Dizziness caused by rhinitis is mainly because patients with rhinitis have bilateral inferior turbinate hypertrophy, swelling of the nasal mucosa and blockage of large amounts of secretions in the nasal cavity, resulting in poor ventilation of the patient’s nasal cavity, which induces generalized hypoxia, including brain hypoxia. In general, when patients experience dizziness, there is no slurred speech, no impairment of consciousness, no impairment of the movement of the limbs, but simply the manifestation of dizziness. Generally speaking, for dizziness caused by chronic rhinitis, nasal spray hormone combined with antihistamine nasal spray can be applied clinically to improve the ventilation of the nasal mucosa, reduce the swelling of the mucosa and relieve the ventilation. This can relieve the patient’s dizziness and discomfort caused by lack of oxygen.
