What should you know about excessive wheezing?

Wheezing is a musical or whistling sound caused by air moving through narrowed airways. Asthma may cause episodes with chest tightness, cough or breathlessness. COPD can produce persistent airflow limitation, while acute bronchitis may bring wheeze during a respiratory infection. In young children, bronchiolitis can make breathing noisy and fast.

Allergy-related inflammation can accompany allergic rhinitis. Sudden wheezing after a food, medicine or insect sting, especially with swelling, hives, faintness or throat tightness, can signal anaphylaxis. A new sound after choking may indicate an inhaled object and needs prompt assessment.

Sit upright, loosen tight clothing and move away from smoke, dust or a suspected trigger. Use a prescribed reliever inhaler exactly as your asthma or COPD plan says; a spacer may help when one has been prescribed. Do not borrow another person’s inhaler or delay care while trying home remedies.

Note when the wheeze began, what preceded it, whether speech and walking are affected, and how treatment changes it. A clinician may listen to the chest and check oxygen and airflow. Nebuliser treatment is sometimes used in acute care when inhaled medicine needs to be delivered under supervision.

Call emergency services for severe difficulty breathing, blue or grey lips, inability to speak in full sentences, exhaustion, collapse, confusion, chest pain or rapidly worsening symptoms. Sudden wheezing with facial or tongue swelling, widespread hives or faintness is an emergency.

Get same-day medical advice when wheezing is new, follows choking, comes with fever, or keeps returning. Prompt review is also sensible when prescribed treatment is not helping as expected or normal activity is becoming difficult.

Ask whether the pattern fits asthma, infection, allergy or COPD; which triggers to avoid; how to use your inhaler; and what exact symptoms should activate your written action plan. Mention smoking or vaping exposure, recent illness, allergies and previous breathing attacks.
