Generally, exogenous asthma attacks have no obvious prodromal symptoms. However, if patients experience discomfort such as cough and chest tightness after exposure to allergens, it may be an allergic reaction. Exogenous asthma refers to bronchial asthma caused by environmental factors, such as pollen, dust mites, or cold air stimulation, which can induce the disease. This type of asthma generally has no obvious predisposing factors, often occurs suddenly when it occurs, and has certain seasonal and geographical characteristics. Therefore, in clinical practice, the treatment of such patients is mainly based on prevention, and avoiding inhalation of allergens and sensitizing substances is one of the key measures. Some patients may experience some symptoms before an exogenous asthma attack, such as skin itching, sneezing, or runny nose. This is because the body has an immune response to certain specific allergens. However, these symptoms do not necessarily appear in all patients, and they cannot be used as a standard basis for judging whether they have exogenous asthma. If you suspect that you have exogenous asthma, it is recommended to seek medical attention promptly for professional diagnosis and evaluation. The doctor will determine whether there are signs of the disease based on medical history inquiries and physical examination results, and further formulate corresponding diagnosis and treatment plans. At the same time, regular follow-up visits are also necessary to monitor changes in the condition and adjust the treatment plan.
