Atopic Dermatitis-Dr-Colin-Hong

Are you suffering from the red, scaly patches of a skin irritation known as atopic dermatitis? You are not alone. Atopic dermatitis is a common skin condition also known as eczema that affects millions of people around the world. It can affect individuals of all ages and ranges in severity from mild to severe. 

Here, we will explore what causes atopic dermatitis, how it is diagnosed and treated, and how to find relief when living with this chronic condition. We hope that by discussing the symptoms, diagnosis, and treatment options available, those who suffer can take charge and manage their condition more effectively.

History and Definition

Atopic dermatitis, also known as eczema, is a chronic inflammatory skin condition characterized by red, itchy, and scaly skin. The condition is common in children and can persist into adulthood, affecting up to 10% of the population.

The term “atopic” was first introduced by Dr. Coca and Dr. Cooke in 1923 to describe a hypersensitivity reaction to an unknown substance. However, it was not until 1933 that Fred Wise and Marion Sulzberger introduced the term “atopic dermatitis” to describe the condition characterized by a triad of symptoms: eczema, hay fever, and asthma.

Atopic dermatitis was originally thought to be caused by an allergy to an unknown substance. However, the current understanding of the condition involves a complex interplay of genetic and environmental factors. People with atopic dermatitis have a weakened skin barrier, which allows for increased water loss and susceptibility to irritants and allergens. This, in turn, triggers an inflammatory response in the skin, leading to the characteristic symptoms of atopic dermatitis.


Common symptoms of atopic dermatitis include:

  • Itchy skin: Itching is the most common symptom of atopic dermatitis, and it can be severe, leading to significant discomfort and disruption of daily activities.


  • Red or inflamed skin: The skin affected by atopic dermatitis may appear red, inflamed, and swollen. In some cases, the skin may also feel warm to the touch.


  • Dry or scaly skin: Atopic dermatitis can cause the affected skin to become dry, scaly, and rough. In some cases, the skin may also crack, peel, or become crusty.


  • Bumps or blisters: Some people with atopic dermatitis may develop small, fluid-filled bumps or blisters on their skin. These bumps may ooze or crust over if scratched.


  • Thickened or leathery skin: In chronic cases of atopic dermatitis, the skin may become thickened and leathery in texture. This is known as lichenification and can occur on areas of the skin that have been repeatedly scratched.


  • Sleep disturbances: Itching and discomfort caused by atopic dermatitis can interfere with sleep, leading to fatigue and reduced quality of life.

It’s important to note that the symptoms of atopic dermatitis can vary in severity and may come and go over time. If you are experiencing any of the above symptoms, it’s important to consult with a healthcare provider for an accurate diagnosis and appropriate treatment plan.


The exact cause of atopic dermatitis is not fully understood, but it is thought to be the result of a combination of genetic, environmental, and immunological factors.

  • Genetics: Atopic dermatitis often runs in families, suggesting that there may be a genetic component to the condition. Several genes have been identified that may increase the risk of developing atopic dermatitis, and these genes may also play a role in the immune system’s response to allergens and other triggers.


  • Environmental factors: Environmental factors, such as exposure to allergens, irritants, and microbes, can trigger or exacerbate atopic dermatitis symptoms. Common triggers include dust mites, animal dander, pollen, certain foods, and harsh soaps or detergents. Changes in temperature, humidity, and stress levels may also trigger flare-ups.


  • Immunological factors: The immune system is thought to play a role in the development of atopic dermatitis, as the condition is often associated with increased levels of inflammatory cells and cytokines. In individuals with atopic dermatitis, the skin’s barrier function is compromised, allowing allergens and irritants to penetrate the skin and trigger an immune response.


Diagnosing atopic dermatitis typically involves a physical examination and a review of the individual’s medical history and symptoms. Here are some of the steps a healthcare provider may take to diagnose atopic dermatitis:

  • Medical history: The healthcare provider will ask about the individual’s symptoms, including when they first appeared, how long they have been present, and whether there are any triggers or factors that make the symptoms worse.


  • Physical examination: The healthcare provider will examine the skin for the characteristic signs of atopic dermatitis, including redness, itching, dryness, and scaling. They may also look for signs of infection or other conditions that can cause similar symptoms.


