Common conditions
Evidence-based diagnosis & long-term management
Asthma
A chronic condition where airways narrow, swell and produce extra mucus, making breathing difficult.
Reversible airway narrowing — modern control is the goal, not just relief.
Read the asthma guide
COPD
A progressive lung disease, usually from smoking or biomass smoke, that narrows airways and traps air over time.
Slowing the decline — and treating exacerbations early.
Read the COPD guide
Lung infections
Infections of the lung tissue and airways — from pneumonia to bronchitis and tuberculosis.
Prompt diagnosis and the right antibiotic — not the strongest one — prevent complications.

Obstructive sleep apnoea (OSA)
Repeated collapse of the airway during sleep, cutting off breathing for seconds at a time.
Heavy snoring and daytime sleepiness aren't normal — they're treatable.
Read the sleep apnoea guide
Interstitial lung disease (ILD)
Scarring and inflammation deep in the lung tissue that stiffens breathing over time.
Progressive scarring of the lungs — early diagnosis protects the breathing you still have.
Read the ILD guide
Lung cancer
Abnormal cell growth in lung tissue, often first spotted as a shadow on a scan.
Early detection and a clear staging pathway change what comes next.
