Understanding Asthma: Causes, Symptoms, Diagnosis, and Prevention

Asthma is a long-term respiratory condition that narrows and inflames the airways in the lungs when exposed to allergens or irritants. This response leads to excess mucus production, causing symptoms like coughing, chest tightness, shortness of breath, and wheezing. The severity varies among individuals, with classifications ranging from mild intermittent to severe persistent. The exact cause of asthma remains uncertain, but genetic and environmental factors are believed to contribute. Triggers differ but often include pollen, dust, exercise, cold air, pollutants, certain medications, stress, food preservatives, and acid reflux.

Causes
Researchers suspect both hereditary and environmental factors play a role in developing asthma. Common triggers include allergens like pollen, dust, pet dander, physical activity, cold temperatures, respiratory infections, pollutants, certain drugs such as aspirin and beta blockers, stress, food additives, and acid reflux.

Diagnosis
Doctors perform physical exams and review symptoms to exclude other respiratory issues. Additional tests like spirometry and peak flow measurements assess lung function. Further assessments such as methacholine challenge tests, imaging, allergy testing, sputum analysis, and nitric oxide measurements help confirm asthma diagnosis.

Operating in tandem with diagnosis, treatment options depend on severity. Common medications include inhaled corticosteroids, combination inhalers, leukotriene modifiers, and quick-relief bronchodilators. For severe cases, procedures like bronchial thermoplasty are considered. Lifestyle adjustments—such as regular exercise, weight management, and controlling acid reflux—can help prevent asthma attacks. Maintaining a clean environment, using air conditioning, installing humidifiers, grooming pets, and protecting against cold air may reduce trigger exposure.
