Q : What Is The Scratch And Itch Cycle Of Eczema
The scratch and itch cycle of eczema can cause discomfort, disrupt sleep and affect quality of life:
- In people with eczema the skin does not retain moisture very well, which causes it to dry out easily.
- This makes the skin more open to allergens and irritants, which can trigger the skin to release chemicals that make the skin itchy.
- Scratching itchy skin causes more chemicals to be released, making the skin feel itchier.
- If eczema is well managed this can avoid the scratch and itch cycle. It is therefore important to keep skin that is prone to eczema well moisturised, by using moisturising creams on the skin every day.

When To Seek Medical Advice
See a GP if you have symptoms of atopic eczema. They’ll usually be able to diagnose atopic eczema by looking at your skin and asking questions, such as:
- whether the rash is itchy and where it appears
- when the symptoms first began
- whether it comes and goes over time
- whether there’s a history of atopic eczema in your family
- whether you have any other conditions, such as allergies or asthma
- whether something in your diet or lifestyle may be contributing to your symptoms
Typically, to be diagnosed with atopic eczema you should have had an itchy skin condition in the last 12 months and 3 or more of the following:
- visibly irritated red skin in the creases of your skin such as the insides of your elbows or behind your knees at the time of examination by a health professional
- a history of skin irritation occurring in the same areas mentioned above
- generally dry skin in the last 12 months
- a history of asthma or hay fever children under 4 must have an immediate relative, such as a parent, brother or sister, who has 1 of these conditions
- the condition started before the age of 2

What Doesnt Cause Eczema
Eczema is not contagious. You can’t catch eczema by coming in contact with someone who has it.
Eczema is not an allergic reaction. Even so, a large number of children who have eczema also have food allergies. That doesn’t mean that certain foods such as dairy, eggs, and nuts — common food allergy triggers in children with eczema — cause it or make it worse. Before removing particular foods from your child’s diet, talk with your doctor to be sure your child’s nutritional needs will be met.
Key Points About Atopic Dermatitis
- Atopic dermatitis is commonly called eczema.
- Its an inherited and chronic skin disorder that is most common in infants or very young children.
- Atopic dermatitis causes dry, scaly, red skin that has red bumps that open and weep when scratched.
- Its important to find and avoid things that make atopic dermatitis worse. Triggers include stress, high or low temperatures, bacterial infections, fabrics such as wool, and detergents.
- The goals of treatment are to reduce itching and inflammations of the skin, to keep the skin moisturized, and prevent infection.

Some People Use Too Much
Only use topical steroids for eczema as directed by your doctor. Some people continue to use topical steroids each day in the long term after the eczema has cleared to ‘keep the eczema away’. This is not normally needed. Some people with severe eczema may require continuous steroid treatment. However, this should be under the close supervision of a doctor. All people with eczema should use moisturisers every day to help prevent further flare-ups of eczema.
Does Eczema Go Away
Theres no known cure for eczema, and the rashes wont 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 developing it as infants. If you develop eczema as a child, then you may experience improved symptoms as you get older.

Some People Use Too Little
A common mistake is to be too cautious about topical steroids. Some parents undertreat their children’s eczema because of an unfounded fear of topical steroids. They may not apply the steroid as often as prescribed, or at the strength needed to clear the flare-up. This may actually lead to using more steroid in the long term, as the inflamed skin may never completely clear. So, you may end up applying a topical steroid on and off for quite some time. The child may be distressed or uncomfortable for this period if the inflammation does not clear properly. A flare-up is more likely to clear fully if topical steroids are used correctly.
Eczema Linked To Potential For Other Health Problems
A groundbreaking new guideline from the American Academy of Dermatology highlights a range of health issues that may be related to this skin condition including hay fever, asthma, osteoporosis, and depression.

People with atopic dermatitis, commonly known as eczema, may find that inflammation of the skin is just one of the health conditions theyre living with.
Dermatologists have been aware of an association between eczema and other health concerns. Now, after evaluating data from numerous studies, the American Academy of Dermatology has produced an official guideline, which was released at the beginning of the year.
The analysis, published in the Journal of the American Academy of Dermatology in January, found strong evidence tying atopic dermatitis in adults to a number of diseases and conditions, including hay fever, asthma, and food allergies alopecia and chronic urticaria osteoporosis mental health disorders like depression and skin infections.
When it comes to substance abuse disorder, ADHD , and metabolic syndrome , study authors identified some evidence linking these issues to eczema.
The report also suggested a link between atopic dermatitis and various cardiovascular issues, but this association was considered to be small. Evidence supporting a link between eczema and autism spectrum disorders, heart attack, and stroke was inconclusive.

