Wheezing for months: what to know

Ongoing wheeze can reflect asthma, chronic airway irritation, allergic rhinitis with post-nasal drainage, or another lung problem. COPD can cause persistent airflow limitation, particularly in people with a history of smoking. Acute bronchitis may leave cough and noisy breathing for a while, but continuing symptoms still deserve review. Bronchiolitis is more relevant to infants and young children.

Notice whether the sound is present at rest, after activity, at night, or around dust, pets, mould, cold air, or smoke. Tell the clinician about cough, phlegm, chest tightness, fever, breathlessness, reflux, medicines, and past lung conditions. These details help distinguish airway narrowing from sounds arising higher in the throat.

Book an appointment rather than treating months of wheeze as a temporary irritation. A clinician may examine your chest, review medicines and exposures, and arrange breathing tests or other checks when appropriate. Avoid cigarette smoke, vaping aerosols, and known irritants. Keep a simple symptom diary and bring every inhaler or medicine you use.

Use prescribed inhalers according to their instructions. Do not start antibiotics, steroids, or someone else’s inhaler without medical advice; the right treatment depends on the cause.

Get emergency help for severe breathing difficulty, blue or grey lips, faintness, confusion, inability to speak comfortably, chest pain, or sudden swelling of the lips, tongue, or throat. Seek same-day medical advice when breathlessness is worsening, you cough blood, develop a high fever with breathing trouble, or your reliever inhaler is not giving the expected relief.

Ask what causes are being considered, whether you need lung-function testing, how to use each inhaler, which exposures to avoid, and what change should prompt urgent help.
