An allergy is a hypersensitiveness disorder of immune system, which includes excessive response of the immune system. When an individual’s immune system responds to generally safe substances in the atmosphere, an allergic reaction takes place. An allergen is the stuff that the immune system detects as a certain ‘intruder’. Allergens are unknown to the human organism and are the reason of an allergic reaction.
Allergies carry out one of the four hypersensitivity forms, and are formally named type I (immediate) hypersensitivity. Each of allergic conditions is specific due to an exorbitant activation of particular white blood cells known as mast cells and basophils by an Immunoglobulin E antibody (IgE). These reactions may cause a phlogistic response varying from inconvenient to life-threatening and that of course affects the quality of life of people prone to allergies. Allergy medications list near at hand for the allergics may be a real life-savior, because knowing what to use against yet another allergy attack can be very helpful.
The most common causes of allergies are dust mite, different kinds of food, pollen, insect stings, animal dander, medicaments, mold and latex. There is an additional risk of getting allergic reactions with allergy history in close relatives.
The most typical symptoms of an allergy usually develop on the skin, in the nose, sinuses, throat, eyes, lungs, ears and on the lining of the stomach. Allergies may cause asthma symptoms for some individuals. In especially serious matters anaphylaxis – a life-threatening condition – may occur.
In terms of treatment allergies can be quite well managed if taken under control in time. It is important to remember, that allergies may appear and pass at any age. In order to diagnose allergic conditions there is a wide range of tests that can be run.
Of course, there is a great deal of effective allergy medications, some of which have side effects, others (the new ones) don’t and are completely non-drowsy. Therapy for allergies implies excluding established allergens, steroids which alter the immune system generally and decongestants as well as antihistamines which decrease allergy symptoms. Most of these drugs are used orally, even though epinephrine that treats anaphylactic reactions is used through injections. Immunotherapy utilizes injected allergens to desensitize a response of the human body. There are a lot of resources on this subject to which evidence-based medicine often refers. The brands of allergy medications in such resources may differ, however the effect will mostly remain the same.
