Hi there
You will probably get more responses if yoiu post on the main thyroid disorders forum as for whatever reason that tends to be where most of the activity on this site is from those of us with autoimmune hypothyroid.
I know there are people there who have had good results going gluten free and equally there are people who have tried it and found it didn't work for them. It can be a bit of a controversial topic, some people have very strong opinions.
I personally haven't tried it but my doctor did suggest it might be worth a try. I think it's probably fair to say that a link between gluten and thyroid hasn't been proven by conventional medicine but there are a lot of practitioners who believe it can help and there seem also to be a fair few patients who have benefited by trying it, but that's not to say you will neccessarily be one of those.
I think the mantra is gluten free isn't for everyone so if you try it you have to recognise it may or may not help you. And the main thing to do first if you're not already is perhaps just to ensure you have a healthy diet and ensure you get all your nutrients, that applies whether or not you go gluten free.
High fructose corn syrup sounds like a bad thing in itself regardless of gluten content. Anything like that, sugar, fructose, etc, is just going to play havoc with your blood sugar so I think most practitioners would advise anyone who wants to eat healthily to try and avoid it as much as possible, along with processed carbs. I'm guessing that especially as you are carrying a lot of body weight and have thyroid issues that trying your best to eat as healthily as you can will be particuarly important for you.
Sorry you're having such a tough time. It's great you seem to have found a good doctor at last. Wishing you well. Hope to see you on here again.
peace and light
I stopped gluten because during my hashi's flare I began having an intolerance to it. I haven't had it in about a year. Let me tell you, this year was the sickest I have ever been with hashi's, AND I developed another autoimmune disease. I guess it can help some, but it didn't do anything for my hashi's unfortunately =(.
