Try not eatting any grains for just one week. I'm celiac and if I get into something I'm not supposed to, I blow right up like a thanksgiving day balloon!! And if the grains are the problem, not eatting them is the only way to stop the problem. Helps with the weight loss! Just going on a gluten free diet, I lost 15lbs in 3 months! Here is a web site with lists of things to avoid. Being celiac can also cause thyroid poblems because it activates several autoimmune problems. http://www.celiac.com
