Do you need to check for allergens for allergic rhinitis?

Allergic rhinitis is a type of hypersensitivity disease. The first thing we need to know about allergic rhinitis is that it requires allergen testing. Traditionally, the diagnosis of allergic rhinitis is based on clinical symptoms, without involving etiological diagnosis. Testing for allergens is aimed at diagnosing based on its etiology. Secondly, we need to be aware of the allergens responsible for allergic rhinitis, which include food allergies and asthma-related allergies. By identifying food allergens, we can avoid consuming these substances in daily life. For instance, if one is allergic to fish and seafood, they should avoid eating these foods. Similarly, if allergic to mangoes, one should also avoid mangoes. Thus, overall, it is necessary to identify the sources of allergens in allergic rhinitis.

How to identify allergens in allergic rhinitis

Allergic rhinitis is a relatively common otolaryngological disease. The main cause is the body's immune response triggered by contact with allergens, leading to an imbalance in the immune status and causing a series of clinical symptoms. Therefore, in terms of treatment, it is first necessary to identify the specific types of allergens. Currently, there are two methods for allergen testing. The first method is ex vivo allergen screening, which involves blood tests. The second method is the skin prick test to identify specific allergens. Both methods are commonly used at present, and generally, choosing one of them is sufficient. However, a subset of patients may need a combination of both tests for a comprehensive assessment.

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.

Drug allergy symptoms

Some drug allergies can cause neurological reactions, such as dizziness and headaches. When a drug allergy occurs, immediately stop using the suspected medication, and simultaneously take anti-allergy medications such as loratadine, cetirizine, or administer diphenhydramine via muscular injection. Oral intake of compound glycyrrhizin capsules may be considered. If there is laryngeal edema, it is crucial to seek prompt medical attention at a hospital, actively manage the allergy, and severe cases may require a tracheotomy for rescue. (Specific medication usage should be conducted under the guidance of a doctor, and medications should not be used without authorization.)
