What kind of doctor treats Atopic Dermatitis?

A dermatologist, a skin doctor, treats atopic dermatitis. A primary care doctor can also treat milder eczema and start care. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.

What is atopic dermatitis?

Atopic dermatitis is a long-term skin disorder that involves scaly and itchy rashes. It is a type of eczema. It usually begins in early infancy and often disappears before adolescence. In some people it continues into adulthood. In others, it does not begin until adulthood. Hallmarks include dry, itchy skin and red rashes that come and go. The condition tends to wax and wane, meaning it flares and then calms. The itch can be so severe that it disturbs sleep.

Symptoms

Skin changes can include blisters that ooze and crust, dry skin, raw areas from scratching, and skin color changes. Thickened, leather-like skin can develop after long-term scratching. The rash location depends on age:

  • Infants: rashes commonly occur on the face, scalp, hands, and feet.
  • Children: rashes are usually found in the bend of the elbows and knees and on the front of the neck.
  • Teens and adults: rashes typically occur on the wrists, ankles, and eyelids, in addition to the bend of the elbows and knees.

Intense itching is common. Itching may start even before the rash appears. That is why it is often called the itch that rashes. Scratching can lead to oozing, crusting, and thickened skin, called lichenification.

Causes and who gets it

The cause is a combination of genetic and environmental factors. The strongest genetic link is the FLG gene. It is altered in 20 to 30 percent of people with atopic dermatitis. This gene helps the skin build a strong barrier that keeps water in and keeps out foreign substances. When the barrier is weak, allergens can get into the body through the skin, and water loss leads to dry skin. Not everyone with a risk gene develops the condition. Environmental factors also contribute. Allergic disorders tend to run in families. Having a parent with atopic dermatitis, asthma, or hay fever raises the chances. The condition is most common in infants. It may start as early as age 2 to 6 months. Many people outgrow it by early adulthood.

How doctors diagnose it

A dermatologist examines the skin and asks questions about symptoms, family history, and what makes symptoms worse. A skin exam along with health and symptom information is often enough for a diagnosis. Sometimes a skin biopsy, a small sample of skin checked under a microscope, is needed to confirm it or rule out other causes. Atopic dermatitis is often linked to other allergic disorders. Up to 60 percent of people with it develop asthma or hay fever later in life, and up to 30 percent have food allergies. This series is called the atopic march. Not everyone follows this pattern.

Treatment

This condition cannot be cured, but proper treatment can control it. Keeping the skin well moisturized helps prevent cracks that lead to worsening rash or infection. Most treatment plans include one or more of these:

  • Skin care: bathing, applying moisturizer, and being gentle with the skin.
  • Trigger management: finding and avoiding triggers, such as harsh skin care products, wool clothing, stress, fragrance, and harsh detergents.
  • Corticosteroid cream or ointment applied to the skin: many treatment plans include this, which can quickly relieve symptoms.
  • Topical calcineurin inhibitors, such as tacrolimus ointment or pimecrolimus cream, if steroids are not a good option.

For moderate to severe disease that is not well controlled, other medicines can help. Dupilumab, a biologic, is approved for people 6 months and older. It works by quieting the overactive part of the immune system. Tralokinumab is approved for people 12 and older. JAK inhibitor pills, such as upadacitinib, are approved for people 12 and older with moderate-to-severe disease. Phototherapy, in which the skin is carefully exposed to UV light, is another option.

When to see a doctor

Contact your doctor if the rash does not get better with home care, symptoms get worse, or treatment does not work. Get care right away if you have signs of a skin infection, such as fever, redness, or pain. People with atopic dermatitis are more prone to skin infections.

How a direct primary care or concierge doctor fits in

A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. This kind of doctor can treat milder eczema with skin medicines and help with daily skin care habits. They can also follow you over the long term and watch for related conditions like asthma and hay fever.

Common questions

Is atopic dermatitis contagious?

No. It is not an infection that passes between people. It is a skin condition tied to genes, the skin barrier, and the immune system.

Can atopic dermatitis be cured?

No. This condition cannot be cured, but proper treatment can control it. Treatment can reduce flare-ups, ease itch, and lower the risk of infection.

Will my child outgrow it?

Often yes. In children, the condition often starts to go away around age 5 to 6, but flare-ups will often occur. Some people continue to have it into adulthood.

What can make it worse?

Many things can trigger flares. Common ones include cold and dry air in the winter, contact with irritants and rough materials like wool, emotional stress, getting too hot or too cold, and perfumes or dyes in lotions or soaps.
