The immune system has the vital job of protecting your body from invaders that can make you sick, such as bacteria and parasites. As harmful microbes are identified, the immune system initiates a complex defense response that eliminates or neutralizes the threat.
An allergy occurs when the immune system mistakes a harmless substance for an intruder. When that substance – the allergen – enters your body, the immune response automatically kicks in, producing antibodies to the allergen and releasing histamines, which cause allergy symptoms. This hypersensitive response to a harmless substance is an allergic reaction.
Some of the most common allergens include:
Allergic reactions range from mild to a severe anaphylactic reaction, which is life threatening. The thing to remember about an allergic reaction is that it can be mild the first time it occurs, then after repeated exposures to the same allergen, you can suddenly have a serious reaction.
A few common allergic reactions are:
Allergy immunotherapy desensitizes the immune system so that it stops responding to allergens. If immunotherapy doesn’t completely stop your allergic reaction, it significantly diminishes the response and gives you at least some relief from allergy symptoms. During immunotherapy, you receive gradually increasing doses of the allergens that trigger your allergic response. Over time, the immune system learns to tolerate the allergen, so it stops causing such large allergic reactions.
