Dermatitis is a general term that describes a common skin irritation. It has many causes and forms and usually involves itchy, dry skin or a rash. Or it might cause the skin to blister, ooze, crust, or flake off. Three common types of this condition are atopic dermatitis (eczema), seborrheic dermatitis, and contact dermatitis.
Is there a difference between eczema and
dermatitis?
Although the
terms “dermatitis” and “eczema” may overlap in how they’re used, specific types
of skin conditions are better known by just one of the names. For example, many
doctors use the terms “atopic dermatitis” and “eczema” interchangeably but
wouldn’t use the term “contact dermatitis” in place of “eczema.”
Dermatitis means
inflammation of the skin. Eczema is inflamed skin that has other symptoms like
itching, a flaky or scaly rash, and dry skin.
Dermatitis isn't
contagious, but it can make you feel uncomfortable and self-conscious.

·
You suspect that your skin is infected
·
You've tried self-care steps but your signs and
symptoms persist
Eczema stages
Eczema can be
broken down into three stages:
1.
Chronic:
This is the most common stage of eczema, and it often develops in children
before they’re 12 months old. Chronic eczema generally lasts over a lifetime
with occasional flare-ups, although childhood eczema may improve with age.
2. Acute:
Short-term eczema may be the result of skin sensitivities after coming into
contact with an irritating substance. Acute cases last just a few weeks as your
skin heals.
3.
Subacute:
This is part of the healing phase of eczema, which can still flare back up into
a full rash if left untreated.
Causes
A common cause
of dermatitis is contact with something that irritates your skin or triggers an
allergic reaction for example, poison ivy, perfume, lotion, and jewelry
containing nickel. Other causes of dermatitis include dry skin, a viral
infection, bacteria, stress, genetic makeup, and a problem with the immune
system.
Eczema is also caused
by underlying inflammation. The development of this inflammatory skin condition
involves substances that create negative immune reactions. These include
various allergens as well as hereditary and environmental factors.
While eczema
isn’t a contagious disease, it does tend to run in families. You may be
especially at risk if a parent or other relative has a history of allergies and
related eczema symptoms.
Digestive issues
and food sensitivities can also play a role, although their links to eczema
aren’t as well established.
Risk factors
Common risk
factors for dermatitis include:
·
Age:
Dermatitis can occur at any age, but atopic dermatitis (eczema) is more common
in children than adults, and it usually begins in infancy.
·
Allergies
and asthma: People who have a personal or family history of eczema,
allergies, hay fever, or asthma are more likely to develop atopic dermatitis.
·
Occupation:
Jobs that put you in contact with certain metals, solvents, or cleaning
supplies increase your risk of contact dermatitis. Being a health care worker
is linked to hand eczema.
·
Health
conditions: Health conditions that put you at increased risk of seborrheic
dermatitis include congestive heart failure, Parkinson's disease, and HIV/AIDS.
Complications
Scratching the
itchy rash associated with dermatitis can cause open sores, which may become
infected. These skin infections can spread and may very rarely become
life-threatening.
In people with
brown and Black skin, dermatitis might cause the affected area to darken or
lighten (post-inflammatory hyperpigmentation or hypopigmentation). It might
take months or years to return to your usual skin color.
Prevention
While there’s no
known cure for eczema, you can help reduce the occurrence of flare-ups through
the following preventive measures.
1.
Avoid your triggers
The best way you
can prevent an eczema flare-up is to avoid your triggers when possible. These
include any known allergens, as well as sensitivities to chemicals or fabrics.
2.
Avoid dry skin by adopting these habits when
bathing
·
Take shorter baths and showers.
·
Limit your baths and showers to 5 to 10 minutes.
Use warm, rather than hot, water.
·
Bath oil also may be helpful.
· Use a gentle, unscented nonsoap cleansers.
Some soaps can dry your skin.
3.
Dry yourself gently
After bathing,
gently pat your skin dry with a soft towel.
4.
Moisturize your skin
While your skin
is still damp, seal in moisture with an oil, cream, or lotion.
5.
Protect your skin
Protecting your
skin’s barrier with a moisturizing lotion is important, especially after
bathing. Use a lotion that’s free of preservatives and fragrances.
Another way you
can protect your skin is by avoiding the temptation to scratch any eczema
rashes that do develop. This can help prevent cracks and cuts, which can lead
to a risk of infection.
6.
Control the heat and humidity
While eczema
itself can sometimes be dry, this skin condition is typically worsened by heat
and humidity. Consider keeping your home a bit drier and cooler as a way of
managing and preventing flare-ups.
Some people,
however, experience flare-ups during the dry winter months. If this is you,
using a humidifier can help ease your eczema symptoms.
Body heat can
also play a role. Wearing breathable fabrics such as cotton can help heat
escape from your body. Taking cool showers after workouts may also help.
