The first thing to do is to determine the cause of recurrent coughing in children. Common diseases that trigger coughing include infectious and non-infectious diseases, such as pneumonia, allergic cough, and even asthma. The first and most common thing to consider is infectious diseases, such as bronchitis and pneumonia, which may cause recurrent coughing if they have not been treated properly and rationally, and some children even have bronchodilatation left behind. There are also children because the environment is not good, children around often have a cold, parents do not pay attention to life management often have a cold, do not pay attention to ventilation. Give the child to wear too much, too little, and so on, may lead to the child resistance is relatively low, often respiratory infections, cough delayed. Secondly, it is also important to pay special attention to allergy factors, the child’s allergy-induced cough, or even asthma, will be manifested in recurrent or prolonged coughing episodes. It is necessary to go to the hospital, the doctor will find a wheezing sound or rumbling when listening to the doctor, blood routine will have eosinophils increased, etc., but also can check the allergens, do pulmonary function tests, etc., a clear diagnosis. In addition, some children mistakenly inhale something in the bronchial tubes or branches, which can also cause mild and severe cough. For coughs caused by common cold, drinking more water and resting well is a good way to cure, for allergy-related coughs it is necessary to detach from allergens and anti-allergy treatment, in short, to clarify the cause of the disease in order to better treatment.
