What causes asthma and bronchitis in children?

In the pediatric outpatient clinic, some children will experience wheezing and difficulty breathing when they catch a cold or cough. Usually this means that the child has asthma or bronchitis. Many parents are worried about this, so they are eager to learn about the treatment methods. The following is a brief introduction to the treatment of asthma and bronchitis in children. I believe that after reading it, you will know how to treat it.

1. Respiratory tract infection

Asthma has an important relationship with respiratory tract infections. Upper respiratory tract infections are relatively common triggering factors. Most asthma patients experience worsening wheezing after respiratory tract infections, and this is more obvious in children. Surveys show that viral respiratory infections are the main cause of asthma exacerbations. Viral respiratory infections have the potential to enhance airway anti-inflammatory effects, and this factor is very similar to the pathogenesis of asthma.

2. Nonspecific factors

Dust, gasoline, smoke, paint and other irritating odors and cold air can stimulate the sensory nerve endings of the bronchial mucosa, reflexively causing vagus nerve excitement and coughing, leading to bronchial smooth muscle spasm on the basis of airway hyperresponsiveness.

3. Mental reasons

Drastic changes or fluctuations in emotions can trigger asthma attacks. Sadness, worry, excessive excitement and even laughter can also cause asthma attacks.

4. Sports factors

Exercise-induced asthma, also known as exercise-induced asthma, refers to acute, temporary large airway obstruction that occurs after a certain amount of exercise. Clinically, it is characterized by acute attacks of varying severity of asthma, which can usually resolve on its own.

5. Foggy and dusty environment

Smoking, special smells (bad smells, fireworks, mosquito coils, car exhaust, campfire smoke, etc.), cooking fumes, etc. can all be triggers for asthma. In my country's summer, DDT and pesticides can also aggravate the patient's condition.

In addition to the above, you should also be careful when entering and leaving air-conditioned rooms with large temperature differences, because children are weak in nature. The sudden change of temperature will cause children to catch a cold and have a fever, thereby inducing asthma and bronchitis. Especially now that it is summer, I hope mothers can pay more attention in the process of raising their children.
