I found it very interesting as I have had discussions with others (yes, Mom, this is you) who have been diagnosed with the “garbage can” term of IBS and celiac testing has been negative. Perhaps a gluten free diet would be worth a try….
Just because you doesn’t have celiac disease, doesn’t mean you are free of problems with gluten

Many grains people eat contain gluten, which can cause various gastrointestinal symptoms.
On the Pulse with Dr. John Briffa
Irritable bowel syndrome (IBS), sometimes referred to as functional bowl disorder (FBD), is characterized by symptoms such as abdominal bloating and discomfort, constipation, and diarrhea. Its cause is often said to be unknown. However, 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 dietician (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.
Some people are keen to be tested for food sensitivity, though in my experience, no tests are foolproof. One reason is that the body can react to food through several mechanisms. Let’s imagine that someone has a food sensitivity as a result of an antibody reaction to that food. If the test specifically looks for this antibody, then it’s got a fair chance of picking up the problem. However, if it’s testing for something else, then it’s unlikely to identify the problem.
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.
