What does blocked nose feel like with obstructive sleep apnoea?

You might feel that air does not pass freely through your nose when lying down, leading you to breathe through your mouth. On waking, your mouth or throat may feel dry, and you may notice congestion that changes during the night. Snoring, pauses in breathing witnessed by another person, gasping, morning headaches and daytime sleepiness can occur with obstructive sleep apnoea. Nasal blockage can add resistance to airflow, but it is not the only feature involved: the throat can narrow or close during sleep. A blocked nose has many possible causes, so it does not establish a diagnosis by itself.

Keep a record of when blockage occurs, whether it is worse lying down, and any snoring or breathing pauses your sleep partner notices. Treat irritants such as smoke and review persistent nasal symptoms with a clinician. Do not use decongestant nasal sprays for longer than the label advises, because overuse can worsen congestion. If sleep apnoea is suspected, arrange an assessment; testing may monitor breathing and oxygen patterns while you sleep. If treatment such as a breathing device is recommended, mention nasal blockage so the fit and comfort can be addressed.

Book an appointment for loud regular snoring, witnessed pauses, repeated choking awakenings, unrefreshing sleep, or daytime sleepiness that affects driving or work. Seek urgent help for severe breathlessness while awake, chest pain, fainting, or blue-grey lips. Prompt assessment matters if sleepiness makes it unsafe to drive or operate equipment.

Could my nasal blockage be contributing to disturbed sleep? Do my snoring and morning symptoms warrant a sleep assessment? What can I use for my nose, and how would it fit with any recommended sleep-apnoea treatment?
