Introduction
In general, allergies are not caused by a weak immune system. The immune system helps maintain internal health by quickly recognizing and responding to external threats, eliminating pathogens. When the immune system becomes dysregulated, it may mistakenly identify harmless substances as "pathogens," triggering an immune inflammatory response that leads to allergy symptoms.
Generally, allergies are not caused by a weak immune system. The detailed explanation is as follows:
Allergies are actually the result of the immune system overreacting to harmless substances. Symptoms may include sneezing, runny nose, itchy and watery eyes, skin redness and itching, difficulty breathing, and so on. For the human body, the immune system helps maintain internal health and can quickly respond to external invaders—for example, when pathogens are detected—to eliminate harmful bacteria.
When the immune system becomes dysfunctional, it may mistake harmless substances as "pathogens." For example, pollen and dust mites entering the body through breathing, or foods such as seafood and mangoes, may trigger immune inflammation and cause allergic symptoms. If people blindly enhance their immunity, such as by taking medications or other means, it may worsen allergy symptoms and even lead to autoimmune diseases.
In daily life, it is recommended to clean regularly, avoid allergens, and seek medical attention promptly if any discomfort occurs.
