When you snore, your tongue, mouth, throat or airways in your nose are vibrating as you breathe. This is because these parts of your body have relaxed and narrowed while you’re asleep. If your snoring is caused by a more serious condition like sleep apnoea, your airways will become blocked while you sleep and you may make gasping or choking sounds. If your partner describes your snoring in this way, and you’re feeling very tired during the day, you should speak to your doctor for specialist treatment.
