Have You Been Diagnosed With Irritable Bowel Syndrome? You Could Be Having Immune Reactions To Food!

January 31, 2011 · Filed Under Irritable Bowel Syndrome 

I was misdiagnosed with irritable bowel syndrome for 5 years prior to my diagnosis with celiac disease. Unfortunately, I have talked to many other people who have been misdiagnosed with this syndrome as well. Some individuals really had a gluten intolerance (celiac disease, dermatitis herpetiformis, or non-celiac gluten intolerance), some had food allergies (IgA, IgG, and IgE antibody mediated), and others appeared to find relief on a paleolithic diet.

The group on a paleolithic diet may have found relief due to a lectin intolerance, a gluten intolerance, or a food allergy since the foods they react to may have been eliminated with this type of diet. Other people, like myself, eat a paleolithic diet, but still have to remove a few additional foods from my diet due to food allergies.

Elimination of certain foods may bring relief, but other factors should be considered. The bowel may be in a state of dysbiosis if reactions to foods have been occurring for along time. Testing for parasites, bacterial and fungal infections may also be necessary. As well, your physician (medical doctor or naturopathic doctor) may recommend probiotics to help restore a natural flora balance in the intestinal environment. This can help to prevent future infections and may lesson the leaky gut effect.

I believe it is beneficial for patients with irritable bowel syndrome to be tested for a gluten intolerance since studies show that there is an association (celiac disease, dermatitis herpetiformis, or non-celiac gluten intolerance). As well, testing for food allergies (IgA, IgG, and IgE mediated), a lectin intolerance, and further testing for the presence of infections may help.

My book, “Gluten Toxicity”, discusses 12 different gluten intolerance tests, some considerations with allergy testing, and how the paleolithic diet may be helpful.

Future Studies

In a future study, I would like to see a large group of patients with irritable bowel syndrome tested for infections, gluten intolerance (celiac disease, dermatitis herpetiformis, and non-celiac gluten intolerance), a lectin intolerance, and food allergies (IgA, IgG, and IgE antibody mediated). The results may help to improve the lives of many who are suffering with irritable bowel syndrome.