7.
Stress and hormones can also cause flare-ups or
make them worse.
8.
Wear protective clothing if you are doing a task
that involves irritants or caustic chemicals.
9.
If you have open wounds, be sure to protect your
skin with bandages.
Diagnosis
To diagnose
dermatitis, your doctor will likely talk with you about your symptoms and
examine your skin. You may need to have a small piece of skin removed
(biopsied) for study in a lab, which helps rule out other conditions.
Patch testing
Your doctor may
recommend patch testing on your skin. In this test, small amounts of different
substances are applied to your skin and then covered. The doctor looks at your
skin during visits over the next few days to look for signs of a reaction.
Patch testing can help diagnose specific types of allergies causing your
dermatitis.
Treatment
Eczema treatment
has four main goals:
- Control the itch.
- Heal the skin.
- Prevent flares.
- Prevent infections.
The treatment
for dermatitis varies, depending on the cause and your symptoms. In addition to
the lifestyle and home remedies recommendations below, dermatitis treatment
might include one or more of the following:
· Applying to the affected skin certain creams or
ointments that affect your immune system (calcineurin inhibitors)
·
Exposing the affected area to controlled amounts
of natural or artificial light (phototherapy)
·
Using oral corticosteroids (pills) for severe
disease
· Using wet dressings, a medical treatment for
severe atopic dermatitis that involves applying a corticosteroid and wrapping
it with wet bandages.
·
Depending on the cause of your eczema flare-up,
you may need to take oral allergy medications, topical corticosteroid creams,
or both.
·
While steroid creams you apply to your skin are
intended for short-term use, you may need to use allergy medicines you take by
mouth year-round to help prevent associated symptoms.
·
Another option is immunosuppressant drugs, which
slow down immune responses in the case of severe eczema.
·
Antihistamines
Over-the-counter
(OTC) antihistamines may help reduce the incidence of eczema. Pain relievers
like Tylenol or ibuprofen can help you manage your discomfort and inflammation.
Some oral
antihistamines that may be used to treat AD include cetirizine, chlorpheniramine,
diphenhydramine, doxylamine, fexofenadine, loratadine
Additionally, these medications may help
prevent the urge to scratch rashes, especially in children.
·
Allergy shots
For severe
allergies that don’t respond well to medications, a doctor may recommend
allergen immunotherapy, or “allergy shots.” These shots are composed of small
amounts of the substances to which you’re allergic.
Your doctor will
increase your dosage slowly over the course of several months. The idea here is
to help build immunity to your allergen triggers so that you experience fewer
flare-ups overall.
Lifestyle and home remedies
These self-care
habits can help you manage dermatitis and feel better;
·
Moisturize your skin. Routinely applying a
moisturizer can help your skin.
·
Use anti-inflammation and anti-itch products.
Hydrocortisone cream might temporarily relieve your symptoms. Oral
antihistamines, such as diphenhydramine, may help reduce itching. These types
of products are available without a prescription.
·
Apply a cool wet cloth. This helps soothe your
skin.
·
Take a comfortably warm bath. Sprinkle your bath
water with baking soda or a finely ground oatmeal that's made for the bathtub
(colloidal oatmeal). Soak for 5 to 10 minutes, pat dry, and apply unscented
moisturizer while your skin is still damp. A lotion of 12% ammonium lactate or
10% alpha-hydroxy acid helps with flaky, dry skin.
·
Use medicated shampoos. For dandruff, use OTC
shampoos containing selenium sulfide, zinc pyrithione, coal tar, or
ketoconazole.
·
Take a dilute bleach bath. This may help people
with severe atopic dermatitis by decreasing the bacteria on the skin. For a
dilute bleach bath, add 1/2 cup (about 118 milliliters) of household bleach,
not concentrated bleach, to a 40-gallon (about 151-liter) bathtub filled with
warm water. Measures are for a U.S. standard-sized tub filled to the overflow
drainage holes. Soak for 5 to 10 minutes and rinse off before patting dry. Do
this 2 to 3 times a week.
·
Many people have had success using a dilute
vinegar bath rather than a bleach bath. Add 1 cup (about 236 milliliters) of
vinegar to a bathtub filled with warm water.
·
Avoid rubbing and scratching. Cover the itchy
area with a dressing if you can't keep from scratching it. Trim your nails and
wear gloves at night.
·
Choose mild laundry detergent. Because your
clothes, sheets, and towels touch your skin, choose mild, unscented laundry
products.
·
Avoid known irritants or allergens. Try to
identify and remove allergens and other factors in your environment that
irritate your skin. Avoid rough and scratchy clothing.
·
Manage your stress. Emotional stressors can
cause some types of dermatitis to flare. Consider trying stress management
techniques such as relaxation or biofeedback.
