The most common digestive symptoms of celiac disease overlap pretty substantially with the symptoms of irritable bowel syndrome -- in both cases, you can suffer from diarrhea, constipation, bloating, abdominal pain and gas.
That's why it's not surprising that people who have celiac disease can get diagnosed mistakenly with irritable bowel syndrome. In fact, studies show that up to 10% of people diagnosed with IBS actually have celiac. There's also evidence that others who carry the IBS label might actually have non-celiac gluten sensitivity instead.
I've detailed all of this in my article, Celiac Disease vs. Irritable Bowel Syndrome - Which Is It? It's a must-read for anyone who's got an IBS diagnosis or who is wondering whether their symptoms are gluten-related.
