Bronchial asthma is very common in clinical settings, mainly characterized by a reversible airflow limitation that can cause recurrent attacks of wheezing, chest tightness, and shortness of breath in patients. These attacks generally occur at night or in the early morning and can gradually ease after treatment. Bronchial asthma is mainly related to several factors, the first being environmental factors. Exposure to pollen and animal dander can trigger asthma attacks. Additionally, infections, diet, and medications are among the various factors that can provoke asthma attacks.

Can bronchial asthma be cured?

Bronchial asthma, to this day, cannot be completely cured. Many places claim under the guise of traditional Chinese medicine or ancient secret recipes that bronchial asthma can be fully cured, but these are false advertisements. So far, bronchial asthma is a manageable disease. Being manageable means that it can be treated; standardized treatment can make its recurrence quite rare, but it still cannot be completely cured. This means that once someone has bronchial asthma, they must understand that it is a lifelong disease, potentially recurring throughout life, and they need to manage it long-term.

Is bronchial asthma airflow limitation reversible?

The airflow limitation in bronchial asthma is completely reversible, which is related to the pathophysiological mechanisms involved in the occurrence of bronchial asthma. Bronchial asthma is a chronic airway inflammation involving multiple inflammatory cells. When this airway inflammation occurs, there can be edema of the airway mucosa as well as spasm and contraction of the smooth muscles outside the bronchi. However, this inflammation and smooth muscle spasm are reversible through medication or spontaneous improvement. Thus, many patients with mild asthma can achieve symptom relief without medication. In the case of some severe patients, even though the airflow is restricted, it can be reversed with the use of medications, and generally, the recovery is very quick.

How to completely cure bronchial asthma?

How can bronchial asthma be cured? First, we need to recognize that once bronchial asthma is diagnosed, it is a lifelong disease and is recurrent throughout one's life. So far, it cannot be cured. Many people on television or in magazines claim that traditional Chinese medicine, ancient secret recipes, or other means can cure bronchial asthma, suggesting various treatments. However, these are false advertisements and should not be trusted. Bronchial asthma can be controlled, meaning that it is currently incurable and can only be managed with medication. There are now many treatment options for bronchial asthma. As long as patients seek standardized treatment at legitimate hospitals, the majority of those with bronchial asthma can receive proper treatment and management.

In clinical practice, the following categories of bronchodilator drugs are mainly used: The first is adrenergic receptor agonists, such as salbutamol and terbutaline; the second is anticholinergic drugs, mainly tiotropium bromide; the third category is xanthine drugs, which can include aminophylline or doxophylline. Additionally, glucocorticoids can be used for pharmacological treatment. If the patient still has recurrent attacks after systemic treatment, hospitalization is recommended for further management.

What position should be taken for bronchial asthma?

The choice of lying position for bronchial asthma depends on the specific condition of the disease. During the remission phase of asthma, a free lying position is suitable. If it is a mild attack phase, a flat lying position can be taken. If symptoms such as chest tightness become prominent during an attack, a semi-sitting position is advisable. For asthma patients experiencing significant chest tightness and breathing difficulties during an attack, or if they are in a persistent state of asthma, then a sitting position is often required. Patients may experience severe sweating, be unable to speak, and even suffer from hypoxia during such times, which can be extremely distressing.