Q : What Triggers Should Be Avoided
People with eczema should avoid known triggers and irritants, which may include:
- Dry skin – this is one of the main triggers of eczema.
- Scratching – keep fingernails clipped .
- Viral or bacterial infections.
- Playing in sand, such as sandpits.
- Sitting directly on carpets or grass.
- Inhaling pollen allergens from grasses, weeds or trees in spring and summer.
- Irritants such as perfumes, soap and chemicals.
- Contact with animals, house dust mite allergen, wool and synthetic fabrics.
- Temperature changes, such as overly heated rooms.
- Stress, which can make eczema worse, although eczema is not a psychological condition.
- Constant exposure to water or chemicals, which can damage the protective barrier function of the skin.
What Are The Symptoms Of Atopic Dermatitis
The area of the body affected by atopic dermatitis may change with age. In infants and young children, it usually affects the face, outside of the elbows, and on the knees. In older children and adults, it tends to be on the hands and feet, the arms, on the back of the knees, and the folds of the elbows.
Symptoms are slightly different for each person. Common symptoms include:
- Dry, scaly patches on the skin
- Small bumps that open and weep when scratched
- Redness and swelling of the skin
- A thickening of the skin
- Scratch marks on the skin
Too much rubbing and scratching can tear the skin and lead to infection.
The symptoms of atopic dermatitis may look like other skin conditions. Always talk with your healthcare provider for a diagnosis.

Eczemas Link To Depression And Substance Abuse Disorders
An analysis that pooled four studies, including 11,244 adults with eczema and 149,713 people without the condition, found that individuals with eczema faced double the odds of self-reported or clinician-diagnosed depression. In addition, researchers found that eczema patients were more likely to consider suicide, but evidence linking the condition to actual death by suicide was weak.
As to why these patients may be more apt than the general public to have mental health issues, the AAD panel believes that itching, poor sleep, and decreased quality of life overall may play an extensive role.
Although some research made a connection between substance abuse and eczema, evidence was limited about any tie between the skin condition and alcohol use or cigarette smoking.
Davis and her collaborators underscored that ADHD and autism spectrum disorders are better studied in children rather than adults, and these connections will be explored more in depth in an upcoming pediatric guideline.
What Are The Symptoms Of Ad
Itching is the hallmark of AD, with some data showing that more than 85% of people with the condition experience this distressing symptom every day. Sore or painful skin and poor sleep caused by itching are also common.
People with AD can get rashes anywhere on the body that can ooze, weep fluid and bleed when scratched, making skin vulnerable to infection. Skin can become dry and discolored, and repeated scratching can cause thickening and hardening a process called lichenification.

Q : How Can Skin Be Maintained And Protected Every Day
It is important to keep skin that is prone to eczema well moisturised every day:
- Moisturisers add moisture and form a barrier that protects the skin, so that it retains moisture. If the protective barrier of skin is damaged eczema frequently develops.
- Apply non-perfumed moisturiser to the face and body twice every day.
- Avoid moisturisers containing food proteins such as goat milk, wheatgerm and nut oils.
- After a bath or shower in lukewarm water, pat the skin dry and apply moisturiser.
- Use non-soap based wash or oil and avoid soap and bubbly products which dry out the skin.
- After swimming , rinse and apply moisturiser.
Managing Your Work Life With Eczema
Eczema can affect how, when, and where you work. About 15 percent of the workday can be impacted by symptom flare-ups on average, according to a study published in August 2018 in JAMA Dermatology.
Regardless of disease severity, people with the disease are more likely to take five or more days off work each year compared with their coworkers not affected by eczema. For some people, that can mean having to work from home or otherwise have special accommodations at work, such as avoiding contact with irritating chemicals, notes the NEA.
You may need a doctors note for your employer, something that Yu says he has written for patients. Clearly communicate what you need and why so you can navigate work with eczema successfully.

