Asthma Treatment

Asthma is confirmed by demonstrating reversible airflow obstruction on spirometry — an improvement in FEV1 of 12% or more after bronchodilator administration. Clinical history of episodic wheezing, cough, chest tightness, and shortness of breath — particularly triggered by exercise, allergens, or cold air — supports the diagnosis.

Rescue inhalers (short-acting beta-agonists like albuterol) provide rapid symptom relief during acute bronchospasm — they do not treat underlying inflammation. Controller inhalers (inhaled corticosteroids, long-acting bronchodilators) are taken daily to reduce inflammation and prevent symptoms — they are not effective for acute attacks.

Asthma has no cure but can be very effectively controlled. Some children experience significant improvement or apparent resolution by adulthood, though airway hyperresponsiveness often persists. Adults with well-controlled asthma may be able to step down therapy under clinical guidance — but this requires careful monitoring.

Well-controlled asthma means symptoms occur less than twice per week, nighttime awakenings from asthma are rare, rescue inhaler use is less than twice weekly, and asthma doesn't limit activity. Using a validated questionnaire like the Asthma Control Test at each visit provides objective monitoring.

Inhaled corticosteroids (ICS) may cause oral thrush and hoarseness — rinsing the mouth after use prevents this. High-dose ICS can modestly affect bone density. Short-acting beta-agonists may cause tremor and palpitations. Biologics for severe asthma require injection site monitoring. Overall, inhaled medications have far fewer systemic effects than oral alternatives.
