1. Why do allergies occur?

1. External factors

Certain substances can cause abnormal reactions in some people's immune systems after entering the human body. These substances are called "allergens (also known as allergens)" and are the culprits of allergies.

Allergens are mostly macromolecules, such as certain proteins or peptides. Common allergens include food (wheat, peanuts, soybeans, nuts, milk, eggs, fish and crustaceans, etc., allergic diseases caused by food allergies account for about 90% of allergies), inhalants (pollen, house dust, mites, etc.), microorganisms (molds, bacteria, etc.), insect toxins, drugs (such as penicillin, sulfonamides, etc.), foreign sera and physical factors.

2. Internal factors

The internal cause is the "allergic constitution" of some people. Allergic constitution refers to the defect of the immune system of a certain group of people. Their immune system is different from that of ordinary people, so they are prone to "not distinguishing between friends and foes and attacking without reason", which leads to the occurrence of allergies.
