A » Allergic reactions are triggered when the immune system mistakenly identifies a typically harmless substance, known as an allergen, as a threat. This response causes the body to produce antibodies, leading to the release of chemicals like histamine. Common allergens include pollen, dust mites, pet dander, and certain foods. These reactions can cause symptoms ranging from mild irritation to severe anaphylaxis, necessitating medical attention for proper management.
