Just because you don’t have celiac disease, doesn’t mean you are free of problems with gluten

I find two approaches to be effective in combating the symptoms of IBS:

• Identification and elimination of food triggers.

• Correction of any underling imbalance in the ecosystem in the gut.

It is possible that any food can trigger IBS symptoms. In my experience, wheat is the No. 1 offender. Sometimes wheat sensitivity is caused by sensitivity to a protein found in wheat (as well as oats, rye, and barley) known as gluten.

In conventional medicine, gluten sensitivity is a recognized condition that is known as celiac disease. This can be tested for using blood tests and biopsies of the lining of the small intestine. If the tests come back positive, celiac disease is diagnosed. If they come back negative, it is often assumed that not only is there no celiac disease, but also there’s no sensitivity to wheat or gluten. But is this really so?

I have seen over the years many patients who have turned up negative test results for celiac disease, but who nonetheless have IBS symptoms that seem to have a very clear relationship with wheat consumption. Last year, a 4-year-old girl came to my practice whose parents told me she got diarrhea when she ate wheat, but had no diarrhea if she didn’t eat it. The test of celiac disease was negative, and her dietitian (with the support of her gastroenterologist) enthusiastically advocated a diet for this child that was full of grain-based foods, including wheat.

What are we to make of individuals who don’t appear to have celiac disease but nonetheless appear to react adversely to wheat? It’s possible that individuals may react to wheat in a way or through mechanisms that are not necessarily related to full-blown celiac disease.

This concept was put forward recently in a paper that appeared in the American Journal of Gastroenterology. Doctors based at McMaster University in Hamilton, Canada, and the Mayo Clinic, Minnesota, United States, put forward the idea that gluten can induce symptoms similar to FBD “even in the absence of fully developed celiac disease.”

In short, just because someone doesn’t have celiac disease, doesn’t mean the bowel symptoms are not due to gluten.

One simple but often effective way of identifying food sensitivities is to eliminate foods to see if it helps. One problem here is that some individuals are sensitive to a range of foods, and if all of them are not removed, symptoms may persist even though problem foods have been eliminated. To be on the safe side, I tend to recommend that when they take out wheat, they take out other gluten-containing grains and dairy products.

In my experience, the overwhelming majority of IBS sufferers improve dramatically on this regime. Foods can be added back into the diet (about one every two days) to see which foods cause a return of the IBS symptoms.
