Low TSH and fatigue

I just found out that my TSH is low but free T3 and T4 are normal. The fatigue has been getting worse and also the heart palpitations are increasing. (This could be part of a herx due to pulsing Mora/Cumanda with Cowden protocol.) I had been able to go to exercise class but lately I have been too exhausted. I have constipation issues and can't sit down to watch tv any time of day or I fall asleep. I don't have other symptoms of hyerthyroidism and have not lost weight. Does anyone else have low TSH? I thought that hypothyroid was more common with Lyme and that is what I was expecting. Any thoughts or advice are appreciated. I can't get into see my doctor for two weeks, so I am not sure what he will do. Thanks.

Thanks for the link Razzle. My anti-thyroid antibodies were normal but he didn't check my reverse T3. Didn't have my adrenal function tested. I am in Canada....not sure if an accurate test is available here.

Please be sure to follow up on all of this! Razzle listed a great website for learning about thyroid & adrenal issues, testing and I even found a good doctor through that site.

Although I healed from these infections - I went through a bunch of stress and ended up with Addison's, hypothyroid, and with intestinal food allergies. The back side of my thyroid was swollen, making it difficult to swallow pills, although food and liquids seemed to go down fine. Having only the back side of the thyroid swell is a rare thing according to my doctor, and we didn't know that's what it was until I was put up to 1/2 of a grain of Amour Thyroid twice a day. That's when the swelling went down and I could swallow pills easily again - almost like magic! LOL!

Because my TSH and T3 were all within the 'normal ranges' -although they were at the low end, I had ENT's telling me that I had things like esophageal pockets and other odd things that needed surgery! I refused their services though, fortunately! Otherwise I would have only lined their pockets with money and would have still had that darned lump in my throat and not be able to swallow pills!

With the treatment for adrenal issues (adrenal support and supplementing with DHEA) and doing an extensive elimination diet - I'm feeling much, much better!!

Moral of the story? Be sure all of your possible thyroid and adrenal issues are checked out thoroughly!

I had to seek out a MD that uses nothing but natural medicines to help me with my thyroid & adrenal issues. The practitioner that I was using for healing from the tick-borne infections, while good for that, didn't know enough and wasn't allow to run any tests due to stupid state laws here that allow only MD's to run tests.

Swinging between hyper and hypo thyroid is actually fairly common for someone who's thyroid is really struggling. I would highly encourage you to spend some time doing a bit of reading on: www.stopthethyroidmadness.com/
Tons of information on this site!!

And it only makes sense for anyone that has been sick for long to have some issues with low functioning adrenals too.
