tsh ft3 question

Answered on August 19, 2014
Created March 09, 2012 at 1:18 PM

now i know tsh "doesn't matter" however my ft3 is too low and i have an rt3 problem AND my tsh is creeping up. i have AWFUL fibro. i can't strengthen bc my muscles all feel tight and just bad. i assume these are correlated? would taking cytomel bring my tsh back down? right now it's a 4. thanks!

fwiw paleo made this rt3/ft3 ratio worse. now eating white rice.

Hi Holly, One thing I forgot to mention is that when you go to get your thyroid tested, take your pills to the lab with you, get your blood drawn, then take the dose. You want to see how much hormone is left after your body is "done" with it not how much is there right after you take your pill. Also don't be put off by synthetic vs bio-identical thyroid medicine. Many people do well on synthetics (I am one) and the bio-identical, whether from a compounder or Natur-thryoid/Armour, is nearly useless.

I think you need to do better than that. Did you actually read it? There is barely a reference and it's not explained or quantified, and I don't have a password to read his sources. This is on reference from 1981. Endocrinology moves slow, but it is not 1981. Today thyroid drs are having success reducing carbs, insulin, trigs, etc. I will keep an open mind and eagerly await something specific.

Carbohydrate restriction has been proven to increase RT3 and lower free T3. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1568435/pdf/envhper00465-0066.pdf

When you say test the adrenals, what are you looking at? My doc checked cortisol via blood tests. I've heard saliva is better but I dunno. I ended up taking a "bio-identical" cortisol for a few months, with pure T3 also. When these dispensaries say "bio-indentical" what does that mean to you? I've heard different explanations.

That's not a valid comparison. I'm talking about Paleo-friendly drs that have experience and know what they are doing, not pill pushers.

Well, all the good drs I know that are treating high cholesterol are putting patients on statins. So much for good drs and what they all know.

Hi Holly,

I am impressed your doc has tested your RT3, so few do. There is a lot of preliminary info out there relating fibro to low thyroid function (and low serotonin levels too). You said your Free T3 is low but not how low. Typical lab ranges are 2.3 to 4.2, The mid-range on this is about 3.25. If you are less than 3.25 then that is your minimum goal to work toward.

Armour certainly isn't a fix-all (despite how much alternative docs push it)and in fact, since it was reformulated and re-released, we have has a LOT of people not be able to get much benefit from it, even people who had done well on it before it went off the market 2 years ago. It is about 3-4 parts T4 to 1 part T3 and if your T3 is low then Cytomel (or its cheaper generic) sounds warranted.

BTW, have you had your anti-TPO and anti-thyroglobulin tested to make sure you don't have an autoimmune thyroid condition. I hope your doc aggressively treats the low T3. Zinc and Selenium and tyrosine are all major thyroid "foods" so you might add some of these and try some tryptophan 1-4 caps when you wake, at mid-morning, mid-afternoon and at bedtime as these will help the fibro symptoms as well.

Have you had your saliva cortisol tested. If you are low cortisol then the thyroid Rxs don't work well and tend to provoke adverse symptoms rather than helping much. Typically I test the adrenals 1st, work on supporting them if needed then direct the person toward a doc who will be aggressive with thyroid Rxs, meaning he or she will increase the prescription dose every 3 weeks if no or little progress is made and treat symptoms, not reference ranges on a piece of paper.

I suggest going online and putting together a checklist of low thyroid symptoms from various sites and checking all that apply (and even rating them from 1-10 in terms of severity). This will help both you and the doc evaluate progress.

Also I suggest doing basal temps (see any site referencing Broda Barnes for instructions).

Good luck and be pushy about getting the care you so obviously need.

I don't believe claims that "Paleo" or LC make rT3 worse. rT3 is raised (and T3 lowered) by calorie restriction, or possibly bad thyroid meds. This is the so-called "starvation response."

My thyroid/hormone doc treats fibro and high rT3. This office will not use any of the big phrama thyroid T4 or T4/3T3 mix. They use so-called "bio-identical" T3 and it worked for me (not for fibro but for hypothyroid).

All the good drs I know that are treating rT3 problems put patients on higher protein and low carb.
