Sleep apnoea: signs, testing and treatment

Loud snoring, pauses in breathing, gasping and marked daytime sleepiness can indicate obstructive sleep apnoea.

Sleep apnoea fragments sleep and changes oxygen levels. It is not fixed by general sleep hygiene and is associated with cardiovascular and driving risk.

Testing matters

Diagnosis uses clinical assessment and a sleep study. Consumer wearables cannot rule it in or out reliably.
