alérgicos

Alérgicos refers to individuals who experience allergies. An allergy is a hypersensitive immune system response to substances that are generally harmless to most people. These substances, known as allergens, can include pollen, dust mites, certain foods, animal dander, insect venom, and medications.

When an allergic person encounters an allergen, their immune system mistakenly identifies it as a threat. This triggers the release of chemicals, such as histamine, which cause the symptoms of an allergic reaction. These symptoms can vary widely depending on the allergen and the individual, and can range from mild to severe. Common symptoms include sneezing, itching, runny nose, watery eyes, skin rashes, hives, swelling, and difficulty breathing. In some cases, severe allergic reactions, known as anaphylaxis, can be life-threatening.

Diagnosing allergies typically involves a medical history, physical examination, and allergy testing, which may include skin prick tests or blood tests. Management of allergies often involves avoiding known allergens, taking medications like antihistamines or corticosteroids to alleviate symptoms, and in some cases, immunotherapy (allergy shots) to desensitize the immune system. Awareness of allergens and prompt medical attention are crucial for individuals with allergies.
