What cause asthma and allergies

You are likely to experience these symptoms if animal dander gets to your lungs. However, you need to be aware of other symptoms too. For example, you might only experience allergic-type symptoms such as a runny or stuffy nose. Likewise, you might experience a scratchy throat or watery, itchy eyes.

Finally, if you get scratched you might experience redness on the impacted area or symptoms on an area you self-inoculate (if you touch the area that was scratched or licked and rub it with a hand and then touch your hand to your nose or eyes).

If you are not terribly sensitive or you are not exposed to large amounts of dander, your reaction could happen days later making it more hard to link the pet exposure to symptoms.


What are the causes of asthma?

The exact cause of asthma is unknown and the triggers can vary from person to person.

However, it is recognised that asthma runs in families (if a parent or sibling has asthma, you’re more likely to own it too) and that environmental factors can frolic a part.

Asthma often occurs as the result of an immune system response to an environmental allergen, such as pollen or dust mites.

What cause asthma and allergies

Not everyone exposed to the same allergen reacts to it, or may react differently. Although the reasons why a specific allergen affects one person more than others isn’t entirely clear, it’s possible that inherited genes may be involved.

Some risk factors that can increase your chances of developing asthma include:

  1. Having had bronchiolitis (a lower respiratory tract infection) as a child
  2. Having an allergy, such as hay fever, eczema or a food allergy (these are known as atopic conditions)
  3. Being a smoker
  4. Being exposed to secondhand or passive smoke, including during childhood or pregnancy
  5. Having a family member, such as a parent or sibling, who has asthma
  6. Being born prematurely or with a low birthweight.

Asthma triggers

The airways to the lungs are normally open, allowing air to move freely in and out of the lungs.

However, people who own asthma own sensitive airways that are irritated and inflamed. Asthma symptoms are caused when the airways tighten or constrict in response to triggers, resulting in less space in the airways to breathe through.

The symptoms of asthma can be triggered by various irritants, substances and circumstances. The known triggers of asthma include:

  1. Physical activity, especially if doing so in freezing and dry weather
  2. Allergic reactions, such as to dust mites, animal fur, feathers or pollen
  3. Experiencing strong emotions such as stress
  4. Taking medicines, such as anti-inflammatory painkillers
  5. Respiratory infections such as colds or flu
  6. Being exposed to damp or mould
  7. Exposure to smoke, pollution or fumes
  8. Sulphites and preservatives added to some foods and beverages, including dried fruit, shrimp, processed potatoes, beer and wine
  9. Changes in weather, including freezing air, thunderstorms, heat, humidity or any sudden change in temperature
  10. Gastroesophageal reflux disease (GERD), where stomach acid comes back up into your throat.

If you’re aware what your potential triggers are you should attempt to avoid them, where possible, to assist control your asthma.


Asthma treatment and medicines

Asthma treatment and medicines assist to control symptoms, so you can live an athletic and normal life.

As everyone experience asthma differently, your doctor will put together an asthma treatment plan designed specifically for you.

The two types of inhalers that are used to relieve and prevent asthma are:

  1. Preventer inhaler – this contains steroid medicine and is used daily, as prescribed, to reduce the quantity of inflammation and sensitivity in your airways.

    What cause asthma and allergies

    It will assist stop asthma symptoms occurring and is normally brown.

  2. Reliever inhaler – this is used to treat your symptoms when they happen and generally works within minutes. The inhaler is normally blue.
  3. Nian-Sheng Tzeng1, Hsin-An Chang1, Chi-Hsiang Chung1, Yu-Chen Kao1, Chuan-Chia Chang1, Hui-Wen Yeh1, Wei-Shan Chiang1, Yu-Ching Chou2, Shan-Yueh Chang1 and Wu-Chien Chien1*. Increased Risk of Psychiatric Disorders in Allergic Diseases: A Nationwide, Population-Based, Cohort Study.

    Frontiers in Psychiatry, 2018 DOI: 10.3389/fpsyt.2018.00133

Depending on your symptoms, tablets or other treatments may also be prescribed. Complementary therapies, such as special breathing exercises, may be recommended to assist you study to breathe better with asthma and increase your overall lung capacity, strength and health.

Patients with asthma and hay fever own an increased risk of developing psychiatric disorders, finds a new study published in open-access journal Frontiers in Psychiatry.

Almost 11% of patients with common allergic diseases developed a psychiatric disorder within a 15-year period, compared to only 6.7% of those without — a 1.66-fold increased risk. While previous studies own linked allergies with certain psychiatric or emotional disorders, this is the first to discover a connection between common allergies and the overall risk of developing psychiatric disorders. The findings could own implications for how doctors care for and monitor patients with allergic diseases.

