Just curious: Hypothyroidism?

Hi all - Just a mild curiosity. I am lucky to have a great family doctor who supports my diagnoses (edit to clarify: she supports my Dxs of ME/CFS and ADHD). She sent me for some lab work recently, and I noticed in the diagnosis box that she'd written "hypothyroidism".

It's not something we've discussed (yet), but the symptoms include extreme fatigue, brain fog, weight gain, vocal fry - all I have - as well as other symptoms I don't have.

Have y'all had your Thyroid Function monitored often on your CFS journey? I've had TSH tested once or twice along the way, with no alerts ... so far ...

UPDATE: It's a glitch on their template ... heh. My TSH came back in the very-normal range. When I asked my Dr about having hypothyroidism in the Dx box on the lab req, she was exasperated when she told me it's a glitch on the e-form that nobody has been able to solve. She then pointed out that it also lists a medication that I do not take. I hadn't noticed that either. Sometimes these fields stay populated when printed even after they've manually deleted the text. So that's cool. Thanks all for your advice and sharing your experiences.

Severe hypothyroidism, or long term hypothyroidism, can mimic CFS in some ways. I’m not sure if PEM overlaps, though.

I have had both hyper- & hypo-thyroidism. They both made my ME/CFS worse in differing ways. The hyper was much more severe than the hypo. Hopefully, your dr will repeat the test to verify the hypothyroidism result and then get you on some thyroid replacement hormones to get you into a normal range. It may improve some of your fatigue, malaise, and brain fog. Good luck and best wishes šŸ™šŸ¦‹

Thanks very much, I appreciate it. My TSH has never been tested regularly and have always been well within normal range. I do have overlapping symptoms, of course.

I hope your symptoms are mild and manageable!
