Why does my child always cough and have phlegm?

If a child is always coughing, it may be because he has some diseases that can cause coughing, such as acute bronchitis, which can cause coughing, and if there is a lot of sputum, it is often caused by bacterial infection. In addition, I think it is more caused by upper respiratory tract infection. Children's colds belong to this phenomenon. In addition, children under two years old may suffer from bronchopneumonia, which eventually leads to coughing.

As the saying goes, nine out of ten babies cough! Because the baby's respiratory tract is still fragile and not fully developed, the baby will often develop respiratory diseases at the slightest disturbance. From a medical point of view, a baby's cough is a defensive reflex of the body to expel respiratory secretions or foreign objects. In other words, coughing is a protective physiological phenomenon for babies. But if the coughing is too severe and affects diet, sleep and rest, then it loses its meaning of protecting the baby.

Age of coughing If a newborn baby has a cough, you should be careful about diseases such as aspiration pneumonia and congenital lung developmental abnormalities. Cough in older children is generally more common in respiratory tract infections. If a preschool baby coughs, airway infection and foreign bodies in the airway should be taken into consideration. Coughing time: If your baby coughs in the morning, it is most likely a chronic disease, such as chronic inflammation of the upper respiratory tract and chronic bronchitis. If your baby coughs at night, it may be caused by diseases such as whooping cough and acute spasmodic laryngitis.

In addition to the causes of cough introduced above, some children may have cough due to acute laryngitis. At this time, the voice will quickly become hoarse, or even unable to make a sound, and rapid wheezing sounds will be made when breathing. Depending on the severity of the cough, it can be divided into acute, subacute or chronic cough. Generally speaking, chronic cough is often caused by allergic bronchitis or gastroesophageal reflux.
