Asthma throat clearing is useless and cannot relieve asthma symptoms. 1. Bronchial asthma is a chronic inflammatory disease of the airways mediated by mast cells, eosinophils, lymphocytes and other inflammatory cells, manifested by swelling and congestion of the bronchial mucosa, increased secretions, inflammatory cell infiltration in the airways, airway smooth muscle spasm. 2. Throat clearing can only clear the secretions in the throat and cannot relieve asthma symptoms. 3. The treatment of asthma mainly includes detachment from allergens and medication. Drug therapy mainly uses inhaled glucocorticoids such as budesonide, combined with β2-adrenergic agonists such as formoterol, theophylline extended-release tablets, anticholinergic drugs such as ipratropium bromide and other drug therapy. Asthma patients should strengthen their physical fitness, avoid allergen exposure, use medication to relieve asthma attacks immediately, and go to the hospital immediately when the symptoms are severe.
