Loud snoring is caused by the vibration of the soft palate due to the normal airflow inhalation and exhalation impacting the soft palate when the airway is narrowed, resulting in the phenomenon of snoring. It may be related to tonsil hypertrophy, chronic hypertrophic rhinitis, deviated nasal septum and other diseases. 1. Tonsillar hypertrophy: Tonsillar hypertrophy can block part of the airway, forcing open-mouth breathing to increase the oropharyngeal cross-section, directing the airflow to the soft palate, thus leading to the occurrence of night snoring. 2. Chronic hypertrophy: this disease can lead to nasal congestion, which makes the airflow in and out not smooth, and in serious cases, it is necessary to use the mouth to breathe, which leads to snoring symptoms. 3. Deviated nasal septum: severe deviation can lead to bilateral nasal congestion, which not only leads to loud snoring, but also accompanied by headache, nosebleed and compensatory hypertrophy of nasal mucosa. It is recommended to go to the hospital ear, nose and throat consultation, clarify the cause of the disease, and carry out targeted treatment.