Asthma, allergic rhinitis (hay fever) and atopic dermatitis (eczema), are among some of the most common allergic diseases and are nicknamed the three «A»s.

Dr. Nian-Sheng Tzeng , from Tri-Service General Hospital in Taiwan and lead author of the study, noticed something unexpected about these patients.

«As a clinician, I observed that some patients with the three ‘A’s appeared to suffer emotionally,» says Tzeng. «Therefore, I wanted to clarify whether these allergic diseases are associated with psychiatric disorders.»

When Tzeng and colleagues searched the literature, they found that previous studies had reported links between allergic diseases and specific psychiatric disorders or emotional problems. For example, a study in Denmark found that children with allergic diseases had more emotional and behavioral problems.

However, not every previous research supported this positive link, with one study in Taiwan suggesting that allergic rhinitis is less common among patients with schizophrenia, for example.

What cause asthma and allergies

Clearly, more extensive research was needed for a more finish picture.

Despite the previous research, no-one had studied the link between the three «A»s and the overall risk of developing psychiatric disorders. To study this in a large sample of people, the researchers used an extensive database of health insurance claims in Taiwan, covering a 15-year period.

The researchers identified 46,647 people in the database with allergic diseases and 139,941 without. Unlike previous studies, the researchers included patients of every ages. They found that over the 15-year period, 10.8% of people with allergic diseases developed a psychiatric disorder, compared with 6.7% of those with no allergic disease.

This translated to a 1.66-fold increased risk of developing psychiatric disorders for people with an allergic disease.

A closer glance at the data revealed that people with atopic dermatitis had a lower risk of developing a psychiatric disorder, while those with asthma and allergic rhinitis had a higher risk. Interestingly, the team discovered that using certain asthma medications was associated with a lower risk of psychiatric disorders in asthma patients.

So, why might patients with certain allergic diseases own a higher risk of psychiatric disorders?

Recent research suggests that inflammation is linked to psychiatric disorders, such as depression and anxiety disorders. As allergies also involve inflammation, it is possible that it may contribute to psychiatric disorders in the same patients. The psychological stress of a psychiatric disorder might also contribute to physical symptoms.

The current study did not examine the potential cause of this phenomenon and researchers need to finish further studies to identify the precise mechanisms involved. However, knowing that there is a link between allergic diseases and psychiatric disorders could assist doctors to care for their patients.

«We would love to let clinicians who care for patients with allergic diseases know that their risk for psychiatric diseases may be higher,» says Tzeng.

«Assessing their emotional condition and monitoring their mental health could assist to avoid later psychiatric problems.»

How do you diagnose allergic rhinitis?

Your doctor will confirm the specific allergens causing your rhinitis by taking a finish symptom history, doing a physical examination, and performing skin prick tests.

What is the impact?

About 20 per cent of the general population suffers from rhinitis. Of these people, about one third develops problems before the age of 10.

The overall burden of allergic rhinitis is better understood when you consider that 50 per cent of patients experience symptoms for more than four months per year and that 20 per cent own symptoms for at least nine months per year.

Those affected by hay fever suffer more frequent and prolonged sinus infection, and for those who also own red, itchy eyes, there is the risk of developing infective conjunctivitis due to frequent rubbing.

Persistent symptoms and poor quality sleep can result in lethargy, poor concentration and behavioural changes and impact on learning in young children.
Allergic rhinitis may predispose people to obstructive sleep apnoea, due to the upper airways collapsing during sleep.

This results in reduced airflow, a drop in oxygen levels and disturbed sleep.

Patients with allergic rhinitis also suffer from more frequent and prolonged respiratory infections, and asthma has been shown to be more hard to control unless allergic rhinitis is also managed.

What are the symptoms?

Symptoms of allergic rhinitis can be any combination of itching in the back of the throat, eyes or nose, sneezing, runny eyes or nose, and blocked nose.

A person may own any or every of the following:

  1. dizziness or nausea related to ear problems
  2. frequent throat-clearing
  3. bouts of sneezing, especially in the morning
  4. repeated nosebleeds
  5. breathing through the mouth
  6. a horizontal crease across the nose as a result of constant rubbing
  7. watery discharge from the nose every the time, occasionally or during certain seasons of the year
  8. chronic freezing without much fever
  9. rabbit-like movements of the nose
  10. headaches because of pressure from inside the nose
  11. snoring
  12. nasal voice because of blocked nasal passages
  13. stuffy nose every the time or during specific seasons
  14. reddened, pebbly lining in the lower eyelids
  15. frequent earaches, fullness in the ear, ear infections or hearing loss
  16. dark circles under the eyes as a result of pressure from blocked nasal passages on the little blood vessels.

