In 1999, WHO proposed that the treatment of allergic diseases should include four aspects: patient education, identification and avoidance of exposure to allergens, drug therapy, and immunotherapy. 1. Patient education: A point that many clinicians often overlook. When I decide to give a patient a certain treatment and to obtain his or her consent, the first thing I should do is to make the patient trust me. For patients with allergic rhinitis, I often talk to them a lot. I will do my best to let the patients understand why their disease occurs, the incidence situation, what treatments are available, what treatments are right and necessary, what treatments are wrong, what will result from not treating, etc. As there are individual differences in allergic diseases, when patients understand their diseases, the self-management of patients during treatment will be more thoughtful and timely than ours. 2. Environmental control, i.e., identifying and avoiding exposure to allergens: Several hospitals around me do not have otolaryngology departments that conduct allergen testing and immunotherapy. For patients with allergic diseases, although some allergens cannot be avoided, clear allergens and the right intervention can often lead to symptom reduction or medication reduction; 3. (Only the principle, the specific types and methods are known, but do not advocate local or systemic injection of long-acting hormones) 4, immunotherapy: After our observations, for patients with allergic rhinitis who are indeed type I allergic reactions and have clearly identified allergens, a three-year immunotherapy is effective.
