Bronchial Asthma
Definition:
Asthma is a chronic inflammatory disease of the airways characterized by recurring episodes of wheezing, breathlessness, chest tightness, and coughing, particularly at night or early in the morning.
Causes / Etiology:
Asthma is caused by a combination of genetic and environmental factors. The exact cause is unknown but it is believed to result from an overactive response of the immune system to an allergen or irritant.
Types or Classification:
- Allergic Asthma: This type of asthma is caused by an allergic reaction to substances like dust mites, pollen, or pet dander.
- Non-Allergic Asthma: This type of asthma is caused by irritants like smoke, pollution, or respiratory infections.
- Occupational Asthma: This type of asthma is caused by exposure to certain substances in the workplace.
- Exercise-Induced Asthma: This type of asthma is triggered by physical activity.
Pathology:
The pathology of asthma involves a complex interplay of inflammatory cells and mediators in the airways. The process begins with the activation of eosinophils and mast cells by an allergen or irritant, leading to the release of histamine and other chemical mediators. These mediators cause the airway smooth muscles to contract, leading to bronchospasm and airway narrowing.
