Allergy: Frequently Asked Questions
What is an allergy?
An allergy is an abnormal reaction to ordinarily harmless substances. These substances, called allergens, may be inhaled, swallowed or come into contact with the skin. When an allergen is absorbed into the body it triggers white blood cells to produce IgE antibodies. These antibodies attach themselves to mast cells causing release of potent chemical mediators such as histamine, causing typical allergic symptoms.

An allergy is the body's immune system response to specific elements in the environment. Children with allergies react to certain substances in their everyday environment, which usually don't cause reactions in other children. About 20 percent of Americans-one in every five adults and children-have allergies, including allergic asthma. About 80 percent of children with asthma have allergies. Food allergies occur in 8 percent of children younger than age six.

An allergy is a sensitivity to a normally harmless substance, one that does not bother most people. The allergen (the foreign substance that provokes a reaction) can be a food, dust particles, a drug, insect venom, or mold spores, as well as pollen. Allergic people often have a sensitivity to more than one substance.

An allergy causes the body to 'overreact' to substances that are normally harmless. The body regards those substances as harmful intruders against which it must arm itself. Allergens enter the body by inhalation or via food, skin contact, administration of medicines or insects.

Is allergy hereditary?
Allergic diseases can develop at any age and heredity plays a key role in who will develop it. If one parent has an allergic disease, the estimated risk to the child to develop allergies is 25 per cent and to 50 per cent if both parents have allergies. Also, the allergic mother is more likely to transfer the disease to the child as compared to an allergic father

Is an allergy dangerous?
Most allergies are not dangerous. An anaphylactic shock reaction, on the other hand, is. It may even be life-threatening, but this severe form is fortunately rare. Although most allergies are not dangerous, they are often a great nuisance. Severe symptoms may cause great discomfort during day-to-day activities, such as cycling, driving or sports. Fortunately, there are many effective treatments nowadays.

What Is Allergy Immunotherapy?
Immunotheraphy, also known as Allergy Immunology, is a procedure in which an allergy patient receives very small dosages of an allergen, administered over a long period of time in order to increase that person's tolerance towards the allergen and decrease the person's symptoms. Immunotheraphy is usually recommended to people who have year round allergies or those where normal medication does not or hardly works. It works best for those with allergies for inhaled allergens( like pollen) or insect stings. ...

What is a food allergy?
As with any allergy, a food allergy develops when the immune system attacks a normally harmless substance and creates specific antibodies for this substance. From this point on, whenever the food allergy sufferer eats the food to which they're allergic, the antibodies respond by releasing histamine, which causes allergic symptoms to appear.
Source: www.achooallergy.com
People with food allergies have immune systems that react to harmless substances found in food and drink. These substances are called allergens. When people have an allergy, there are antibodies to the allergens in their blood and throughout their body. When that person eats a food to which they are allergic, the food allergens react to antibodies on cells releasing chemicals. Any food can cause an allergic reaction, but only eight foods cause nine out of ten reactions. ...

The immune system mistakenly believes that a harmless substance, in this case a food item, is harmful. In its attempt to protect the body, it creates specific antibodies to that food. The next time the individual eats that food, the immune system releases massive amounts of chemicals and histamines in order to protect the body. These chemicals trigger a cascade of allergic symptoms that can affect the respiratory system, gastrointestinal tract, skin or cardiovascular system. Related Links: http://www.foodallergy.org

People with ragweed allergy, for example, may experience itching and tingling of the mouth, tongue, and throat after eating watermelon, cantaloupe, banana, or cucumber. OAS is due to cross-reactivity between certain pollen proteins and food proteins, meaning that the immune system cannot distinguish between the two different proteins. ...

What is allergy testing?
What is allergy testing? If you are "allergic", you are reacting to a particular substance. Any substance that can trigger an allergic reaction is called an allergen.

Allergy tests are designed to gather the most specific information possible so your doctor can determine what you are allergic to and provide the best treatment. Top 33

What is silver allergy?
Silver's allergenic potential is extremely low. There exist only a few recorded cases of allergy in people who have been in constant contact with high concentrations of silver – for example silversmiths or silver miners. Most people who believe they have a silver allergy actually have an allergic reaction to nickel, because silver used for jewellery often contains nickel. Standardized testing confirmed that the Elastoplast Silver Healing™ line with silver technology is skin-friendly.
