A food allergy test is usually a last resort when battling with a nondescript list of symptoms or a mystery diagnosis. The field of food allergies is still emerging, with new conditions being attributed to it all the time. Every person is different, and thus reacts differently. People who have the same symptoms may have a different allergy, and those with the same allergy may have vastly different symptoms. When you think of a food allergy, what comes to mind? Hives? Swelling? Itchy throat and cough? These are all common symptoms of the most prevalent type of food allergy. As we will discuss later, there are many different types of reactions that affect our bodies in subtle ways that we may not initially associate with allergies. Medicine is starting to see a link with allergies, food allergies in particular, with effects on the central nervous system. This intricate, interwoven web is showing us connections to fatigue/chronic fatigue, behavioral problems, psychiatric problems, depression, and anxiety/panic attacks.
