What Is An Allergy?

An allergy is a condition in which the immune system reacts abnormally to usually harmless substances known as allergens, such as dust, pollen, certain foods, or medications. This overreaction can trigger symptoms like sneezing, itching, skin rashes, swelling, or breathing difficulties. Allergies can range from mild to severe and may require proper diagnosis and management to prevent complications and ensure better quality of life.

What Causes Allergies?

Allergies are caused when the immune system mistakenly identifies harmless substances—such as dust, pollen, pet dander, certain foods, or medications—as harmful. This triggers an overreaction, leading to the release of chemicals like histamine, which causes symptoms such as sneezing, itching, rashes, or breathing difficulties. Both genetic factors and environmental exposure can increase the likelihood of developing allergies.

What Are The Symptoms Of Allergies?

Allergy symptoms can vary depending on the trigger and severity, but commonly include sneezing, runny or blocked nose, itchy or watery eyes, skin rashes, itching, coughing, and breathing difficulties. In some cases, allergies may also cause swelling or more severe reactions that require immediate medical attention. Early identification of symptoms helps in effective management and prevention of complications.
