Allergy Testing Kitchener

Allergy Testing Kitchener - The word asthma is derived from the Greek language and means "panting." It is a chronic inflammatory illness of the airways. Asthma is characterized by variable and recurring symptoms, including reversible airflow obstruction and bronchospasm. Indications of asthma include: chest tightness, wheezing, shortness of breath and coughing. Asthma is clinically classified depending upon the frequency of symptoms, peak expiratory flow rate and forced expiratory volume in one second. Asthma could be further categorized as atopic or extrinsic or non-atopic or intrinsic.

The condition of asthma is caused by several genetic and environmental factors or combination there of. Acute indications are usually treated by making use of an inhaled short-acting beta-2 agonist like for instance salbutamol. Those who have asthma try to avoid triggers including allergens and irritants. Those who have asthma often find relief by inhaling corticosteroids. Treatments utilizing Leukotriene antagonists are less helpful than corticosteroids are usually less preferred.

Usually, a diagnosis is made based upon the pattern of indications in addition to the response to therapy over time. Since the 1970s, there has been a significant increase in asthma. According to the 2010 statistics, throughout the globe, more than three hundred million individuals are affected worldwide and 250,000 asthma fatalities were recorded in the year 2009. The prognosis for asthma is usually good because of the ability to correctly control this condition through therapy.


The classification of asthma is based upon its severity in patients, the frequency of symptoms, if the signs take place at night, FEV1 variability and predicted percent of FEV1, how intermittent and often the attacks happen. The asthma could be considered mild persistent if the attacks occur less than 2 times per week and not on a daily basis. For example, if they occur 3 to 4 times a month. Another category will be moderate persistent. These attacks could occur once a week but not each and every night. Daily attacks are considered to be severe persistent occurring usually 7 times in a week, perhaps several times per day.

Presently, there is no concise method for classifying different subgroups of asthma, even if the condition is classified based on seriousness 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, though this disease is a chronic obstructive condition. Chronic obstructive pulmonary disease comprise chronic bronchitis, bronchiectasis and emphysema for example. These diseases are irreversible. In asthma, the airway obstruction is reversible, however, if left untreated, the chronic lung inflammation during asthma could 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 defined as an acute asthma exacerbation. The classic signs consist of: wheezing, chest tightness and shortness of breath, although some individuals present mainly together with coughing. In several cases, are motion may be impaired so greatly that no wheezing is heard. During an attack, there could be a paradoxical pulse, that means a pulse which is weaker during inhalation and stronger during exhalation. The individual might have a blue tinge to their nails and skin resulting from lack of oxygen. Some muscles within the neck such as the sternocleidomastoid and scalene muscles might become more pronounced as the individual struggles for air.

In a mild exacerbation the peak expiratory flow rate or likewise known as PEFR is =200 L/min or =50% of the predicted best. Moderate is defined as between 80 and 200 L/min or 25 percent and 50 percent of the predicted best whilst severe is defined as = 80 L/min or =25% of the predicted best.

Exercise Induced

Among top athletes, asthma may be exercise induced. In the Summer Olympic Games held Last 1996 in Atlanta, a survey of the athletes showed that 15 percent of athletes had asthma and 10 percent were on asthma medication. The most common sports that have a high incidence of asthma consist of long-distance running, mountain biking and cycling. Weight-lifting and diving show a fairly lower occurrence. There has been proof suggesting insufficient vitamin D levels are associated with severe asthma attacks. Usually, asthma induced by exercise is treated successfully with the use of a short-acting beta2 agonist.

Occupational Asthma

Individuals exposed to certain workplace factors, could have asthma. These reported asthma attacks are referred to as occupational respiratory disease. Nearly all cases however, are not recognized or reported as occupational asthma. The highest percentage of cases happened during labourers and fabricators, followed by professional and managerial specialists as well as people in sales, administrative support and technical jobs. Nearly all of these cases of asthma were in the services and manufacturing businesses. Certain reactive chemicals are commonly connected with work-related asthma as well as things including enzymes, animal proteins, flour and natural rubber latex. One study reported that 15-23% of new onset asthma cases that occurred in adults are work related.


There are numerous genetic and environmental elements which trigger asthma. Many of these issues will influence how severe it responds to medication. There have been studies showing connected illnesses like eczema and hay fever are related. The strongest risk factor for developing asthma is a history of atopic disease. The more allergens a person reacts to on a skin test, the higher the odds of them having asthma.

Much of the allergic reactions to asthma is likewise connected with sensitivities to indoor allergens. The normal style of housing within the west, will likewise 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 babies. Like for instance, strict dust mite restriction has reduced the risk of allergic sensitization to dust mites and moderately lessens the risk of developing asthma until the age of 8. However, similar studies with exposure to dog and cat allergies have shown that exposure during the first year of life was found to reduce the risk of allergic sensitization and of developing asthma later in life.

Some researches within the USA and the UK have explored the risks between obesity and the development of asthma. Many factors that are related with obesity may play a role in asthma pathology. Like for example, due to a build-up of adipose or fatty tissue, a decreased respiratory function can occur. This can 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 linked with Churg-Strauss syndrome and periocular xanthogranulomas.