  • Allergy testing: If the healthcare provider suspects that the individual’s symptoms may be caused by an allergy, they may recommend allergy testing. This can involve skin prick testing or blood tests to identify allergens that may be triggering the symptoms.

  • Biopsy: In rare cases, a skin biopsy may be performed to help confirm the diagnosis of atopic dermatitis and rule out other conditions that can cause similar symptoms.

Usually, there is no single test to diagnose atopic dermatitis, and the diagnosis is typically based on a combination of the individual’s medical history, physical examination, and other factors.


The treatment of atopic dermatitis typically involves a combination of strategies to relieve symptoms, repair and protect the skin barrier, and prevent flare-ups. Here are some of the common treatment options:

  • Topical creams and ointments: These can help relieve itching and inflammation, repair the skin barrier, and prevent infection. Examples of topical medications include corticosteroids, calcineurin inhibitors, and moisturizers.


  • Oral medications: In some cases, oral medications may be used to control symptoms or prevent complications. Examples include antihistamines to relieve itching, antibiotics to treat bacterial infections, and immunosuppressive medications to reduce inflammation.


  • Wet wrap therapy: This involves applying a damp layer of bandages or clothing over the affected skin after applying medication. This can help soothe the skin, reduce itching, and improve medication absorption.


  • Light therapy: Exposure to certain types of light, such as narrowband ultraviolet B (UVB) or UVA, can help reduce inflammation and improve symptoms.


  • Lifestyle changes: Making changes to the environment, such as using a humidifier, avoiding triggers such as certain fabrics or irritants, and managing stress, can help prevent flare-ups.

Surgical treatments are generally not used to treat atopic dermatitis, as the condition does not typically require surgery. In severe cases, however, a procedure called skin grafting may be used to repair skin that has been damaged or scarred by atopic dermatitis.

With proper treatment, symptoms of atopic dermatitis can be managed and controlled, and most people with the condition can lead normal healthy lives. It’s important to follow the healthcare provider’s recommended treatment plan and attend follow-up appointments to monitor progress and make any necessary adjustments.

Risk Factors

Several risk factors have been identified for atopic dermatitis, including:

  • Genetics: Atopic dermatitis has a strong genetic component, with a family history of the condition being a major risk factor. Children with one parent with atopic dermatitis have a 50% chance of developing the condition, while those with both parents affected have an even higher risk.


  • Age: Atopic dermatitis is most common in infants and young children, with 60% of cases occurring in the first year of life. However, the condition can also develop in adults.


  • Environmental factors: Exposure to certain environmental factors can increase the risk of developing atopic dermatitis, including dry air, cold weather, heat, humidity, pollution, dust, and certain types of fabrics.


  • Allergies: People with other allergic conditions, such as hay fever or food allergies, have an increased risk of developing atopic dermatitis.


  • Ethnicity: Atopic dermatitis is more common in people of certain ethnic backgrounds, including African Americans, Asian Americans, and Hispanic/Latino Americans.


  • Stress: Emotional stress can trigger or worsen atopic dermatitis symptoms in some individuals.

Having one or more of these risk factors does not necessarily mean that an individual will develop atopic dermatitis. However, individuals with a higher number of risk factors may be more likely to develop the condition or experience more severe symptoms. If you are at increased risk for atopic dermatitis, it’s important to take steps to prevent or manage symptoms and talk to a healthcare provider if you notice any signs of the condition.


Atopic dermatitis can lead to several complications, including:

  • Skin infections: Scratching the itchy skin associated with atopic dermatitis can break the skin barrier, making it more vulnerable to infection. Bacterial, viral, and fungal infections can all occur in the affected skin.


  • Chronic itch and sleep disturbances: The intense itching associated with atopic dermatitis can lead to chronic itch and sleep disturbances, which can in turn affect mood, concentration, and quality of life.


  • Impaired skin barrier: Atopic dermatitis can damage the skin barrier, leading to dryness, cracking, and increased vulnerability to environmental irritants and allergens.


  • Hyperpigmentation and scarring: Repeated scratching and rubbing of the affected skin can cause hyperpigmentation and scarring, especially in darker-skinned individuals.


