Allergy: A Brief Explanation |
Allergy is exaggerated and a substance that causes an allergic reaction called allergens. Such common allergens that may result to an allergy exposure are the plant pollens from grasses, trees, or ragweed; tiny scales shed from the feathers, hair or skin of various animals; arachnids and insects, such as house dust mites, bees, and wasps; and drugs, such as penicillin. Hard-shelled animal (e.g. .lobster, crabs, and shrimps), eggs, fish, milk, peanuts, soybeans, tree nuts, and wheat are among the most common food allergies. Researchers estimate that at least 24 million people in the United States suffer from allergies, about 19 percent of the population. Allergy affects the immune system. Immune System is a group of cells, molecules, and organs that act together to protect our body against foreign invaders that may cause disease, such as bacteria, viruses, and fungi. The health of our body is dependent on the immune system’s ability to recognize, drive away and destroy these invaders. Upon first exposure to an allergen, no allergic symptoms may develop. When the person is exposed to same substances at a later time, the allergic reaction against the lgE (immunoglobulin E) antibodies may activate the allergen. Here are some allergy symptoms:
There are also seldom incidents of allergic shock and death.
