Cough is a very common symptom and can be seen in a variety of diseases. It is also very common for children to have recurrent coughs or coughs that persist for a long time, for several possible reasons: recurrent respiratory infections, chronic coughs, and also the possibility of airway foreign bodies. Children with a low immune system are particularly prone to recurrent respiratory infections, which can lead to recurrent coughs. For coughs caused by respiratory infections, if the cough is caused by a cold, you can take medications for cold and cough, which have the effect of relieving the wind and relieving the cough; bronchitis and pneumonia are also important causes of coughs, and you may need to take cough and phlegm medicines and, if necessary, antibiotics and nebulized inhalation treatment. Usually, you can take drugs to improve your resistance. Or use Chinese massage and compresses to improve resistance. If the cough is chronic for more than 4 weeks, the treatment should be based on the specific cause. If the cough is post-infection, it usually heals spontaneously in mild cases and requires medication in severe cases; if the cough is caused by upper airway syndrome (rhinitis, sinusitis, pharyngitis, adenoid hypertrophy, etc.), the primary cause should be treated; if it is cough variant asthma, nebulization, anti-inflammatory drugs and bronchodilator drugs should be used. If the cough is recurrent for a long time and there is a history of suspected foreign body aspiration, bronchoscopy and treatment can be done. In conclusion, a child’s cough is just a symptom. It is important to analyze the cause of the child’s constant cough and prescribe the right medicine to control the condition very effectively, but of course, you also need to pay attention to dietary regimen for supplementary treatment.
