She may have Celiac Disease. Celiac Disease is the inability to digest, wheat, rye, barley and oats. Gluten is in practically everything, while I would suggest to eliminate it, it will be difficult. University of Chicago specializes in Celiac Disease, testing, diagnosis, etc. It often goes undiagnosed, even by GI specialists, however you will have to demand the for the test, which is through a blood test AND colonoscopy to get a true diagnosis. Does she have headaches, eczema or other skin rashes? Has she lost any weight? If you google Celiac Disease, you will find tons of info. Gluten Free Expo is Sept. 12 and 13 in Oak Brook, www.glutenfreeexpo.com (I believe) is the website. It is there once a year (for future reference) but there will specialists, chefs there.