·
Oatmeal baths are one type of natural treatment
that can soothe the itchiness and discomfort of eczema rashes. Be sure to use
lukewarm water and follow up with a moisturizer immediately after.
·
There’s some evidence that both probiotics and
prebiotics may stabilize your microbiome to help treat inflammation. However,
more research is needed to support this approach in eczema treatment.
Alternative medicine
Many alternative
therapies, including those listed below, have helped some people manage their
dermatitis. But the evidence for their effectiveness is mixed. And sometimes
herbal and traditional remedies cause irritation or an allergic reaction.
·
Dietary supplements, such as vitamin D and
probiotics, for atopic dermatitis
·
Rice bran broth (applied to the skin), for
atopic dermatitis
·
5% tea tree oil shampoo, for dandruff
·
Aloe, for seborrheic dermatitis
·
Chinese herbal therapy
If you're
considering dietary supplements or other alternative therapies, talk with your
doctor about their pros and cons.
Eczema elimination diet and foods to eat
Foods to eat
For people with
eczema, eating certain foods can trigger the body to release immune system
compounds that cause inflammation, which, in turn, contributes to an eczema
flare-up. An anti-eczema diet is similar to an anti-inflammatory diet.
Examples of
anti-inflammatory foods include:
·
Fish, a natural source of omega-3 fatty acids
that can fight inflammation in the body. Examples of fish high in omega-3s
include salmon, albacore tuna, mackerel, sardines, and herring.
·
Foods high in probiotics, which are bacteria
that promote good gut health. Examples include yogurt with live and active
cultures, miso soup, and tempeh. Other fermented foods and drinks, such as
kefir, kombucha, and sauerkraut, also contain probiotics.
·
Foods high in inflammation-fighting flavonoids.
Examples of these include colorful fruits and vegetables, such as apples,
broccoli, cherries, spinach, and kale.
Eating more of
these foods and cutting down on any trigger foods could help to reduce eczema
flare-ups.
Elimination diet or foods to avoid
Food-sensitive
eczema reactions will typically occur about 6 to 24 hours after a person eats a
particular food. Sometimes, these reactions may be delayed even longer.
To determine
what foods may be causing the reaction, a doctor will often recommend an
elimination diet. This diet involves avoiding some of the most common foods
known to cause eczema.
Before
eliminating any foods, a person will need to slowly add each food type into
their diet and monitor their eczema for 4 to 6 weeks to determine if they are
sensitive to any particular food.
If a person’s
symptoms get worse after adding a particular food to the diet, they may wish to
consider avoiding it in the future. If a person’s symptoms do not improve when
eliminating a food, they probably do not need to remove it from their diet.
Some common
foods that may trigger an eczema flare-up and could be removed from a diet
include;
·
citrus fruits
·
dairy
·
eggs
·
gluten or wheat
·
soy
·
spices, such as vanilla, cloves, and cinnamon
·
tomatoes
·
some types of nuts
People with
dyshidrotic eczema, which typically affects the hands and feet, may experience
benefits from eating foods that do not contain nickel. Nickel is found in trace
amounts in the soil and can, therefore, be present in foods.
Foods that are
high in nickel include;
·
beans
·
black tea
·
canned meats
·
chocolate
·
lentils
·
nuts
·
peas
·
seeds
·
shellfish
·
soybeans
Some people with
eczema also have oral allergy syndrome or sensitivity to birch pollen. This
means they may have reactions to other foods, including green apples, carrots, celery,
hazelnuts, pears
People with
eczema are more prone to oral allergy syndrome and should speak to their doctor
if they have a pollen allergy or experience mild allergic reactions to the
above foods.
Making these
changes and monitoring the results can help a person determine whether changing
their diet can help them better manage their condition.
If a person does
eliminate a large food group, such as wheat-containing products, they may wish
to talk to their doctor about supplements to ensure they are not missing out on
any essential vitamins and minerals.
Eczema and Exercise
The challenge of
enjoying exercise without making your eczema worse can be a delicate balancing
act. How do you avoid overheating, irritation and flare-ups when you’re just
trying to work up a sweat?
The regulation
of body temperature is important for people with eczema. For many of us, being
subjected to quick changes in temperature such as through exercise can bring
about the dreaded skin flare and itch.
Sweat and eczema: controlling that itch
Taking part in
exercise whether it’s a walk on a Saturday morning, a dance class, or an
evening bicycle ride home from work gives the body a workout, and we all sweat
to moderate our temperature. As sweat evaporates, it cools the surface of the
skin.
Perspiration is
largely made up of water together with urea, lactate, and minerals such as
sodium. For people with eczema, exercise can dry out the skin through the loss
of fluids, and the sodium in sweat can further dehydrate the skin as well as
sting and irritate it.
