Food allergy and intolerance testing

Understanding triggered symptoms in migraines and IBS.

Is food allergy and intolerance testing the best way to test for migraine and IBS symptoms?
This is a common question, and there is a lot of misinformation. Sometimes, finding the answer online isn’t easy and, when you find an answer, you can’t always rely on its integrity.

We are here to provide you with update research studies and information that you may want to consider before planning your next move. The role of dietary factors in the pathogenesis of irritable bowel syndrome (IBS) is still unclear.

Food elimination diets have been suggested as an effective and inexpensive therapeutic strategy in patients with migraine and concomitant IBS in past studies (1). In this study, findings indicate that food elimination based on IgG antibodies in migraine patients who suffer from concomitant IBS may effectively reduce symptoms from both disorders with a possible positive impact on the patients’ quality of life as potential savings to the healthcare system.

A study published in 2017 (2) in the Journal of Neurogastroenterology and Motility reported as serum IgG4 antibody levels to some common foods are abnormally elevated in IBS patients, suggested that an elimination diet of those foods can improve the quality of life of those patients, but further investigation of the role of food hypersensitivity in the pathogenesis of IBS must be performed using a larger group of people.

There is little dispute that certain foods can trigger migraines. These foods include chocolate, wine, cheese, citrus fruit, onions, smoked, cured, and pickled goods. It is possible to evaluate this immune response by measuring blood levels of immune globulin (IgG), which is specific to a particular food or substance.

The pathophysiology of migraine headaches is not well understood. Some evidence supports the use of IgG food sensitivity testing to determine food sensitivities and intolerances. IgG food sensitivity testing may prove beneficial for healthcare practitioners, especially for patients experiencing migraine headache symptoms. Utilising IgG food sensitivity testing to create customisable dietary recommendations for patients may allow healthcare providers to treat migraine headaches without the use of medications (3)

The scientific information out there suggests that food sensitivity testing could be used as an in vitro diagnostic test to understand how your immune system is reacting to food antigens and that following an elimination diet of those triggered foods could help in some cases manage the symptoms related to migraines and IBS.

Here we reported relative scientific literature that you could examine before take your next step. It must be taken into consideration that the food and intolerance tests are only used as preliminary screening to help you understand how your immune system is reacting to food antigens. This is the first step toward your journey to find a better version of yourself, and we are here to guide you through.

Here at Allergy Test Australia, we provide products to test blood allergy and intolerances using a simple home test kit. Our comprehensive Allergy+Intolerance test can provide you with a map of your immune system (Allergy TypeI IgE and TypeIII IgG), including IgE mediated allergy and not IgE mediated allergy (IgG4 asymptomatic).

This will be your first step into your journey, and we are here to help you through. So what are you waiting for? If you have any further questions, don’t hesitate to contact our customer service team for more information.
