Cristina, since Italy has a higher-than-normal incidence of Celiac Disease, have you been tested for that recently?

It sounds like you might have MG; many people with MG have problems with Gluten (found in wheat, barley, and rye), even if they test negative for CD. A gluten-free diet could alleviate some of your problems with fibromyalgia and Hashimoto's, at the very least.

You may want to ask your doctor to run a blood test for Celiac Disease - just make sure that you are still eating gluten when you have the test done. Even if you test negative for CD, you might want to try a GF diet - many people with MG find that they feel better when gluten is eliminated from their diet.

Italy is at the forefront of Celiac Disease research, as well as GF awareness, so it should be relatively easy to switch to a GF diet. Our family went GF in 2008 when our youngest child was diagnosed with CD - I felt so much better after just 24 hours on it that I've had no problem staying on it ever since. (I was diagnosed with MG in 2010)

I hope that you are able to find answers soon -
