Common triggers of acute asthma exacerbations include

For many elderly individuals, the cold winter months often trigger coughing. However, this is not merely a simple cough—it results from airway irritation caused by poor air quality, potentially leading to asthma attacks, which can be extremely distressing when they occur. So, what are the common triggers of acute asthma exacerbations?

Common Triggers of Acute Asthma Exacerbations

Asthma frequently begins in childhood, and affected individuals often have an allergic constitution, sometimes accompanied by allergic rhinitis. Asthma patients may be sensitive to numerous allergens and may also exhibit drug allergies. Asthma attacks commonly occur upon inhalation of irritants such as dust, house-dust mites, pollen, or pet dander (e.g., from dogs or cats). Some patients also experience food allergies; common allergenic foods include shrimp, crab, beef, lamb, eggs, and legumes. Ingestion of these allergenic foods can likewise provoke asthma attacks.

Triggers of acute asthma exacerbations fall into two categories: non-pharmacological and pharmacological factors. Non-pharmacological triggers include psychological stress, negative emotions, and physical exertion. Pharmacological triggers involve overuse of short-acting bronchodilators or improper use of inhaled medications—some patients even fail to use inhaled therapies altogether. Classic bronchial asthma is characterized by recurrent wheezing, often accompanied by other symptoms such as breathlessness; these symptoms are reversible. Importantly, diagnoses of asthma must exclude other conditions that cause chest tightness, wheezing, or shortness of breath.

Patients are advised to maintain a light, bland diet and seek prompt medical attention upon symptom onset. We hope this information proves helpful to you.