    Also known as "allergic shiners".

What causes allergic rhinitis?

The most common triggers for people with allergic rhinitis are pollen, dust mite, pet and mould allergens.

Seasonal allergic rhinitis (hay fever) is generally triggered by wind-borne pollen from trees, grass and weeds. Early spring symptoms point to tree pollen, while nasal allergy in tardy spring and summer indicates that grass and weed pollens are the culprits. And overlapping the grass season is the weed pollen season, which generally starts in tardy spring and extends through to the finish of summer.

In New Zealand the seasons are not extremely distinct and they vary throughout the country because of the diverse climates.

The season starts about one month earlier at the top of the North Island than the bottom of the South Island. Thus the hay fever season is not extremely well defined.

Allergic rhinitis that persists year-round (perennial allergic rhinitis) is generally caused by home dust mites, pets, or mould. People with allergic rhinitis are often allergic to more than one allergen, such as dust mite and pollen, so may suffer from symptoms for months on finish or every year round.

Irritants such as strong perfumes and tobacco smoke can aggravate this condition.

Foods do not frolic as large a role as had been thought in the past.

What is the link between allergic rhinitis and asthma?

Allergic rhinitis has been found to be an extremely common trigger for asthma in both children and adults.

Allergic rhinitis can also exacerbate asthma, and it can make the diagnosis of asthma more difficult.

Around 80 per cent of people with asthma suffer from allergic rhinitis, and around one in four with allergic rhinitis has asthma.

There is now extremely excellent evidence to support the thought that asthmatics who glance after their upper airways well need less asthma medication and fewer hospital or GP visits.

When treating both asthma and allergic rhinitis, the first step is to discover out the cause of your problem.

Once the causes own been identified, management regimes can be put into put to minimise the impact of the allergy, and this then reduces the need for medication.

When does allergic rhinitis develop?

Allergic rhinitis typically develops in childhood. It is part of what we call the Allergic March, where children first develop eczema in infancy, sometimes followed by food allergy, and then go on to develop allergic rhinitis and then asthma.

The onset of dust mite allergy occurs often by the age of two, with grass pollen allergy beginning around three to four years of age. Tree pollen allergy develops from about seven years of age.

It is not unusual to develop hay fever during adulthood.

It can take as few as two to three seasons to become sensitised to pollen, but it depends on the individual.

Asthma treatment and medicines

Asthma treatment and medicines assist to control symptoms, so you can live an athletic and normal life. As everyone experience asthma differently, your doctor will put together an asthma treatment plan designed specifically for you.

What is allergic rhinitis?

Hay fever is the common name to describe allergic rhinitis and involves a recurrent runny, stuffy, itchy nose, and frequent sneezing.

It can also affect your eyes, sinuses, throat and ears.

Love any other allergy, allergic rhinitis is an inappropriate immune system response to an allergen – most commonly home dust mite, pet, pollen and mould. The allergen comes into contact with the sensitive, moist lining in your nose and sinuses and sets off the allergic response.

Hay fever is often considered a nuisance rather than a major disease and most people will self-treat. However, recent studies own revealed that hay fever has a huge impact on quality of life.

How is allergic rhinitis treated?

It is useful to identify your triggers and attempt and avoid them.

This can be difficult.

Pets: Make certain you hold it exterior and never let it in the bedroom. It is never simple trying to decide on a new home for a pet, but in some cases this might be the best option. Even after you own removed your pet from your home, the allergens remain in furnishings for endless periods afterwards and can cause symptoms. You will need to thoroughly clean your walls, floors and carpets to remove the allergen.

Dust mites: Home dust mite reduction measures include mite-proof covers for the mattress, duvet and pillows. Removing items that collect dust from the bedroom will assist. A excellent quality vacuum cleaner with HEPA filter for the exhaust air is essential to ensure that allergen is not disseminated in the atmosphere.

Bedding should be washed frequently in water hotter than 55ºC. If you own soft toys, freeze them overnight and air in the sun.

Pollen: It is hard to avoid pollen, however you can avoid going exterior when pollen counts are high. The quantity of pollen in the air is highest:
• In the morning
• Outside
• On windy days
• After a thunderstorm

See our pollen calendar for more information.

