eczema can also affect the delicate skin around the eyes, leading to various eye disorders. The persistent itching and inflammation associated with eczema can irritate the eyes, causing discomfort and potentially affecting vision. Proper management and treatment of eczema can help minimize the risk of eye complications.


Blepharitis is a common eye disorder characterized by inflammation of the eyelids. In individuals with eczema, the eyelids may become red, swollen, and itchy. It can also cause the eyelids to become crusty and produce excessive eye discharge. Regular eyelid hygiene, including gentle cleansing and warm compresses, can help manage blepharitis symptoms and prevent flare-ups.


Conjunctivitis, commonly known as “pink eye,” can occur as a result of the inflammation and irritation caused by eczema. The conjunctiva, the thin layer of tissue that covers the white part of the eye, becomes inflamed, leading to redness, itching, and a gritty sensation in the eyes. Identification and management of eczema triggers, as well as proper eye care, are important in preventing or minimizing the occurrence of conjunctivitis in individuals with eczema.

Eczema and Skin Cancer

Potential association between eczema and skin cancer

Although the association between eczema and skin cancer is not fully understood, some studies have suggested a potential link. Chronic inflammation, a hallmark of eczema, may play a role in increasing the risk of developing certain types of skin cancer. However, it is important to note that the overall risk of developing skin cancer due to eczema remains relatively low, and the risk factors associated with skin cancer, such as excessive sun exposure, are still considered to be the primary causative factors.

Non-melanoma skin cancer

Non-melanoma skin cancer, including basal cell carcinoma and squamous cell carcinoma, has been reported to be more prevalent in individuals with eczema. The chronic inflammation and compromised skin barrier associated with eczema may contribute to the development of these types of skin cancer. Regular skin checks and sun protection measures, such as wearing sunscreen and protective clothing, are important for individuals with eczema to minimize the risk of skin cancer.

Increased risk due to chronic inflammation

Chronic inflammation caused by eczema may theoretically lead to genetic mutations and alterations in cellular processes that can increase the risk of developing skin cancer. However, more research is needed to better understand the complex relationship between eczema, chronic inflammation, and the development of skin cancer. It is important for individuals with eczema to be aware of their increased susceptibility and take necessary precautions to protect their skin.

Preventing Complications

Proper skin care

Proper skin care is crucial in preventing complications associated with eczema. This includes regularly moisturizing the skin to maintain its hydration, using mild and fragrance-free soaps and cleansers, avoiding excessive hot water during bathing or showering, and gently patting the skin dry after cleansing. Applying topical corticosteroids or other prescribed medications as directed by a healthcare professional can also help manage inflammation and prevent flare-ups.

Avoiding triggers

Identifying and avoiding triggers that exacerbate eczema symptoms is essential in preventing complications. Common triggers include certain foods, environmental allergens, harsh chemicals, and irritants like certain fabrics or skincare products. Keeping a diary to track potential triggers and consulting with a healthcare professional or allergist can help determine specific triggers and develop effective management strategies.

Regular medical check-ups

Regular medical check-ups with a dermatologist or healthcare professional experienced in treating eczema can help monitor the condition and prevent complications. These check-ups may include skin examinations, discussions about symptom management, updates on new treatment options, and potential referrals to specialists if needed. Early intervention and ongoing management can help individuals with eczema maintain optimal skin health and minimize the risk of complications.
