Facts About Allergies

What is an allergy? It is the reaction of your immune system in response to certain foreign substances that don’t cause problems to non-allergic people. Your body has an exaggerated reaction because these substances found in a regular environment are not perceived as
harmful by the immune system of other people.
While the substance doesn’t trigger any response in the case of non-allergic people, your does and a part of your immune system try to defend you by responding to a false alarm.

The symptoms of allergies differ according to the type of allergy that you have, but common reactions are headaches, sneezing, itching, a runny nose, irritations and swelling. Sometimes, people who suffer from allergies can develop asthma. Usually, allergies are not life-threatening, but a severe reaction may occur in rare cases. It is called anaphylaxis. An anaphylactic shock may include difficult breathing and swallowing, swelling of different parts of the body like lips, throat etc and also dizziness and losing consciousness.

Keeping a record of your allergy symptoms over a period of time can help you and your doctor identify which allergens cause you to overreact.The tendency to develop allergies may be hereditary, but if some members of the family have allergies, that is not necessarily a reason to develop one as well. Scientists agree that apart from family genes, environment plays an important role in having allergies.

Substances that cause reactions from your body are called allergens and they can be found anywhere, from nature to the plate that you’re eating from. Common allergens are pollen, mold, animal dander, dust, food, insect bites and medicines.If you experience symptoms that are not occurring due to some cold or flu, and you fear you might have an allergy, then go see a doctor. He will perform an allergy skin test by placing extremely small amounts of different allergens to see which one is causing a reaction. After he decides what you’re sensitive to, we’ll put together a treatment to help you get rid of the allergy. 

Allergies may be treated by medications and allergy shots for the best health advice. Medications that are used to treat allergies include pills and nasal sprays. They may control the symptoms caused by the allergy, but does not necessarily mean they are also a cure. Some may be effective against an allergy, some may not. Another way to fight against allergies are allergy shots which are part of an immuno-therapy. This means that by receiving shots of tiny amounts of allergens, the organism will develop antibodies by its own and will undergo those strange reactions of your immune system.
