I agree with June. My dd was diagnosed with Tourett's. She was always very emotional and broke down often. In addition, she often had diareah and lots of bloating. Her stomach was hurting all the time. My pediatric doctor was just telling us that this is the way her body works. Finally, during her kindergarten, she started to have horrible stomach aches after every breakfast and she vomited often. She had some other emotional issues. I noticed that she was on the smaller side in her class. The same doctor just told me that if she would weigh any less, then it would be time to worry. I got tired of listening to this doctor and took my dd to allergy specialist. Results were showing for her to be non-allergic to any food. Then I started to experiment with vitamins and diet. I read this forum, Bonnie Grimaldi's website and other sources. I excluded all tyramine foods, colors, prservatives, msg and gave her extra magnesium among trying other additional suppliments. To make our story short - we are on gluten-free diet for a few months now. Her stomach works normal. She does not break down emotionally anymore. Her tics are gone. We are staying on gluten-free strict diet but started to relax more with tyramine and other foods. Occasionally, she gets some candy (full of colors and othe chemicals) at school. Sometimes, we forget about vitamins. Then I usually see some slight tics returning but nothing like before. Personally, I think that gluten and tics maybe related but there is no double-blinded studies to be sure, so I would recommend to reaseach and try gluten-free, tyramin-free, chemical-free diet for a few months at least to see if it helps.
