Asthma

Asthma is chronic inflammatory airway disease with variable/reversible bronchospasm, presenting with paroxysmal wheeze, dyspnea, cough, and chest tightness, often at night/exertion/allergen exposure. Treatment: controller (inhaled corticosteroids; LABA/leukotriene antagonists/theophylline); reliever (SABA); allergen/irritant avoidance; treat comorbidities (rhinitis/GERD); treat exacerbations (SABA, systemic steroids, oxygen, magnesium); biologics (omalizumab/mepolizumab) in severe eosinophilic/allergic; patient education; monitor peak flow; vaccines.

Common Symptoms

Paroxysmal wheeze; dyspnea; cough; chest tightness; nocturnal/exertional

Causes and Pathogenesis

Allergic/nonallergic airway inflammation causes bronchial hyperreactivity and reversible obstruction.

Treatment

Inhaled steroids/bronchodilators; allergen avoidance; treat exacerbations; biologics in severe

Preventive Measures

Allergen avoidance; flu vaccine; smoking cessation; exercise as tolerated.
