This article explores the causes and symptoms of allergies, highlighting common triggers, their impact across ages, and genetic factors. It provides insight into how immune responses lead to allergic reactions and emphasizes the importance of proper management to prevent severe outcomes.

Allergy Causes and Symptoms Explained

Allergic reactions are abnormal immune responses caused by exposure to certain substances. Common triggers include pollen, insect stings, mold, medications like penicillin, pet hair, nuts, and dairy. These allergens are present in foods, air, medicines, and surroundings. When exposed, the immune system produces antibodies that lead to allergy symptoms. More than a quarter of the population experiences allergies at some stage, especially children.

Studies show about 8% of children in the U.S. suffer from food allergies, with many reacting to multiple foods and some experiencing severe reactions like anaphylaxis. Although some allergies improve over time, others last lifelong.

Adults can also develop new allergies. Reactions vary from mild to life-threatening. The National Health Society emphasizes that with proper management, most allergies can be controlled.
Triggers of Allergies
Allergies develop when the immune system confuses harmless substances like pollen, insect venom, or pet dander as threats. Genetics significantly influence susceptibility; if one parent is allergic, a child has a 33% chance of inheriting allergies, increasing to about 70% if both parents are affected.
