The incidence of bronchial asthma is increasing year by year and is attracting more and more attention. What are the clinical symptoms of bronchial asthma? The typical symptoms of bronchial asthma are episodic dyspnea, wheezing, chest tightness, coughing, etc., and a typical asthma attack often comes with wheezing sounds. Some patients have atypical symptoms, which may primarily present as just one symptom, such as cough or chest tightness alone, known as atypical asthma. However, whether it is typical or atypical asthma, the principles of treatment are the same. It is essential to cooperate with the doctor to control the disease, improve symptoms, and enhance the quality of life.

Can bronchial asthma be inherited?

The etiology of asthma is still very unclear, but genetics may indeed be related to bronchial asthma to some extent. Currently, a lot of research data indicates that the incidence rate of bronchial asthma is higher among the relatives of patients than in the general population, and the closer the familial relationship, the higher the incidence rate and potentially more severe the condition could be. In layman's terms, this means that if our parents have bronchial asthma, then the likelihood of their children having bronchial asthma is higher than in the general population. However, this is not absolute; it does not mean that if a parent has bronchial asthma, their children will definitely have it. The relationship is not very certain, and the genes related to bronchial asthma are also not very clear at present. Bronchial asthma is also related to many other factors.

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.

Symptoms of bronchial asthma cough

Bronchial asthma, commonly referred to as asthma, often results in symptoms such as wheezing, shortness of breath, chest tightness, and coughing in patients. However, these symptoms do not always appear simultaneously in an individual. It's possible for a single symptom to serve as the initial manifestation of bronchial asthma. For example, the condition may present solely as wheezing, chest tightness, or, notably, as coughing, where it is the only symptom. The characteristics of asthma-related coughing primarily include a certain rhythmic pattern, typically worsening during early morning or late night, and it can easily lead to coughing up blood. Additionally, the coughing may begin and end abruptly and can be triggered by exposure to cold air or strange smells, followed by spontaneous improvement after a period. These are distinctive features of bronchial asthma coughing.

What medicine is used for bronchial asthma?

Bronchial asthma, although common, currently has no specific treatment. The primary aim of medication is to control symptoms. There are two main types of medications used to treat asthma: one type is known as bronchodilators, commonly including receptor agonists, anticholinergics, and theophylline. The other type is anti-inflammatory drugs, commonly including corticosteroids, leukotriene modifiers, sodium cromoglycate, nedocromil sodium, and ketotifen. (Medications should be used under the guidance of a doctor, according to specific circumstances.)

Symptoms of bronchial asthma

The most common symptoms of bronchial asthma are episodic difficulty in breathing, which can also manifest as episodic chest tightness and coughing. During an asthma attack, there will be accompanying wheezing sounds. If the patient is more severe, they may be forced to sit up to breathe during episodes of breathing difficulties, exhibiting orthopneic breathing. Some patients may experience a dry cough or cough up a large amount of white foamy sputum. In severe cases, symptoms of hypoxia such as cyanosis of the lips and nail discoloration can occur. Asthma attacks are generally acute, with symptoms appearing within minutes, but they can also begin more slowly, worsening over several hours or days. Asthma generally relieves itself, or even after relieving, it may recur, typically worsening during the night.
