WHAT IS AN ALLERGY?
When most people think of an allergy, they think of the sneezing, congestion, and itchy eyes caused by pollen. In fact, allergies can be caused by just about any substance that you inhale or swallow, or which touches your skin. Your body’s immune system is designed to attack harmful substances like bacteria and viruses. But with allergies, your body launches an assault on substances that are basically harmless — such as pollen, mold, dust mites, pet saliva and dander, and even medications and insect sting venom. Allergies are extremely common. About 40% of the population suffers from them, leading to millions of missed work days and school days each year. Annual medical costs exceed $4 billion. Not only do allergies cause a range of annoying symptoms such as sneezing and itchy eyes, but they can aggravate or trigger other conditions such as asthma, sinusitis, and ear infections. For example, when allergies cause inflammation in your nasal passages, the opening to your sinuses can beco
An allergy is an abnormal reaction to an ordinarily harmless substance called an allergen. When an allergen, such as pollen, is absorbed into the body of an allergic person, that persons immune system views the allergen as an invader and a chain reaction is initiated. White blood cells of the immune system produce IgE antibodies. These antibodies attach themselves to special cells called mast cells, causing a release of potent chemicals such as histamine. These chemicals cause symptoms such as a runny nose, watery eyes, itching and sneezing. • What are some common allergens? People can be allergic to one or several allergens. The most common include pollens, molds, dust mites, animal dander (dead skin flakes from animals with fur); foods; medications; cockroach droppings and insect stings. • Is there only one type of allergic reaction? Allergic individuals can exhibit a variety of reactions depending on the allergen and the way it was absorbed into the body. Seasonal allergic rhinitis
How do you beat your allergies? I would like to get any tips or some kind of suggestions on some treatment maybe. Do you have anything to share? Please let me know, I am going to try one allergy treatment medicine, and I will update you here about how it goes 🙂
An allergy is a hypersensitivity, or abnormal reaction, to a substance that is ordinarily harmless to most people. Substances which cause allergies are called allergens or antigens. Animal allergens, pollen, house dust, molds, foods and medicines are only a few substances that trigger allergic episodes. Fabric softeners, soaps, detergents, perfumes, scented cosmetics, insecticides, cleaning fluids, paints, tobacco, and even fumes given off by vehicles and industry can set off allergies. In short, anyone can be allergic to anything.
[Section Updated: 2/97] Allergists often point to medical tests which find IgE or IgG or other test detectable substances in the blood stream, or by skin reactions, when defining a source of a substance sensitivity. Clinical Ecologists, or Environmental Medicine Practitioners, on the other hand, often define an allergy as any environmental stimulus that produces an undesired symptom or an intolerance. The subtle definition difference is not so subtle when the doctors choose techniques to find sensitivities to foods and chemicals. The clinical ecologist may use the allergist’s blood and skin testing, but if they haven’t been useful in resolving the problems, he will go on with less conventional means to find the root of the problems. The traditional allergist is out of his league when blood tests and skin tests do not pinpoint a problem. In this FAQ we will use the latter, “broad”, definition as it better covers chemical and food problems. That is, any environmental stimulus that produc
