What happens if obstructive sleep apnoea is not treated?

During sleep, the throat can narrow or close repeatedly. Each interruption may briefly arouse the brain, even when you do not remember waking. Sleep therefore becomes unrefreshing, which can cause fatigue, morning headache, difficulty concentrating, irritability and memory problems. Snoring is common, but it does not confirm the diagnosis; breathing pauses, gasping or witnessed pauses are more useful clues.

Over time, untreated breathing interruptions can place strain on the heart and blood vessels and may make blood pressure harder to control. Daytime sleepiness can also impair driving, work and other tasks requiring sustained attention.

Arrange a GP assessment if you snore loudly, wake gasping, or feel unrefreshed despite enough time in bed. Your clinician may ask about sleep timing, medicines, alcohol, weight, nasal blockage and what a bed partner has observed. Sleep testing can record breathing and oxygen patterns at home or in a clinic. Treatment depends on the findings and may include a breathing device, positional measures or other tailored support.

Until assessed, take daytime sleepiness seriously: avoid driving or operating machinery when you may nod off, and tell someone if breathing pauses are being observed.

Seek urgent help for severe breathlessness while awake, fainting, new chest pain, blue lips, or confusion. Contact a clinician promptly if sleepiness is causing near-misses while driving or if symptoms are worsening. These situations need assessment for immediate safety and other possible causes.

Could my snoring and daytime fatigue indicate sleep apnoea? Do I need a sleep study? Which treatment suits my breathing pattern and routine? How can I reduce driving risk while waiting for assessment?
