What are the reasons why children's coughs cannot be cured for a long time?

Children's cough that lasts for a long time usually occurs in spring and autumn. There are three main factors that cause children's cough to last for a long time. The first is the changeable temperature and the large temperature difference between day and night. Just when the cough is slightly better, it catches a cold again. The second is the air quality. Coughing is most common on foggy days. The third is the long-term cough caused by asthma, which requires long-term standardized treatment to recover.

When spring and summer come together, the temperature changes suddenly. When you are in a good mood, you can feel the warmth of early summer, and when you are in a bad mood, you can feel the cold of early spring. It is this season that makes parents confused. They are prone to catching colds when they wear too much or too little. They always cough repeatedly. Other symptoms are not obvious, but they always cough. Why does a child's cough not heal after a long time of treatment?

1. Temperature changes and repeated respiratory infections

If a child has a persistent cough, many doctors will diagnose it as an upper respiratory tract infection and prescribe some cold medicines. However, just when the child has improved, the cough will suddenly get worse due to a sudden change in nature. This will happen repeatedly, resulting in a persistent cough.

2. Bad air quality causes repeated coughing

The quality of air has a significant relationship with children's cough. Because children's respiratory tract is not fully developed, when it is foggy, some bacteria particles in the fog can easily infect the lungs or irritate the lungs, causing repeated coughing. In this case, outdoor activities should be reduced as much as possible.

3. Cough caused by asthma

The only or main symptom of some asthma patients is persistent coughing, which recurs repeatedly and is difficult to cure, without obvious wheezing. This condition is called cough variant asthma. Some are allergic coughs, which are a special form of asthma.

Like typical asthma, cough variant asthma is often triggered or aggravated by exercise, cold air, climate change or upper respiratory tract infection. Some patients may also suffer from viral or mycoplasma infection.

The symptom of cough variant asthma is long-term cough, which may recur throughout the year or may be seasonal. The cough is more severe in the early morning and evening, mainly dry cough, and lasts for several weeks to several years. Examination shows no obvious lung wheezing, normal lung function test or increased airway resistance, and no other obvious abnormalities. It is easy to be misdiagnosed as recurrent upper respiratory tract infection, bronchitis, etc.
