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.

Bronchial asthma needs attention

In clinical settings, bronchial asthma is mostly allergic asthma. Therefore, in terms of diet, attention should be paid to avoiding foods like fish, shrimp, chili peppers, and other foods that are likely to trigger allergies. Instead, consume more bland, soft, and easily digestible foods. Regular physical exercise should also be performed, especially outdoor aerobic and endurance exercises, to enhance the body's immune capabilities. Furthermore, during the flu season or the pollen-heavy spring season, going outdoors should be avoided to prevent triggering asthma attacks. It is advisable to check for allergies to specific substances and avoid contact with them thereafter.

Symptoms of bronchial asthma cough

Bronchial asthma can also manifest as a disease primarily characterized by coughing, which we call cough-variant asthma. It does not necessarily exhibit typical symptoms of bronchial asthma such as wheezing, shortness of breath, and chest tightness; it manifests solely as coughing. This type of cough generally occurs more frequently in the early morning and at night, characterized primarily by a dry cough without mucus. If the coughing is severe, some chest tightness may occur, accompanied by symptoms such as an itchy nose, itchy throat, or the presence of hives, an allergic condition, which is different from ordinary coughs. Therefore, when these characteristics are present, attention should be paid to whether it is combined with bronchial asthma, rather than just a simple cold or bronchitis manifestation.

Does bronchial asthma cause coughing?

Bronchial asthma is a common clinical disease, with main symptoms including paroxysmal wheezing, chest tightness, and difficulty breathing, etc. So, does bronchial asthma also present with coughing symptoms? Indeed, bronchial asthma can also manifest with coughing symptoms, especially the atypical cough variant asthma which is primarily characterized by chronic cough. Moreover, the symptoms of cough often occur at night or early morning, and the coughing can be quite significant, severely affecting the patient's sleep quality. If cough variant asthma is suspected, it is important to visit a hospital in a timely manner for relevant examinations and the treatment principles are the same as for typical asthma.

Prevention and Treatment of Bronchial Asthma

The prevention and treatment of bronchial asthma mainly involve the following aspects: First, eliminating the causes and triggers of the disease; second, preventing diseases and pests such as allergic rhinitis and gastroesophageal reflux disease; third, immunomodulation; fourth, routinely checking if inhaled medications are used correctly; fifth, education and management of asthma patients, mainly allowing them through long-term, appropriate, and sufficient treatment to fully and effectively control asthma attacks. Additionally, understanding individual differences in asthma triggers to avoid occurrences, learning patient self-monitoring of disease progression, mastering the use of inhalers and peak flow meters, and educating patients on simple self-help methods are essential. It's important for patients and doctors to jointly develop a plan to prevent asthma attacks and maintain long-term stability. These are the basic elements of the prevention and treatment of bronchial asthma.

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.
