Night snoring is due to upper airway factors (anatomically related causes) or systemic factors (e.g. obesity, etc.). 1. Local factors in the upper airway: enlarged tonsils or turbinates, deviated nasal septum, hypertrophy of the soft palate or adenoids, and narrowing/collapse of the upper airway caused by epiglottis lesions. These factors can increase airway resistance and lead to snoring symptoms. 2. Systemic factors: overweight or obesity, poor sleeping habits, impaired thyroid function, pituitary tumors, endocrine dysfunction and other causes may cause snoring symptoms. Snoring can be simple snoring, can also cause obstructive sleep apnea hypoventilation syndrome, it is recommended to actively seek medical attention, a clear diagnosis.
