Snoring alone does not diagnose sleep apnoea. Assessment matters when someone notices breathing pauses, choking sounds or persistent daytime sleepiness. NHS guidance describes overnight breathing tests, sometimes performed at home. A sleeping partner may observe events the person cannot recall, making their description useful at consultation. Treatment may include a device that keeps the airway open using positive air pressure, depending on assessment. Severe sleepiness is a safety concern, particularly for driving. Do not self-prescribe sleeping pills, which can worsen apnoea. A snoring app cannot replace diagnosis and follow-up.
