Explore how allergies impact overall health, including common triggers, symptoms, diagnosis methods, and treatment options to improve quality of life.

The immune system's primary role is to protect the body from harmful bacteria and viruses. Occasionally, it overreacts to harmless substances known as allergens, resulting in allergic reactions. Individuals with a genetic predisposition to allergies are called atopic or allergy-prone. Non-allergic people typically do not respond to these substances. Common allergens include medications, certain foods, pollen, dust mites, pet dander, and mold spores. Exposure triggers Immunoglobulin E (IgE) antibodies, leading to various allergy symptoms.

Dust sensitivity: Airborne particles and pollutants can cause reactions.

Pet sensitivities: Cat and dog fur, saliva, and skin flakes often provoke allergies.

Food sensitivities: Eggs, nuts, shellfish, and soy can lead to mild or severe allergic responses.

Severe allergic reactions may require medical intervention. Common allergy types include ocular, skin, respiratory, latex, medication, and mold allergies. Symptoms range from skin rashes and sneezing to life-threatening anaphylaxis. Diagnosis typically involves skin tests like prick or intradermal tests to identify specific triggers. Accurate diagnosis guides effective treatment, which may include medications and allergen avoidance strategies.