  • Psychological distress: Living with atopic dermatitis can be challenging, and the condition can cause anxiety, depression, and other psychological distress in some individuals.


  • Eye complications: In rare cases, atopic dermatitis can affect the eye area, causing eye complications such as inflammation of the eyelids (blepharitis), eye infections, or keratoconus, a condition that causes thinning and bulging of the cornea.

When to See a Doctor

It is recommended to see a doctor if you suspect that you have atopic dermatitis, or if you have symptoms that suggest an infection or other complication. Here are some specific situations when it is important to seek medical attention:

  • Severe itching and discomfort: If you are experiencing severe itching, pain, or discomfort that is not relieved by over-the-counter treatments or affects your daily life, it may be time to see a doctor.


  • Skin infection: If you notice signs of infection in the affected skin, such as pus, redness, or swelling, you should see a doctor immediately.


  • Bleeding or oozing skin: If your skin is bleeding or oozing, it may be a sign that the condition is getting worse and requires medical attention.


  • Sleep disturbances: If your atopic dermatitis is causing sleep disturbances, it may be time to see a doctor to discuss treatment options.


  • Psychological distress: If you are experiencing anxiety, depression, or other psychological distress related to your condition, it is important to seek help from a healthcare professional.


  • Worsening symptoms: If your atopic dermatitis is getting worse or not responding to treatment, you should see a doctor to discuss alternative treatment options.


In general, it is a good idea to see a doctor if you have any concerns about your skin or if you are experiencing symptoms that are affecting your daily life. Your doctor can help you manage your symptoms and prevent complications, and may refer you to a dermatologist or a plastic surgeon if needed.

The first step in treating atopic dermatitis is to consult with a healthcare provider, such as a primary care physician, plastic surgeon, or dermatologist. During the consultation, the healthcare provider will ask about your symptoms and medical history and may perform a physical examination of the affected skin.


Based on your symptoms and physical examination, your healthcare provider will make a diagnosis of atopic dermatitis. They may also order additional tests, such as allergy tests or skin biopsies, to rule out other conditions or identify triggers that may be exacerbating your symptoms.

Treatment Plan

Once a diagnosis of atopic dermatitis is confirmed, your healthcare provider will work with you to develop a treatment plan tailored to your specific symptoms and needs. This may include a combination of topical treatments, such as moisturizers, steroid creams, and immune-modulating medications, as well as lifestyle changes, such as avoiding triggers and practicing good skin hygiene.

Treatment Process

The treatment process will depend on the specific medications and lifestyle changes recommended by your healthcare provider. Topical treatments may need to be applied several times per day and may be tapered off over time as symptoms improve. Lifestyle changes, such as avoiding triggers and practicing good skin hygiene, may also need to be maintained long-term to prevent flare-ups.

Follow-Up Appointments

Your healthcare provider may schedule follow-up appointments to monitor your progress and adjust your treatment plan as needed. They may also perform additional tests or refer you to a specialist if your symptoms do not improve or if you experience complications.

After Treatment

After treatment, it is important to continue practicing good skin hygiene and avoiding triggers to prevent future flare-ups. Your healthcare provider may recommend ongoing maintenance treatment, such as using a daily moisturizer or steroid cream, to keep your symptoms under control. It is also important to attend regular follow-up appointments to monitor your progress and prevent complications.

Overall, the treatment of atopic dermatitis is a collaborative process between the patient and healthcare provider and may involve a combination of topical treatments, lifestyle changes, and ongoing monitoring to manage symptoms and prevent complications.


In conclusion, atopic dermatitis is a chronic skin condition that affects millions of people worldwide. It is characterized by red, itchy, and inflamed patches of skin that can be very uncomfortable and interfere with daily activities. Although there is no cure for atopic dermatitis, there are many treatment options available to help manage symptoms and prevent complications. These treatments may include topical medications, lifestyle changes, and regular monitoring by a healthcare provider. 

Individuals with atopic dermatitis need to work closely with their healthcare provider to develop a treatment plan tailored to their specific needs and symptoms. With proper management and care, it is possible to live a healthy and comfortable life with atopic dermatitis.
