Causes of asthma

Asthma actually often occurs in life, usually caused by respiratory tract infection, which has a great impact on people's daily life. Especially when asthma attacks cannot be handled and resolved in time, it may even be life-threatening. Therefore, the prevention of asthma also needs to be taken seriously. So let's take a look at the causes of asthma.

No matter what factors cause asthma, it will endanger people's physical health, life and work. Moreover, this disease does not discriminate at any age, even children are susceptible to it, so we must attach importance to scientific treatment to effectively prevent asthma.

Infection: Respiratory tract infection, especially respiratory viral infection, is the main cause of childhood asthma. In recent years, most studies have shown that viruses are the main cause of respiratory tract infection, and bacterial infection does not play a major role in either asthma attacks or secondary infections of bronchial asthma. Different ages have different pathogens. Preschool children are often infected with rhinovirus, mycoplasma pneumoniae, parainfluenza virus, and respiratory syncytial virus; preschool children are often infected with respiratory syncytial virus, parainfluenza virus, and adenovirus; adolescents are often infected with mycoplasma pneumoniae, rhinovirus, parainfluenza virus, and respiratory syncytial virus.

Allergic mites: Children are more allergic to mites than adults, and the symptoms often occur at night. The characteristic of asthma caused by allergic mites is that the symptoms appear early. According to a survey of 143 children with asthma, 61.5% of them had their first asthma attack within 3 years old, indicating that this kind of infant asthma can be allergic or will turn into allergic asthma in the future.

Other causes: non-pathogenic bacteria (streptococci, Neisseria), fungi, milk, eggs, pollen, cotton wool, silk, animal hair, feathers, moths, malarial parasites and mood changes (such as crying and laughing, nervousness and fear, etc.) can all cause asthma in some children.

The above is an introduction to the causes of asthma. After understanding it, we found that there are many factors that can cause asthma. In addition to some respiratory infections, some diets or allergies in life may lead to asthma attacks, so everyone must pay attention to prevention.
