Sleep apnoea is when your breathing stops and starts while you sleep. The most common type is called obstructive sleep apnoea.
The main symptoms of sleep apnoea include making gasping or choking noises while you sleep, loud snoring and feeling very tired during the day.
Sleep apnoea is usually treated with a mask you wear while you're asleep (CPAP machine).
Sleep apnoea is caused by your airways becoming relaxed and narrow while you sleep. It's linked to things like obesity and getting older.
