Allergic cough is a very common type of non-infectious cough, triggered by many factors. Generally, some patients may experience this cough due to exposure to certain harmful gases or irritants, while others might react to pollen, dust mites, or animal dander. Additionally, a portion of patients could be affected by the inhalation of cold air or due to genetic factors. Since it is an allergic cough, there must be triggering factors causing it. Therefore, for allergic cough, it is essential to eliminate the allergens and appropriately administer anti-allergy medications for symptomatic treatment.

When is the best time to check for allergens in allergic asthma?

The best time to check for allergens in allergic asthma is still during an asthma attack. At this time, due to the body's strong immune response to external allergens, also referred to as a hypersensitive reaction, checking for allergens can likely yield some positive results. However, there are many methods for screening allergens, such as drawing blood to check for IgE antibodies, or using skin prick tests to assess reactions to different allergens. However, if it is during the acute phase of an asthma attack, it is recommended to use the blood drawing method, which is relatively safer. Using skin prick tests might exacerbate the patient's allergic reaction, and may even lead to an acute asthma attack, or severe asthmatic conditions. Therefore, there are significant considerations to be made when choosing different methods for allergen testing.

What are the common allergens for allergic cough?

Common allergens for allergic cough include pollen, dust, dust mites, and seafood. If a patient is allergic to these allergens, they should avoid contact with them as much as possible. It is important to strengthen the body through regular exercise and a balance of work and rest. Increase nutrition and eat more high-quality, high-protein foods to enhance the body's resistance. Additionally, keep warm and avoid catching cold, especially during the winter and spring seasons when temperature differences between morning and evening are significant, and adjust clothing accordingly. Change unhealthy lifestyle habits: do not smoke, do not drink alcohol, do not stay up late, and avoid the dangers of secondhand smoke to protect lung function.

Mite allergy symptoms

Dust mites are tiny animals that are generally invisible to the naked eye and can only be seen under a microscope. If a dust mite allergy occurs, it can cause many skin symptoms, such as acne, itching, pigmentation, or erythema, severely affecting the patient's quality of life and appearance. Therefore, if a dust mite allergy is present, it is important to pay attention to personal hygiene and skin cleanliness, and maintain ventilation in the house. Treatment can include the use of anti-allergy medications.
