Asthma is marked by inflammation of the bronchial tubes, with extra sticky secretions inside the tubes. (webmd.com)
Asthma symptoms can appear when someone is exposed to possible triggers, meaning something they're sensitive to that causes airway inflammation. (hsi.com)
These factors are divided into those that cause inflammation (the most important), respiratory irritants and other factors. (asthme-quebec.ca)
Inflammatory factors cause airway inflammation (swollen) and can prolong asthma symptoms for weeks or months, depending on the length of exposure. (asthme-quebec.ca)
Substances in the workplace can also cause bronchial inflammation or asthma. (asthme-quebec.ca)
Tobacco smoke is a major respiratory irritant that aggravates airway inflammation. (asthme-quebec.ca)
The presence of certain key symptoms may suggest the presence of asthma, but can also result from airway inflammation alone, from chronic rather than reversible airflow limitation, or from other respiratory and nonrespiratory conditions. (cmaj.ca)
The inflammation associated with asthma is characteristically eosinophilic. (cmaj.ca)
However, some patients with this condition have neutrophilic inflammation, whereas, conversely, some patients without asthma have eosinophilic inflammation. (cmaj.ca)

Asthma triggers are factors or stimuli that provoke the exacerbation of asthma symptoms or increase the degree of airflow disruption, which can lead to an asthma attack. (wikipedia.org)
Acute asthma exacerbation in children. (epnet.com)
Multiple respiratory hazards have been identified in the The employee, a woman aged 27 years, began work at an cannabis cultivation and production industry, in which indoor cannabis cultivation and processing facility on May 20, occupational asthma and work-related exacerbation of 2021. (cdc.gov)
The study was developed because the prevalence of asthma symptoms are high among adolescents and over the years other risk factors have been associated with its exacerbation. (bvsalud.org)

A stepwise approach is taken for the long-term management of asthma after confirming the diagnosis and assessing the severity of disease [NHLBI 2007, GINA 2011]. (cdc.gov)
If these tests are positive and the symptoms match, a diagnosis of asthma is very likely. (aha.ch)
Asthma can be controlled with the proper diagnosis and treatment. (healthywomen.org)
Sara states that she has never received a diagnosis of asthma. (cmaj.ca)
The first step in managing asthma is to make the correct diagnosis. (cmaj.ca)
8 However, despite the significant expenditure of health care resources on people with asthma, as well as decades of improvements in diagnosis and treatment and regular updates of evidence-based clinical practice guidelines, asthma control at the population level remains suboptimal. (cmaj.ca)
Canadian guidelines for the diagnosis and treatment of asthma have existed since 1989 and were most recently updated in 2003. (cmaj.ca)
In this series, we are using case-based examples to highlight recent changes in recommendations for asthma management and to highlight practical aspects of diagnosis and treatment. (cmaj.ca)
Although many clinicians diagnose asthma on the basis of a trial of therapy, objective measurements are necessary to confirm the clinical diagnosis. (cmaj.ca)
Thus, a conclusive diagnosis of asthma is based on tests designed to detect rapid changes in the forced expiratory volume in 1 second (FEV 1 ) or peak expiratory flow. (cmaj.ca)
Although this review focuses particularly on diagnosis, these tests can also be used to assess asthma control and as an aid in optimizing chronic therapy. (cmaj.ca)
Identification of airway hyperresponsiveness thus has clinical value, particularly in the diagnosis of asthma in people with normal spirometry results or with symptoms uncharacteristic of asthma. (cmaj.ca)
Measurement of sputum eosinophilia has been proposed for clinical use in the diagnosis of asthma. (cmaj.ca)
The first step in managing your asthma is getting an accurate diagnosis. (acaai.org)

An asthma attack is usually mediated by an inflammatory pathway, where a trigger such as an allergen could lead to a series of immune response mediated by various types of immune cells. (wikipedia.org)
The pathophysiology for asthma mainly involves the inflammatory pathway, associated with several types of immune cells in the body, mainly T helper 2 cells (Th2 cells), B cells and mast cells. (wikipedia.org)
In a nut shell, as a stimulus, such as an allergen comes into contact with an asthma patient, it activates various types of immune cells leading to an inflammatory response, causing bronchial hyperresponsiveness, bronchoconstriction, excessive mucus secretion, airflow obstruction and an asthma attack. (wikipedia.org)
This has allowed us to study aspects of the disease that are underlying the inflammatory airway disease that is central to asthma. (medscape.com)
