Allergies can be defined as malfunctions in the immune system. When the immune system struggles against a particular substance, it can have an unpleasant reaction when it is exposed to it. Contact can come about because of a number of reasons, particles of allergy-inducing substances can be found in the air and the environment, or can be contained in certain foods. These reactions can be sudden, and result in a great deal of irritation, and at times, a great deal of risk.
Usually, an allergic reaction will be quite mild. Think about you might feel in the instance of hay fever. The more gentle side-effects will symptoms similar to that of a cold. Sneezing, blocked nose, alongside itchiness around the eyes, nose and throat.
Certain alternative consequences, however, can be a little more serious. Sometimes, they can even endanger a sufferer?s life. This risk usually comes from asthma victims, or people who are allergic to specific medicines or food, like nuts or penicillin. Poisonous insects may also pose a serious threat, such as bees, whose sting can be lethal in some people.
It is possible to identify what a person reacts badly against through certain tests. If an allergy is identified, then a number of treatments can be carried out. Either the sufferer simply avoids any contact with the substance he suffers from, or specific medication such as anti-histamines or steroids may be taken to strengthen immunity.
There are a number of common causes as to how an allergic reaction might come about. This is usually to do with the person?s specific environment. Though it can also come from previous family cases and exposure to harmful substances at a younger age, such a pollution or poor diet.
Allergies can appear in early childhood or they can just be noticed at a later stage of a person?s life, without an obvious reason and without a warning. Some people might also be allergic to substances and not even know it. With allergic reactions usually being mild and easy to deal with, there is no reason to worry, however, it is always recommended that tests are carried out in order to know the substances to which the immune system reacts.
