Snoring generally refers to snoring, which refers to the snoring sound caused by the vibration of the soft palate caused by the impact of the airflow through the upper respiratory tract during sleep. Snoring at night may be related to obesity, or it may be caused by some diseases, such as adenoid hypertrophy, nasal polyps, acute rhinitis, etc., which should be consulted in time to find out the cause. 1. Obesity: some obese people may have more fat in the neck, and the accumulation of fat may cause narrowing of the airway, which may lead to the symptom of snoring during night sleep. 2. Adenoid hypertrophy: it refers to pathologic hyperplasia and hypertrophy of adenoids due to pharyngeal infection or repeated inflammatory stimulation, which is common in children. The enlarged adenoids can block the posterior nostril and compress the eustachian tube to different degrees, causing nasal congestion, runny nose, stuffy ears and other symptoms, as well as snoring, sinusitis and obstructive sleep apnea hypoventilation syndrome and other complications. 3. Nasal polyps: a common chronic disease of nasal and sinus mucosa, larger polyps can appear nasal congestion, decreased sense of smell and other manifestations, severe speakers have an occlusive nasal sound, but also cause snoring at night sleep, loss of sense of smell and other manifestations. 4. Acute rhinitis: due to the inflammatory reaction of the nasal mucosa infected by bacteria and viruses, it can affect the ventilation of the airway, leading to respiratory obstruction, which will lead to the symptoms of snoring at night, usually accompanied by fever, coughing, shortness of breath, etc. If the symptoms persist, it will lead to the symptoms of snoring at night. If snoring at night persists and affects your sleep, you should consult a doctor in time and get a clear diagnosis, and then the doctor will carry out appropriate treatment.