Medication

Non-sedating antihistamine tablets or liquid are useful in alleviating some of the symptoms of rhinitis.

They are helpful in controlling sneezing, itching and a runny nose, but are ineffective in relieving nasal blockage. They can be used alone or in combination with other medications, such as nasal sprays.

Corticosteroid (anti-inflammatory) nasal sprays reduce the inflammation in the lining of the nose. They work best when used in a preventative manner, just love preventers for asthma. For example, they may be used for weeks or months at a time during an allergy season. Enquire your doctor about the appropriate medication for your condition.

Decongestant nasal sprays can be used to unblock the nose, but should not be used for more than a few days at a time.

Prolonged use may result in worsening of the nasal congestion.

Eye drops: The eye problems that sometimes happen with allergic rhinitis may not always reply to the above medications. Eye drops containing decongestants alone or in combination with antihistamine are available for mild to moderate eye problems. Eye irritation is one side effect. Prolonged use of decongestant eye drops can also cause rebound worsening when stopped. Some brands of eye drops can be used preventatively and are safe to use for prolonged periods — enquire your doctor for more specific information.

Saline washes may assist to clear your nose and soothe the lining of your nose.

These are available from most pharmacies.

Desensitisation, or immunotherapy, is used to 'turn off' the abnormal response of the immune system to an allergen if medication does not work. It is mainly used to relieve the symptoms of hay fever and allergic asthma to pollen, mould, home dust mite and pet allergen, as well as to control severe reactions to insect stings.

To start, a extremely dilute dose of the substance you are allergic to is istered by injection once or twice a week.

This dose is gradually built up over three to four months on average, until a maintenance dose is achieved. Shots are then given monthly for at least three years.

This method of treatment is the only one that deals with the underlying cause of allergic rhinitis. Not everyone benefits from treatment, however the vast majority of patients show at least some degree of improvement. Enquire your allergy specialist about whether you are a excellent candidate for immunotherapy.

Sublingual immunotherapy is another method, where drops of the allergen solution are taken under the tongue.

It is not widely used exterior of Europe.

You may own heard that "animal dander" from your pet(s) may worsen your asthma. In fact, every furry/feathered animals produce animal dander. Thus, any pet dander puts asthmatics at an increased risk of poor asthma control if they are sensitive.

This is not a little problem.

According to the Asthma and Allergy Foundation of America, as numerous as 30% of every asthmatics own an allergy to dogs or cats. While numerous people associate asthma-related symptoms with hair, it is actually the dander causing problems.

You may own heard that "animal dander" from your pet(s) may worsen your asthma. In fact, every furry/feathered animals produce animal dander. Thus, any pet dander puts asthmatics at an increased risk of poor asthma control if they are sensitive.

This is not a little problem.

According to the Asthma and Allergy Foundation of America, as numerous as 30% of every asthmatics own an allergy to dogs or cats. While numerous people associate asthma-related symptoms with hair, it is actually the dander causing problems.


What Animal Dander Is

While it is commonly thought that it is the hair from pets that causes the allergic cascade leading to asthma symptoms and short-haired animals are less allergic for asthmatics, both are myths. In fact, it is dander or the proteins in skin flakes, urine, feces, saliva and hair that trigger your asthma symptoms.

These proteins are extremely little particles that are carried through the air and can come to land on a body part that comes into contact with your nose or mouth (like your finger) or the particles can be directly inhaled into the lung. You may notice symptoms immediately or may not develop them for 8 to 12 hours.


Types of asthma

Unlike some other health conditions, there’s no single form of asthma – it affects diverse people in diverse ways.

As knowledge and understanding of asthma has improved over the years, medical experts own identified various types of asthma.

Knowing which type of asthma you own can assist you study how to manage it more effectively and reduce the risk of coming into contact with known asthma triggers.

Adult-onset asthma

Adult-onset asthma is so-called as it starts in adulthood, rather than childhood. It’s sometimes referred to as late-onset asthma. Adult-onset asthma can be caused by occupational and environmental factors, female hormones, smoking and stressful life events.

Occupational asthma

Occupational asthma is caused by your occupation or work.

It’s often associated with allergic asthma and can be triggered by exposure to fumes, chemicals, dust or other triggers you encounter on a regular basis during the course of your work.

Exercise-induced asthma

In some cases, asthma can be triggered by physical exertion and is called exercise-induced asthma. Asthma symptoms can get worse both during and after exercising.

