Sleeping snoring in children may be related to acute respiratory infections, or it may be caused by allergic rhinitis or adenoid hypertrophy. 1. Acute respiratory tract infection: if the child usually sleeps without snoring, but in the near future, the phenomenon of sleep snoring suddenly appeared, more considerations may be related to respiratory tract infection, mainly due to nasal congestion, resulting in the nose ventilation is not smooth and caused by snoring. 2. Allergic rhinitis: due to the increase of nasal secretion, resulting in severe nasal congestion, causing the child to sleep with his mouth open to breathe, easy to snore. 3. Adenoid hypertrophy: If the child’s adenoids are enlarged, resulting in a narrow airway, leading to poor breathing during sleep, it will show the phenomenon of snoring. If your child snores a lot, we recommend that you seek medical attention as soon as possible to diagnose the cause and then be guided by your doctor.
