Dizziness due to lack of exercise, high blood pressure and rhinitis may be caused by lack of exercise, which can be relieved by proper rest and medication. 1. Lack of exercise: patients who lack exercise are prone to cerebral hypoxia after a lot of exercise, causing dizziness. You can take proper rest after exercise and replenish water to relieve the symptoms; at the same time, you can walk around slowly to promote the return of blood flow. 2. Hypertension: Patients with high blood pressure may experience a rise in blood pressure and dizziness after exercise. Patients need to stop exercising and can take antihypertensive drugs such as hydrochlorothiazide and captopril under the guidance of a doctor for treatment. 3. Rhinitis: patients with rhinitis are prone to cerebral hypoxia and dizziness due to poor ventilation in the nose during exercise. Patients can be treated with intranasal decongestants, such as hydroxymetazoline hydrochloride spray, under the guidance of a doctor. When the symptoms of exercise hypoxia and dizziness are not relieved for a long time, it is recommended to consult a doctor in time, diagnosed by a professional doctor and given reasonable treatment.
