The causes of bronchial asthma are actually not very clear at present, but current research shows that bronchial asthma is mainly caused by genetic and environmental factors. Genetic factors are relatively easier to understand, meaning if parents have a history of bronchial asthma, then their children, grandchildren, and other blood relatives may have a higher chance of developing bronchial asthma than the general population. Additionally, bronchial asthma is also related to environmental factors, such as air pollution, smoking, dust mites, pollen, etc.

Does bronchial asthma spread?

In some families or among relatives, multiple people may have bronchial asthma. If multiple members suffer from bronchial asthma, is it because they have infected each other? Actually, that's not the case. Bronchial asthma is not contagious. The reason why multiple family members or relatives have bronchial asthma is due to genetics. The closer the familial ties of asthma patients, the higher the incidence of the disease. The more severe the patient's condition, the higher the incidence among their relatives. Therefore, asthma is related to genetics but is not contagious.

How to use diet to supplement for bronchial asthma

Generally speaking, for bronchial asthma, especially milder cases or those with rare occurrences and short duration, there is no need to deliberately seek dietary supplements. Moreover, since bronchial asthma is a type of allergic disease, caution should be taken with dietary supplements to ensure there are no allergies to certain foods or herbal remedies. For chronic, recurrent asthma, traditional Chinese medicine often attributes it to kidney deficiency or a deficiency in both the lung and kidney qi, where the organs fail to properly grasp the qi. In such cases, dietary supplements that originate from both food and medicine can be helpful. Examples include cordyceps duck soup, walnut kernels, cordyceps, and mulberry seeds. These substances can support kidney function and help manage asthma to some extent. (Note: The use of these substances should be guided by a professional doctor.)

Is bronchial asthma curable?

Bronchial asthma is treatable, although so far we have not found a cure for bronchial asthma, bronchial asthma can be well controlled in most patients if treated in a standard way at regular hospitals, preventing recurrent asthma attacks. However, if the treatment of bronchial asthma is unstandardized, or if one relies on folk remedies or traditional secret recipes and does not receive standardized treatment at a regular hospital, it may lead to recurrent asthma attacks and extremely poor prognosis.

Does bronchial asthma have wheezing sounds?

During an acute attack of bronchial asthma, patients often have wheezing sounds in their lungs, but it's important to note that some patients may not exhibit wheezing, such as those with chest tightness or cough variant asthma, who only show symptoms of chest tightness and typically do not have wheezing on auscultation. However, administering inhaled corticosteroids and bronchodilators can relieve their condition. Additionally, during a severe acute attack of bronchial asthma, severe airway spasms can occur, leading to a situation where the patient might not have any wheezing sounds, a condition referred to as "silent lung." In such cases, patients often experience difficulty breathing or even respiratory distress, which is usually quite serious and requires active intervention.

The cause of airflow limitation in bronchial asthma.

Bronchial asthma airflow limitation is a respiratory physiological feature of our bronchial asthma, and its limitation is mainly related to the pathophysiological mechanism of asthma. Asthma is a chronic airway inflammation involving multiple cells caused by various reasons. When inflammation occurs, the mucosa will become edematous, and the smooth muscle outside the airway will also spasm and contract. Therefore, the airflow cannot smoothly enter and exit the bronchi, leading to the manifestation of airflow limitation in the bronchi. Thus, in the treatment of asthma, we need to use some bronchodilator drugs, as well as some anti-inflammatory drugs, so as to comprehensively control the patient's symptoms.
