What Happens In the Body During Allergic Reactions?

The human body is made with different kinds of immunity, which protects it from anything that could harm the body. During an allergic reaction, the immune system erroneously believes that what have entered the body are harmful, thus producing antibodies called IgE (immunoglobulin E) antibodies to protect itself from the harmful element. It then circulates through the blood forming IgE’s, which are specific to something as light as food. After this food-specific IgE is formed, it attaches itself to the mast cell which in turn produces chemicals into the bloodstream. These chemicals include what we call Histamine which acts on the parts of the body near to the mast cell attached with IgE antibodies. Examples are nose, eye, throat, skin, lungs, or gastrointestinal tract. This causes the distinctive allergic reactions.

Take note that these cells are present in all body tissues. Once the body detects the food which it recognizes as the antibody, the body’s immune system will again fight the food off by going through the whole process of the allergic reaction.

            While other allergic reactions could be life-threatening such as anaphylaxis or asthma some could be just a simple rash, itchy eyes or sneezing. The reaction depends on the person and is known to be unpredictable.
