The main symptoms of OSAS are snoring, intermittent hypoxia, chest tightness, shortness of breath, sleep disorders and other adverse symptoms during sleep, which may lead to death by asphyxiation in severe cases. The causes of obstructive sleep apnea syndrome mainly include congenital jaw deformity, tonsillar hypertrophy, pharyngeal occupational lesion, excessive mental stress, etc. If the disease is caused by mental stress factors, the mental state can be adjusted first and then observed. If the symptoms persist, it is recommended that you can go to a regular hospital to receive further examination to identify the specific cause and then carry out symptomatic treatment.