How Is Eczema Diagnosed What Tests Are Done
Your healthcare provider will take a close look at your skin. They will look for classic signs of eczema such as a redness and dryness. They will ask about the symptoms youre experiencing.
Usually your healthcare provider will be able to diagnose eczema based on examining your skin. However, when there is doubt, they may perform the following tests:
- An allergy skin test.
- Blood tests to check for causes of the rash that might be unrelated to dermatitis.
- A skin biopsy to distinguish one type of dermatitis from another.
Asthma Allergies And Hay Fever
These conditions tend to be closely connected with eczema. Your risk of eczema is higher if you or someone in your family has one or more of these conditions. More than half of kids with eczema will get these conditions by age 13, and they can stick around for the rest of their lives.
With asthma, you may have trouble breathing sometimes or need regular treatment for frequent asthma attacks. Also called allergic rhinitis, hay fever is when pollen, dust mites, pet dander, and other allergens inflame your nose and sinuses. The condition causes:
- Itching and swelling of the nose, mouth, eyes, and skin
- A stuffy or runny nose

Q : How Is Eczema Related To Food Allergy
Whilst food allergy can trigger or worsen eczema symptoms in some people, food allergy is rarely the cause of eczema. Most food allergy causes hives , vomiting and irritability within 30 minutes of eating the offending food. Food allergy only occasionally triggers delayed eczema flare ups.
Many babies with moderate or severe eczema will also have a food allergy. In some babies with severe eczema, short term removal of certain food/s using a medically supervised elimination diet may result in better eczema control. An elimination diet should be supervised by a clinical immunology/allergy specialist , in association with a dietitian with specialised knowledge of food allergies.
If there is no improvement in two weeks on the elimination diet, it means that food is unlikely to be the cause of the eczema. If the skin improves, foods are introduced one at a time as a medically supervised food challenge, to confirm which food causes the eczema to flare.
If food allergy is not the cause of eczema, removal of the food/s will not reduce symptoms.
Children with eczema and/or food allergy can have false positive allergy tests, and this can lead to unnecessary removal of foods which may affect growth and development. Removal of foods may also increase the risk of developing allergy to those foods. Therefore, allergy test results should always be interpreted by a clinical immunology/allergy specialist.
What Is It Like Living With Eczema
Many people live with eczema . As many as 15 million Americans may have this skin condition. Living with it can be challenging.
There may be times when your eczema disappears. This is known as a remission period. Other times you may have a flare-up, which is when it gets worse. The goal of treatment is to prevent such flare-ups, preventing your symptoms from getting worse. Be sure to avoid triggers, moisturize, take your medicine and do anything else your healthcare provider recommends.

Why Is The Long
Data about the long-term course of AD are necessary for informing clinicians and patients about prognosis and guiding treatment decisions at an individual level and for planning at the health systems level. Traditionally, AD was considered a pediatric condition and families were told most children outgrow AD by adolescence. Such imprecise information is insufficient for patients who desire detailed prognostic data. Moreover, it is insufficient for understanding the impact of potentially disease-modifying interventions, a topic of particular salience in the current era of systemic drug development.
Study Design And Setting
We undertook a cohort study with data from the UK Clinical Practice Research Datalink , linked to Hospital Episode Statistics inpatient data, Office for National Statistics mortality data, and index of multiple deprivation data. CPRD is a database of prospectively collected primary care records from general practitioners using Vision software approximately 9% of the UK population are represented in the database.1011 Data are anonymised and include diagnoses , prescriptions , and referrals to specialists. Approximately 80% of CPRD practices registered in England have consented to their patients primary care records being linked to other data sources. Hospital Episode Statistics include all NHS inpatient hospital stays in England since 1997, with diagnoses coded using ICD-10 codes and procedures coded according to OPCS Classification of Interventions and Procedures codes. Office for National Statistics linked mortality data contain the underlying cause of death, recorded on the death certificate, along with up to 15 other recorded causes of death. Causes are coded using ICD-9 codes before January 2001 and ICD-10 codes thereafter. Index of multiple deprivation data contain quintiles of deprivation based on the patients postcode. For this study, data were extracted from the January 2016 CPRD build and the Set 12 linked data.
