Allergies
Allergies are immune system overreactions to typically harmless substances, resulting in symptoms ranging from mild irritation to severe, potentially life-threatening reactions.
Resulting from an immune system mistakenly treating harmless substances as dangerous threats, these overreactions can range from minor annoyance to genuinely life-threatening medical emergencies.
An Immune System Overreaction
Allergies occur when the immune system mistakenly identifies typically harmless substances as dangerous threats, triggering an inappropriate defensive response.
A Wide Range of Triggers
Allergic reactions can be triggered by numerous substances, including pollen, certain foods, insect stings, and various environmental factors.
Symptoms Ranging from Mild to Severe
Allergic reactions range significantly in severity, from mild irritation to severe, potentially life-threatening reactions known as anaphylaxis.
Increasing Global Prevalence
Allergy prevalence has increased significantly in recent decades globally, with researchers investigating multiple potential environmental and lifestyle factors contributing to this trend.
