Responses To Allergies
Allergy is identified as an exaggerated reaction of the immunity process to foreign bodies and substances that are not harmful to normal non-allergic individuals. The response by the immune system is exaggerated since it treats these foreign bodies as threats to the health of the body, instead of discarding and eliminating them love it normally would. This reaction is feasible if a particular response of the immunity process is activated.
The mechanism of allergies starts with the so-called exaggerated reaction of the immunity process to antigens. Antigens are special substances that trigger the immune system to discharge its antibodies. Once an antigen invades the body, the immunity process will try to work out the nature of antigen by identifying whether it is dangerous or not. In people who have not developed allergies, all antigens are not harmful.
Even so, for people who had antigens which underwent previous sensitization, selected antigens are treated by the body as threats. Among allergic people, the encroachment in an antigen will trigger a series of immune response called allergic cascade. The outcome of which are allergic reactions and signs characterizing the specific allergy or the specific body part tormented by the antigen.
The antigen to which an individual is allergic to is called allergen which comes in styles of animal dander, foods, drugs, chemical substances, pollens, dust mites and others.
Allergens can penetrate the body through various access points. These entry points are basically distinguished by the nature of the allergen. For instance, nasal passages are the passageways for pollens, dust mites, dust, molds and various minute objects.
Allergens can also impact the body, but do not necessarily have to enter the inner body, through the contact with the skin or mucous tissue layers. Topical chemicals and substances are oftentimes the culprits of allergic responses on the skin. This allergic reaction differs with other allergic responses since it only triggers cells of inflammation which are found on the superficial layers of the skin and not the specific antibody that reacts to allergens- the IgE.
Even so, for some substances, contact does not end with the skin, they often times seep through the underlying structures to cause more life-threatening allergic responses. There are likewise irritants that are injected to the body. These typically include materials that are injected mechanically or chemicals that insects carry. Lastly are the allergens that are ingested which compose of a variety of food that typically trigger allergic responses among humans, treatments and drugs. In over sensitive individuals, even water components may pose as allergens.
The allergic cascade happens in three phases. It starts with the invasion of a common substance of the body’s system. If the immunity process detects it as harmless, it will not respond aggressively, leading to the antigen’s elimination. All the same, if the immune system detects it as a threat, it will make IgE or immunoglobulin E, an antibody that reacts to allergens, in massive quantities. IgE will then plot the allergen as harmful and will build up immune side effects in succeeding encounters.
After sensitization comes another encounter with the antigen. By this occasion, your body has already developed exaggerated responses. Because of the discharge of some chemicals into the blood stream as it attempts to eradicate the antigen, the body will feel the signs of the allergy.
These signs are the natural consequences of the immune response.
