What are the symptoms of asthma?

Asthma is a chronic respiratory condition characterized by symptoms that can vary in intensity and frequency among individuals. It is marked by episodes of airflow obstruction and airway hyperresponsiveness.

Key insights from the research papers include:

Asthma symptoms include wheezing, cough, chest tightness, and dyspnea, often associated with reversible airway narrowing and hyperresponsiveness to bronchoconstrictor stimuli .
The interaction between asthma and cigarette smoking can exacerbate symptoms, accelerate lung function decline, and impair therapeutic response to corticosteroids.
Airway inflammation is central to asthma's clinical manifestations, with increased levels of inflammatory cells like eosinophils and mast cells, even in mild cases.
Asthma is a heterogeneous condition with symptoms that can start in childhood and has a strong genetic component.
The disease is associated with increased susceptibility to infections, which can act as triggers and worsen the condition.

In conclusion, asthma presents with a range of respiratory symptoms, primarily wheezing, coughing, chest tightness, and shortness of breath, which are exacerbated by factors such as smoking and infections. The underlying airway inflammation is a key aspect of the disease, contributing to the variability and severity of symptoms experienced by patients.

Summary

Sources and full results

Asthma and cigarette smoking

Asthma and cigarette smoking interact to cause more severe symptoms, accelerated lung decline, and impaired short-term therapeutic response to corticosteroids.

The role of nerves in asthma

Asthma symptoms are linked to changes in the nervous system, affecting primary afferent (sensory) nerves, central nervous system integration, autonomic ganglia, and postganglionic neuroeffector junction.

Airway inflammation and asthma.

Airway inflammation is central to the pathogenesis of asthma, with increased numbers of activated eosinophils and mast cells, and potential structural changes contributing to airway hyperresponsiveness.

Asthma

Asthma has a strong genetic component and is associated with increased susceptibility to infection and changes in microbial communities in the airways.

The definition and diagnosis of asthma

Asthma is diagnosed by recognizing patterns of symptoms, such as wheeze, cough, chest tightness, and dyspnoea, and confirming that the patient experiences variable or reversible airflow obstruction.

Pathology of asthma

Asthma is an inflammatory disease affecting the airways, leading to airway hyperresponsiveness, obstruction, mucus hyper-production, and airway wall remodeling, with potential treatments focusing on Th2 cytokines.

Asthma is associated with increased susceptibility to infection.

Asthma is associated with increased susceptibility to infection, potentially affecting the immune system's ability to fight infections.

SYMPTOMS, CAUSES AND TREATMENT OF ASTHMA: A Review

Asthma is a chronic disease affecting the respiratory tract, with heritable factors and a changing living environment contributing to its increased rates.

The causes of asthma.

Asthma is caused by inflammation in the airways, which can lead to complications like pneumonia and respiratory failure if untreated.

Asthma

Asthma management focuses on symptom control, risk factors, comorbidities, and side-effects, with new biological therapies and biomarkers enabling phenotype-specific interventions and personalised treatment.
