What Happens During an Asthma Attack

Airway Constriction: During an asthma attack, the muscles around the airways tighten, narrowing the breathing passages.
Inflammation Spike: The lining of the airways swells, further restricting airflow and making each breath harder.
Mucus Overload: Thick mucus floods the bronchial tubes, blocking oxygen flow to the lungs.
Wheezing Sound: As air struggles to move through tight airways, it creates the signature whistling wheeze.
Oxygen Drop: Reduced airflow lowers blood oxygen levels, causing dizziness, fatigue, and chest tightness.
CO₂ Buildup: Trapped carbon dioxide disrupts normal breathing rhythm and increases discomfort.
Trigger Response: Allergens, cold air, exercise, or stress can set off the body’s overactive immune reaction.
Panic Cycle: Shortness of breath can cause anxiety, which further intensifies breathing difficulty.
Emergency Signal: Severe attacks can prevent adequate airflow, requiring immediate medical attention.
Maintenance Required: Avoiding triggers, using inhalers, and managing inflammation keep airways open and breathing steady.