Non-allergic asthma

Non-allergic asthma, or non-atopic asthma, is a form of asthma that isn’t triggered by an allergy.

This type of asthma often starts later in adulthood.

Seasonal asthma

Seasonal asthma only occurs at certain times of the year. Symptoms may flare up in the summer when pollen levels are high, or in the winter when the weather is extremely cold.

Childhood asthma

Childhood asthma is common and first occurs during childhood. Sometimes this type of asthma can get better or even vanish completely as you get older, although it can also return during adulthood.

Allergic asthma

Allergic, or atopic asthma, is a type of asthma triggered by allergens, such as pollen, dust mites, pet fur or feathers. If you own allergic asthma, you’ve got a higher chance of also having other forms of allergies, such as hay fever, food allergies or eczema.

Difficult asthma

Difficult asthma is a type of asthma that’s hard to manage and control.

The symptoms are more likely to continue, despite treatments, and frequent asthma attacks are common.

Severe asthma

Severe asthma affects people intensely and can own a major impact on daily life. You’re more likely to own severe asthma if your symptoms are ongoing despite being prescribed higher doses of inhaled steroids or other medications, and you may need long-term steroid tablets.


Asthma diagnosis

If your doctor suspects you could own asthma, they’ll enquire about your symptoms and undertake tests to diagnose it. They’ll glance at your nose, throat and upper airways, hear to your breathing using a stethoscope and take a general medical history.

Lung function tests will be carried out to see how well your lungs work.

Common tests used include:

  1. Spirometry – where you blow into a machine that measures how quick you can breathe out and how much air you’re capable to hold in your lungs.
  2. Peak flow test – where you blow into a little handheld device and it measures how quickly you can breathe out.
  3. FeNO test – where you breathe into a machine that measures the level of nitric oxide in your breath (this can highlight inflammation in your lungs).

In some cases, you may own a chest x-ray to law out other causes of your symptoms.

Depending on the results of your tests, your asthma will be classified into one of four general categories:

Asthma classification Signs and symptoms
Mild intermittent Mild symptoms up to two days a week and up to two nights a month
Mild persistent Symptoms more than twice a week, but no more than once in a single day
Moderate persistent Symptoms once a day and more than one night a week
Severe persistent Symptoms throughout the day on most days and frequently at night


What are the symptoms of asthma?

Some of the common signs and symptoms of asthma include:

  1. Shortness of breath
  2. Attacks of coughing and wheezing that are made worse when you own a freezing, flu or other respiratory illness
  3. A whistling or wheezing sound when you exhale (wheezing is especially common in children with asthma)
  4. A feeling of pressure, tightness or pain in your chest
  5. Coughing
  6. Trouble sleeping at night due to being short of breath, coughing or wheezing.

Not everyone who has asthma has exactly the same symptoms and diverse symptoms may happen at diverse times  of the year and at diverse times during your life.

Symptoms can also vary from mild to more severe.

If your asthma is changing or flaring up, then you may discover symptoms become worse than usual. You may discover it more hard to breathe, experience more wheezing and need to use a quick-relief inhaler more often.

What happens during an asthma attack?

When an asthma attack occurs, the muscles around the airways will first tighten – this is called a bronchospasm. A bronchospasm makes your chest feel tight and makes it harder to catch your breath. You may make a whistling sound when you attempt to breathe, or start wheezing. The lining in the airways will become inflamed and swollen, more mucus will be produced, plus the mucus will be thicker than usual.

If you own mild asthma, taking your reliever inhaler should start to assist the attack within minutes.

But if you own more severe asthma, you may need medical attention, as it can be life-threatening.

Early warning signs of an asthma attack

Asthma is a long-term chronic condition, but when an asthma attack happens, it’s an acute occurrence. This means it’s a sudden attack that happens for someone suffering with a chronic condition.

There are some early warning signs that you can glance out for that may propose an asthma attack is likely. The symptoms are generally mild, but can be useful to recognise so that you can do your best to prevent a full-blown asthma attack.

The early warning signs and symptoms to glance out for include:

  1. Shortness of breath
  2. A decrease in your usual lung function (which can be measured by using a peak flow metre)
  3. Having a frequent cough, especially if it’s worse at night
  4. Extreme tiredness when exercising
  5. Wheezing and coughing after exercising
  6. Allergies or a freezing, including nasal congestion, sneezing, sore throat and a headache.

If you own a personal asthma action plan in put, then you could adjust your medication in line with these early warning signs.

If you don’t own an action plan, or you own the symptoms of an asthma flare-up, enquire your doctor for advice.
