There are many causes of nasal disinflation: colds, hyperplasia, nasal malformations, allergic diseases of the nose, and nasal foreign bodies.
1, cold: because when the organism has a cold, it may be accompanied by fever, sneezing, runny nose and other symptoms. At the same time, the nasal mucosa is acutely congested and swollen thus causing the nose to be unventilated.
2.Proliferative hypertrophy: If the proliferative hypertrophy will block the posterior nostrils, the symptoms of poor ventilation and obstructed breathing will appear when sleeping, which is common in children and very rare in adults, mainly manifested as open-mouth breathing and snoring in sleep.
3.Nasal malformation: If it is a congenital nasal malformation, it may be an occlusion of the anterior nostril or posterior nostril, in this case, it is easy to appear the phenomenon of nose non-ventilation.
4.Nose allergic diseases: usually this disease is caused by dust allergy, cold and wind stimulation, etc., the body will appear the phenomenon of edema of the respiratory mucosa, so that the nasal cavity is blocked.
5, nasal foreign body: If there is a foreign body in the nasal cavity, such as peanut rice, beans, melon seeds, etc. in the nasal cavity for a long time will occur swelling, thus increasing the degree of nasal blockage.
Usually the phenomenon of nasal non-ventilation is caused by the above-mentioned reasons.
