Food allergy refers to an abnormal immune response to allergens present in food. Symptoms caused by this abnormal immune response vary widely, may affect many organ systems, and in rare cases are life-threatening.
Symptoms may be acute and may be associated with food allergies, such as itching in the mouth, throat and other adjacent areas, swelling of the face, tongue and lips, difficulty swallowing or breathing, nausea and vomiting, abdominal pain and skin reactions like urticaria. Sometimes food allergies may show atypical performance, which may not be easily attributed to food allergies. An example of this is a neuropathy caused by an allergic reaction to food. In this case, the affected person may have a sensory manifestation of peripheral neuropathy, such as numbness, acupuncture, burning sensation, pain or loss of sensation in one or more areas of the body. Affected people may also develop motor symptoms in the form of weakness in one or more muscle groups. Although peripheral neuropathy, which is a characteristic feature of food allergy, has been documented, it is generally not easy to attribute peripheral neuropathy to food allergy. However, finding food allergies is critical to the cause of this peripheral neuropathy, which can change your life because neuropathy is often frustrating, not only because of symptoms, but also because it does not respond to any other treatment. The only treatment in this case is to avoid allergens.
Correct identification of food allergies may change a person's life, but in all cases this may not be easy. In most cases, this association may be obvious, and one person may clearly remember the symptoms after eating a particular food. However, in many cases, especially when the symptoms are not acute, the association between food allergies and symptoms may present difficult diagnostic challenges. Various allergy tests are used to test patients' allergies. In the skin prick test, a suspected allergen was introduced into the skin and the reaction was noted. Blood test such as RAST [Radio Allergo Sorbent Test] can also be used to detect specific IgE antibodies against allergens. Both tests can only detect IgE allergens, but not other allergens. In another test called the Food Challenge Test, the patient was given a substance suspected of being an allergen and then noticed the reaction. However, this can usually happen, but allergens may not be recognized, especially in atypical manifestations such as neuropathy. In this case, the only remaining option is a hit and test strategy in which common suspected allergens are removed from the diet and the response is noted within a few weeks. If the person's symptoms are alleviated, the removed substance is likely to become an allergen.
