AsthmaAsthma is the country's leading respiratory disease. In Canada, 2.4 million people have asthma. In Quebec, it is estimated that 700 000 people struggle with this illness, among them 300 000 children.

Each year, in Quebec, asthma is responsible for 760 000 medical visits, 100 000 emergency room visits, 56 000 hospitalisation days, 325 000 lost work days, 4 000 calls for ambulance services and 150 deaths. Asthma costs $150 million per year.

What is asthma?

It’s a chronic respiratory disease characterized by inflammation and partial reversible obstruction of the bronchial airways, and affecting a large number of children and adults. Because of their hypersensitivity, the airways react by contracting and clogging up when irritated, which makes breathing difficult.

The obstruction is caused by three mechanisms:

This bronchial obstruction can produce the following symptom(s):

A severe asthma attack can be a terrifying experience producing a feeling of suffocation, breathlessness and loss of control. Poorly treated or underestimated asthma can place a person’s life at risk.

What causes asthma?

The precise causes of asthma are not well known, but they appear to be the result of a complex interaction between several factors: genetic (family predisposition) and environmental.

Factors that triggerthe symptoms of asthma

Irritating factors

The irritants produce a contraction of the air- ways(bronchoconstriction).

The symptoms of the bronchoconstriction caused by the irritants are usually immediate, brief and reversible with the help of rescue medication (bronchodilators).


Inflammatory factors

 

Allergens

Respiratory infections

  • dust mites
  • food allergies
  • animals
  • mould spores
  • pollens
  • cigarette smoke
  • cold
  • flu
  • sinusitis

The symptoms caused by inflammatory factors often appear later. They may produce or exacerbate the symptoms of asthma for several weeks, or even months, and are not so easily reversible.

Other factors

How to prevent asthma

There is no cure for asthma, but proper medication can help control and manage ashtma. The treatment for managing the symptoms of the disease include anti-inflammatories designed to reduce and prevent bronchial inflammation, and bronchodilators that relieve occasional or immediate symptoms.

Asthma specialists agree that the best way to treat individuals is to actively involve them in the therapy. Despite the fact that drugs are very effective in treating asthma, successful treatment depends largely on proper understanding of the disease, environmental control and avoiding ashtma triggers.

Over 60% of asthmatics lack sufficient ability to manage their disease, which translates into daily symptoms, increased medication, emergency room visits with frequent hospital stays, absenteeism from work and school.

A better understanding of the disease and adequate treatment could prevent more than 80% of deaths, while reducing the number of emergency room visits by almost 50%, and the number of hospital stays by up to 80%.

For optimal quality of life…

Asthmatics should be able to lead a normal life with as few symptoms as possible. To achieve this, they must:

How can you tell if your asthma is being managed properly?

Asthma is considered to be properly managed when the following criteria are met:

The Info-Asthma program

The Info-Asthma program is based on asthma management and control. It is designed to inform asthma sufferers, and encourage them to gain a better understanding of their illness so that they can manage it more effectively. It is possible to live with practically symptom-free asthma, by adopting new attitudes.

This program offers free telephone assistance provided by asthma health professionals.

You will have access to comprehensive literature including:

An asthma guide
Brochures : Asthma
Asthma triggers
The Asthma logbook - PEF
Asthma action plan
Occupational asthma
Web site: www.pq.lung.ca from which you can download documents and view the various services available to the public.
 

If you don’t have the Info-Asthma Guide, contact our INFO-ASTHMA Helpline to obtain a copy.
