Sleep apnoea happens if your airways become narrowed, stopping you breathing properly during sleep. The commonest type is called obstructive sleep apnoea (OSA), which is linked to being overweight, with a narrowing of the upper airways. Other risk factors include having a large neck, enlarged tonsils/adenoids, smoking, drinking alcohol (especially if heavily), sleeping on your back, a family history of apnoea and getting older (although children and young adults can get it).
Symptoms mainly happen during sleep, including making unusual sounds, such as choking, gasping, snorting or loud snoring. Your breathing may also stop and start, and you may wake frequently. In the day, you may notice you’re very tired or moody, and have headaches or difficulty concentrating.
It’s important to discuss your symptoms with your GP, as sleep apnoea…
