Rhinitis can cause dizziness because the mucosa of the nasal cavity is swollen and congested in patients with rhinitis, and the sinus openings of the sinuses are also swollen and congested. The swollen turbinates can resist the nasal septum, which can cause reflex dizziness and even headaches. Rhinitis can cause narrow blockage of the sinus orifices and negative pressure in the sinus cavity, which can cause dizziness. For dizziness caused by rhinitis, the main treatment is to use nasal astringent medications and anti-allergy medications to restore the swollen nasal mucosa and sinus openings, thus relieving the symptoms of nasal congestion and dizziness. Such patients should take care to exercise regularly to strengthen their body and avoid colds as much as possible, as repeated colds can aggravate the symptoms of rhinitis. Patients should also correct their lifestyle habits and strictly control their intake of tobacco and alcohol to avoid irritating the mucous membrane of the nose and pharynx and aggravating the symptoms of rhinitis. If symptoms of rhinitis are suspected, patients need to seek medical attention in a timely manner to avoid delaying the condition and reducing the effectiveness of treatment.
