You've got abdominal pains, bloating, fatigue and foggy thinking. You feel worse after eating wheat or other foods with gluten, and better when you avoid them… Experts urge people who suspect they have problems with gluten to be tested for celiac disease before going gluten-free on their own. Otherwise, with no gluten to react to, their blood tests will show false negatives. "This is the single biggest problem I see, and I see it every day in practice," says Joseph Murray, a celiac expert at the Mayo Clinic in Rochester, Minn.
