London GP Warns Loud Snoring, Daytime Sleepiness May Signal Heart-Straining Sleep Apnoea

Health bodies link sleep apnoea to higher cardiovascular risk, with treatment advised for symptoms rather than proven heart protection.

Overview

  • Dr Leen Tannous urged people who snore loudly or feel excessively sleepy during the day to seek assessment for possible obstructive sleep apnoea.
  • Her Instagram post highlighted common mistakes that worsen snoring, including drinking alcohol before bed, using sedatives, ignoring persistent symptoms, and skipping lifestyle changes.
  • She warned that driving while excessively sleepy is dangerous, noting untreated sleep apnoea is linked to a higher risk of road accidents.
  • NHS guidance describes sleep apnoea as repeated pauses in breathing during sleep and lists symptoms such as gasping, waking frequently, loud snoring, morning headaches, and trouble concentrating.
  • The American Heart Association cites links between sleep apnoea and hypertension, stroke, and coronary disease, while the British Heart Foundation notes treatment can lower blood pressure but has not been shown to reduce major cardiovascular events.
