Definition: The word "Allergy" in English comes from Ancient Greek, meaning "to feel." It is a term used to describe an allergic reaction or allergy, which can affect the body's ability to fight off infections or diseases. Definition: Allergies are reactions that occur when your immune system mistakenly attacks healthy tissues and cells. This process of identifying a specific allergen as harmless (allergin) or dangerous (allergic) can be triggered by environmental factors like pollen, dust mites, pet dander, nuts, peanuts, gluten, rice, milk, eggs, wheat, soy, celery, broccoli, tree nuts, fish, shellfish, and even some food products. The body's immune system attacks these harmless components and causes inflammation in the body. This can lead to a range of symptoms including sneezing, runny nose, itching, cough, diarrhea, fever, and difficulty breathing. It is important to note that allergies are not contagious; however, many people experience allergic reactions in different ways depending on their specific triggers. The word "allergy" comes from the Greek word "Allergene," which means "a substance or material that attracts an immune system." This term was first used by Roman physicians in the 3rd century BCE to describe an inflammatory reaction caused by a foreign substance (such as pollen, dust mites, etc.) that is not naturally present in the environment. In simpler terms, an allergy is when your body's immune response attacks something it does not recognize as its own body part. It can be triggered by things like pollen and other allergens, but it doesn't cause any disease or illness itself.
