Snoring is usually caused by mechanical blockage of the upper airway or systemic factors that cause narrowing of the pharyngeal cavity and vibration of the soft palate by the respiratory airflow during sleep. Depending on the cause, surgical/instrumental corrective treatment, medication, and general treatment may be used. 1. Upper airway factors: enlarged turbinates/tonsils, deviated nasal septum, hypertrophy of soft palate/adenoids and epiglottis can lead to narrowing of the upper airway/tissue collapse and increase in airway resistance leading to snoring. Detailed assessment should be made according to the different factors of upper airway obstruction, and then according to the different anatomical features, nasopharyngeal surgery/correction, continuous positive airway pressure ventilation (CPAP) treatment to enlarge the cross-sectional area of the upper airway during breathing can help to improve the symptoms of snoring. 2. Systemic factors: overweight, endocrine dysfunction, hypothyroidism, pituitary tumor, etc. can present with snoring symptoms. Relevant laboratory and imaging tests are needed to make a clear diagnosis, and the symptoms can be improved by surgery (tumor removal, etc.) or medication (endocrine disease-related drugs/thyroxine tablets, etc.). General treatments such as weight reduction and change in sleeping position can also be used to improve poor physical condition/sleep quality and to improve snoring. If snoring occurs during sleep, it is recommended to consult a doctor for systematic examination and diagnosis, and follow the doctor’s instructions to standardize the medication and treatment.
