I have long advocated for celiac disease testing for people who have IBS symptoms. IBS is a set of symptoms that can be cause by a wide array of conditions including celiac disease, food allergies, hormone dysregulation, infections, bacteriological imbalances, and others. I just wanted to add yet another published, peer-reviewed study in a very highly respected journal that demonstrated that patients diagnosed with IBS on the basis of their symptoms often have undiagnosed celiac disease. Here is the study: http://www.wjgnet.com/1007-9327/15/5321.asp or find it on pubmed at http://www.ncbi.nlm.nih.gov/pubmed/19908341
CONCLUSION: CD (celiac disease) is common in patients with presumed IBS. Routine screening for CD in patients with symptoms of IBS is recommended. For a collection of published studies on the testable and treatable causes of IBS, see the Innate Health Foundation's website research page at http://www.InnateHealthFoundation.org/5_c.htm.Rather than just living with IBS, I always recommend those who suffer from these symptoms to see a doctor who has been successful at finding and treating the underlying causes of IBS. Best of health to you all.
