Allergy Testing Ottawa

Allergy Testing Ottawa - Asthma literally translates to and means "panting" in the Greek language. It refers to a chronic inflammatory illness of the lungs and airways. The characteristic asthma symptoms are recurring and variable, comprising reversible airflow obstruction and bronchospasm. Indications of asthma comprise: chest tightness, wheezing, coughing and shortness of breath. Asthma is clinically classified depending on the frequency of indications, peak expiratory flow rate and forced expiratory volume in one second. Asthma can be further categorized as atopic or extrinsic or non-atopic or intrinsic.

The condition of asthma is triggered by several environmental and genetic factors or combination there of. Acute symptoms are normally treated by using an inhaled short-acting beta-2 agonist like for example salbutamol. People who have asthma try to avoid triggers including irritants and allergens. People who have asthma normally find relief by inhaling corticosteroids. Treatments making use of Leukotriene antagonists are less helpful as opposed to corticosteroids are normally less favored.

Usually, a diagnosis is made based upon the pattern of signs in addition to the response to therapy over time. Ever since the 1970s, there has been a considerable increase in asthma. According to the 2010 statistics, all around the world, over 300 million people are affected worldwide and 250,000 asthma deaths were recorded in 2009. The prognosis for asthma is generally good because of the ability to proper handle this particular condition through therapy.


The classification of asthma is based upon its seriousness in individuals, the frequency of indications, if the symptoms take place at night, predicted percent of FEV1 and FEV1 variability, how often and intermittent the attacks occur. The asthma could be considered mild persistent if the attacks take place less than twice a week and not daily. Like for instance, if they happen 3 to 4 times per month. One more category will be moderate persistent. These attacks can occur once a week but not nightly. Daily attacks are considered to be severe persistent happening normally 7 times in a week, maybe several times per day.

Currently, there is no concise way for categorizing various subgroups of asthma, even if the condition is classified based on severity as listed above. Cases of asthma respond to different treatments. There is still much research ongoing to find ways to categorize subgroups and which treatments respond well.

Asthma is not classed as a chronic obstructive pulmonary diseases, although this particular sickness is a chronic obstructive condition. Chronic obstructive pulmonary disease comprise emphysema, chronic bronchitis and bronchiectasis for example. These diseases are irreversible. In asthma, the airway obstruction is reversible, however, if left untreated, the chronic lung inflammation during asthma can become an irreversible obstruction due to airway remodeling. Asthma likewise affects the bronchi and not the alveoli as in emphysema.

Asthma Attack

Asthma attacks are usually defined as an acute asthma exacerbation. Indications of an asthma attack includes: shortness of breath, wheezing and chest tightening, although some people present mainly along with coughing. In some cases, are motion can be impaired so greatly that no wheezing is heard. During an attack, there can be a paradoxical pulse, which means a pulse which is stronger during exhalation and weaker during inhalation. The individual might have a blue tinge to their skin and nails caused by the lack of oxygen. Some muscles in the neck like for example the scalene and sternocleidomastoid muscles may become more pronounced as the person struggles for air.

The peak flow rate or likewise referred to as PEFR is =200 L/min or =50% of the best possible flow rate in a mild exacerbation. Moderate is defined as between 80 and 200 L/min or 25 percent and 50 percent of the predicted best whereas severe is defined as = 80 L/min or =25% of the predicted best.

Exercise Induced

Asthma may likewise be induced by exercise and this diagnosis is common amongst top athletes. For instance, a survey in the Summer Olympic Games held last 1996 in Atlanta showed that 15% of athletes had asthma and 10 percent were on asthma medication. The most common sports which have a high occurrence of asthma comprise mountain biking, cycling and long-distance running. Weight-lifting and diving show a fairly lower incidence. There has been evidence suggesting insufficient vitamin D levels are related with serious asthma attacks. Usually, exercise induced asthma is treated successfully with the use of a short-acting beta2 agonist.

Occupational Asthma

A lot of people suffer from asthma as because of things they are exposed to at their place of work. This is reported as occupational respiratory disease. Most of cases of occupational asthma are not reported or recognized as such. The highest percentage of cases occurred during labourers and fabricators, followed by managerial specialists and professionals as well as people in sales, administrative support and technical jobs. Most of these cases of asthma were in the services and manufacturing industries. Certain reactive chemicals are usually connected with work-related asthma as well as items like for instance enzymes, animal proteins, flour and natural rubber latex. One study reported that 15-23% of new onset asthma cases which occurred in adults are work related.


Asthma is caused by genetic and environmental factors. These issues influence how serious the asthma is as well as how it responds to medication. There have been researches showing related illnesses such as eczema and hay fever are associated. The strongest risk factor for developing asthma is a history of atopic disease. The more allergens an individual reacts to on a skin test, the higher the possibilities of them having asthma.

Much of the allergic reactions to asthma is likewise connected with sensitivities to indoor allergens. The typical style of housing within the west, would also allow greater exposure to indoor allergens. There have been mixed findings to the prevention studies aimed at the aggressive reduction of airborne allergens inside a home with infants. Like for instance, strict dust mite restriction has reduced the possibility of allergic sensitization to dust mites and moderately reduces the chance of developing asthma until the age of 8. However, similar studies with exposure to cat and dog allergies have shown that exposure during the first year of life was found to reduce the possibility of allergic sensitization and of developing asthma later in life.

Several researches within the UK and the USA have explored the risks between the development of asthma and obesity. Lots of factors which are linked with obesity may play a role in asthma pathology. Like for instance, because of a build-up of fatty or adipose tissue, a decreased respiratory function may occur. This may be partly because adipose tissue contributes to a pro-inflammatory state and this has been connected with non-eosinophilic asthma. Adult onset asthma has also been associated with Churg-Strauss syndrome and periocular xanthogranulomas.
