Asthma is categorized into acute exacerbations and chronic persistent asthma. During acute exacerbation, mild asthma usually does not cause dizziness, while moderate to severe asthma may cause dizziness; while chronic persistent asthma usually does not cause dizziness, but if accompanied by a decline in pulmonary ventilation, dizziness may occur.
1. Acute exacerbation: During an acute exacerbation of asthma, the airway is in persistent spasm, resulting in ventilation obstruction, with shortness of breath, wheezing, chest tightness and dyspnea as the main manifestations.
Acute attack of asthma, if the symptoms are severe, continuous attacks, prolonged ventilation dysfunction will cause hypoxemia. When the brain is in a state of hypoxia, dizziness, nausea, profuse sweating and other manifestations often occur.
2. Chronic persistent phase: asthma patients in the chronic persistent phase, although there is no acute asthma attack, but may be accompanied by different frequency and different degrees of wheezing, coughing, chest tightness and other symptoms.
Patients with better asthma control are usually not dizzy. If the level of long-term asthma control is poor, there will be a decrease in pulmonary ventilation, which will cause dizziness due to lack of oxygen.
When asthma with dizziness occurs, one should remain vigilant and seek medical attention. Removal of allergens is the first step. Short-acting anticholinergic drugs, such as ipratropium bromide, can be nebulized and inhaled during acute exacerbations;
Inhaled glucocorticosteroids, such as beclomethasone, may be used during chronic persistent episodes. If necessary, hormones should be administered intravenously or mechanical ventilation should be given to ensure oxygen supply to vital organs.
