cross_allergic_reactionWith fall comes seasonal allergies for many. Unfortunately, there are a handful of allergies that can actually worsen when certain types of foods are consumed. People who are affected and have reactions to specific foods, inhalants, or other substances are actually more likely to develop an allergy to others, which is known as allergic cross-reactivity. It should be noted that these reactions can vary from being very light and hardly noticeable to heavy. Allergies are caused by the immune system’s reactions to numerous sources, including plants, moulds, latex, pollen, animal products, moulds, and certain medicines. The reason that people experience cross-reactions is that there are structural similarities between proteins, such as pollens and foods. A fairly shocking statistic, roughly 70% of individuals with food allergies also experience reactions to other allergies.

Most Common Allergic Cross-Reactions

Keep in mind that allergies affect multiple organs, including the eyes, skin, nervous, respiratory, and gastrointestinal systems. Your ENT doctor will carefully observe your reaction patterns as well as your history in order to pinpoint the specific patterns associated between allergies.

Below you will find a list of the most common cross-reactions. Please keep in mind that this list is far from exhaustive and you should contact your local ENT doctor to learn more about cross-reactions.
