What should you know about bilateral expiratory wheezing?

Wheezing happens when air moves through narrowed or inflamed airways. Asthma can cause variable wheezing, chest tightness, cough, and breathlessness, often after triggers or exercise. COPD may produce persistent symptoms, particularly in people with a smoking or occupational exposure history. Acute bronchitis can temporarily irritate the airways. Allergic rhinitis may add nasal symptoms, while bronchiolitis is mainly a concern in young children. The sound alone cannot establish the cause; breathing rate, oxygen level, age, medical history, and examination matter.

Stop exertion, sit upright, and move away from smoke, dust, or a known trigger. If you have a prescribed reliever inhaler, use it exactly according to your personal plan. Arrange medical review for new, recurrent, or unexplained wheezing, especially when cough or breathlessness limits activity. A clinician may listen to your chest and assess oxygen levels; a nebuliser treatment may be considered when inhaled medicine needs to be delivered during a more difficult episode.

Call emergency services for severe breathlessness, inability to speak in full sentences, blue or grey lips, drowsiness, collapse, or rapidly worsening wheezing. Treat wheezing with facial swelling, hives, vomiting, or sudden throat tightness as possible anaphylaxis and seek emergency help immediately. Children with poor feeding, unusual sleepiness, or struggling breaths also need urgent assessment.
