<<Disclaimer: Verify this information before applying it to your situation.>> I have received 31 responses to my previous post. I was seeking advice related to my celiac friend's loss of balance, blurred vision, double vision and short term memory loss. First I would like to express my appreciation for the words of encouragement and support expressed by so many. They are helpful during this difficult time. In summary, the reponses suggested hidden gluten in the diet, allergies, diabetes, MS, hypothriod, need more B12, low blood pressure, another autoimmunal disease, and Mineriar's disease. It seems that a number of people experience blurred vision from a gluten hit, but that it went away fairly rapidly as they recover. I understand the many suggestions for hidden gluten in the diet, but she did a recent blood test, and it showed her gluten free. Words can not express how much effort we put into making sure she only has the safest foods. Hand prepared from scratch in our own kitchen. She has seen a neurlogist, had an MRI, and EEG, plus a complete blood work up. We will follow up on the suggests of immunologist, and ophthamologist. Thanks again for your support and helpful suggestions.
