Possible Causes of an Allergic Reaction
It is still not fully clear why certain individuals are more susceptible to allergic reactions to others. This condition tends to run in families, meaning it may be passed down from parents to children. If you have a family member with allergies, you may be at a higher risk for developing an allergic reaction. Several substances, also known as allergens, are known to trigger an allergic reaction. These include mold, pollen, dust mites, insect strings, dog or cat dander, foods, medications, and plants. [2]
