I was diagnosed with IBS in the early 90's as a teen. After having my 2nd child my Nurse Practitioner noticed my enlarged Thyroid. Diagnosed with Hypothyroidism and put on Synthroid at 0.50 mcg. During 4th pregnancy they ramped up my Synthroid to 0.75 mcg. After my 4th child is born they keep me at 0.75 mcg. My levels are testing close enough to normal then and now. I still had extreme fatigue, an in ability to lose weight and joint pain through out. After my last thyroid US in July of 2010 my crack pot of an Endocrinologist happens to mention that I have Hashimoto's and to keep my Dec appt. as he attempts to hang up as he was on speaker phone. I stop him by saying,"I have WHAT?!" and "Wait, what is it and will it go away?" . Obviously, it doesn't go away, he told me I could Google it and I found a new Endocrinologist. So, when I googled it I found the possible Gluten link and gave up gluten. That was Sept 2010. Six weeks later I had a bad day and went gluten crazy, I ate pizza, cereal, bagels, you name it. If it had wheat flour I was eating it. For a whole day in a half. I was stopped abruptly by pain in my stomach from bloat and the WORST hangover I ever had in my life feeling. Haven't touched the stuff since. Unless it's by accident. In which case I can tell immediately. I get worst bloat and pain in my stomach and abdomen within 10-30 min. I will never be diagnosed with Celiacs because I am not willing to do a challenge. I do not have 3 months of my life to feel miserable. I am a very happy Hashimoto's girl without Gluten.
