There is no clinical information to prove that there are tips for treating cough. Clinical causes of cough may be lung infection, asthma, gastroesophageal reflux disease, etc., and generally need to be treated according to the cause. 1. Lung infections: Commonly caused by bacterial or mycoplasma pneumonia, there may be coughing, coughing up sputum and other symptoms, with or without chest pain. If it is caused by bacterial infection, cephalosporin antibiotics such as cefixime can be used; if it is caused by mycoplasma pneumonia infection, macrolide antibiotics such as azithromycin can be used. 2. Asthma: it is a heterogeneous disease characterized by chronic inflammation of the airways with the participation of multiple cells and cellular components, and may have symptoms such as cough, wheezing and chest tightness. Inhaled glucocorticoids are preferred for long-term control, such as budesonide powder inhaler. If accompanied by wheezing, β2 agonists can be preferred to relieve symptoms, such as terbutaline. 3. Gastroesophageal reflux disease (GERD): It is often caused by dysfunction of the lower esophageal sphincter, which leads to reflux of gastric contents into the pharynx or airway, causing cough. Proton pump inhibitors such as omeprazole, gastric power drugs such as mosapride and other drugs can be used to relieve cough symptoms. There are many other causes of cough, such as heart failure and postnasal drip syndrome. If you have a recurrent cough or symptoms worsen, you need to see a doctor as soon as possible, improve the examination, clarify the cause of the disease, and follow the doctor’s instructions for treatment, so as not to delay the condition.