For many people
with eczema, exercise can trigger frenzied scratching as the skin surface
temperature soars. But it doesn’t have to be this way. Being prepared can
counteract many problems early.
Tips for exercising with eczema
·
Drink plenty of water before, during, and after
exercise
No one needs to glug
gallons of water before setting off, but drinking fluids regularly will replace
the water lost when sweating. Anyone with eczema has inherently dry skin and is
susceptible to weaker skin barrier function. Therefore, drinking water
(especially around exercise) to keep the body and skin hydrated is recommended.
·
Carefully consider your clothing options
It’s important
to choose the right clothing to minimize skin irritation as the body heats up.
Synthetic moisture “wicking” clothing options draw sweat into the garments, but
they may feel rough and irritate eczema. Loose-fitting 100 percent cotton
clothing might buck the trend for body-hugging sports clothing, but they are
likely to more comfortable. Mind the edges, too. Synthetics like polyester and
Spandex around the waistline, neckline, or cuffs are best avoided. Ultimately,
of course, it comes down to personal choice. Look for light, breathable fabrics
that don’t rub or scratch the skin during exercise.
·
Respond to your eczema during exercise
Taking regular
breaks during exercise isn’t cheating; it’s an opportunity to rest, rehydrate
and cool down if you’re sensing the start of a flare with your eczema. Being
realistic about the state of your eczema when you want to exercise means
choosing a level of intensity to match.
·
Keep cool
Given the
potential to overheat, bear in mind both surroundings and other ways to slow
the temperature rise. Keep a towel nearby to wipe off sweat during exercise and
exercise in indoor facilities that are well ventilated.
·
Moisturize before and after exercise
In much the same
way that taking on water counteracts water loss while exercising, applying
emollients will protect your skin in advance of and following exercise. A
heavier ointment might feel hot and counterproductive and trap in sweat, so cream
or lighter application of ointment an hour before exercise allows time for it
to have absorbed fully.
·
Just say no to hot showers and baths
There is nothing
quite as satisfying as a hot bath or shower after exercise to relax the muscles
— except, of course if you have eczema. Washing off sweat rather than letting
it dry on the skin is a good idea, but resist the temptation to sizzle under
the shower after a workout. Start with a warm shower and gradually make it
cooler over minutes and in stages.
Gyms, health
clubs, and fitness centers might supply their shower gels and products but use
your products instead. It’s not worth risking a reaction for the sake of
convenience. You can always decant your products into a travel-size container
or get smaller quantities from your physician.
DOs and DON’Ts in Managing Eczema
DO
·
avoid triggers of the rash, including stress.
·
moisturize your skin daily, even when you have
no symptoms. Use an odor-free oil-based cream or ointment (not lotion), best
applied just after bathing while the skin is still damp. Use hypoallergenic
products when possible. For severe itching, also use a very mild
over-the-counter steroid cream (1% hydrocortisone). Bathe with warm, not hot,
water and mild soap.
·
take all pills prescribed by your health care
provider. Don’t stop taking the medicines unless your health care provider
approves.
·
avoid foods that cause your eczema to worsen.
·
exercise daily, but avoid excessive sunlight
exposure and skin damage with a sunblock (SPF 15 or greater).
·
wash clothing and linens in fragrance-free soap;
double rinse when possible.
·
call your health care provider if you have signs
of infection (worsening redness, pus); wheezing or trouble breathing; or a
severe stomachache or bone pain when taking steroid pills.
DON’T
·
let your skin or home become too dry. A home
humidifier may help.
·
forget your daily skin regimen even if you feel
well. Plan ahead for trips by saving some of your usual products.
·
drive, cook, or operate machinery while using
antihistamines if they make you sleepy.
Frequently asked questions (FAQs)
·
Does
eczema go away?
There’s no known
cure for eczema, and the rashes won’t simply go away if left untreated. For
most people, eczema is a chronic condition that requires careful avoidance of
triggers to help prevent flare-ups.
Age is also
thought to play a role, about 60 percent of people who have eczema develop it
as infants. If you develop eczema as a child, then you may experience improved
symptoms as you get older.
·
How long
do eczema flare-ups last?
The healing time
from eczema ultimately depends on the underlying cause.
If you have a
flare-up from a contact eczema trigger, the rash will likely go away within a
few weeks upon treatment. (A contact eczema trigger is a substance that brings
on a flare when it comes in contact with your skin.)
Allergic
triggers may result in longer-lasting flares.
Takeaway
For most people,
eczema is a lifelong condition that consists of occasional flare-ups.
Once treated, it
can take several weeks for rashes to clear up. Since these rashes develop from
negative immune reactions, there’s also a risk that more flare-ups will occur
unless you reduce your exposure to triggers.

Kaosara.
