Zach’s Treatment Success with Cytomel


Zach points out that most of the posts about thyroid treatment issues at metabolism.com are from women. That makes sense because autoimmune thyroid disease is approximately 10 times more common in women than men. But man or woman, thyroid hormone treatment is still the same and his success with Cytomel is something worth noting.

Hi everyone. From what I can gather, most posters here are women, well I’m a guy with similar problems. I thought my story might be useful so that men don’t think it’s a women only problem. I gained a hypothyroid diagnosis at the age of 25 due to Hashimodo’s. There was no direct cause, it runs heavily in my family. For a year, or two, maybe even three (it’s hard to tell due to widespread symptoms), I was feeling nervous, bad memory, attention problems, sleep problems, low appetite, and easily fatigued from a normal 8 hour work day. I assumed my lifestyle choices were causing these symptoms so didn’t go to the doctor for years.

Finally when I was diagnosed I was put on levothyroxine. The very first day I took it I felt IMMENSLY better. However, months down the road the symptoms gradually built up again. Every time my dose was raised, I would feel better for about 2 days, but the symptoms would gradually return. My endo decided to drop my T4 dosage and put me on a combo T4/T3 (T4 was dropped by 50 mcg and one quarter of the drop was added in as T3, so 12.5 mcg of T3). This is the first day I’ve tried it, and instantly the morning of starting on T4/T3 my body aches have almost disappeared and I am feeling much less sleepy at my desk during work.

Michelle Gets a Boost from T3 (Cytomel)


Michelle shares her success story with T3. Michelle’s story demonstrates how combination therapy with T4 and T3 can be clinically superior to T4 (Synthroid, Levothyroxine) alone. In her story she mentions Wilson’s syndrome which I personally think is a “made up” diagnosis to help Dr. Wilson’s retirement fund but I do think her experience is fairly typical of a lot of people with hypothyroidism who eventually discover they need T3 added to conventional treatment with T4 to achieve best results.

OMG! Maybe I’m not crazy after all!
I’m 47 in December and can’t remember the last time I felt good or even okay. Same thing – doctors repeating same tests, thinking I’m exaggerating, sent to Psychiatrist…Over the past 6 years or so, major stress, low immune (sick all the time), worsening depression, borderline diabetes, high blood pressure, peri-menopause. Got to the point that I’m sooo exhausted. Don’t want to do anything. Lab diagnosis finally showed up hypothyroidism so doctor put me on Synthroid – I was so happy that I cried. Devastation set in after 6 months as this was not the miracle I thought it would be.

Started taking my temperature 3 to 4 x a day as suggested to me by a naturopath I had seen but couldn’t afford to keep going to. Again, measurements taken 3 x daily for a week averaged to 97.0. Talked to doctor about Wilson’s Temperature Syndrome; she did not believe in it and sent me for more blood tests which came back normal.

FINALLY (after 20 years at same doctor’s office) was lucky enough to be accepted under the care of a physician who hadn’t heard of WTS but had heard about the T4 not converting into the T3 (you all know the fault in the system)… so right then and there wrote me a prescription for Cytomel and told me to stop the synthroid. As the WTS website recommends sustained T3, I’m taking half the dose every 12 hours.

I started today and feel like a kid on Christmas Eve a million times over! I am so hopeful that this can get to the root of so many ailments. So many that I feel that I’m not even living my life, that I’m just here putting in everything I have just to get through the day.

With the lack of memory and concentration I have right now, I hope I remember to come back to this site and update you all!

Suzi’s Amazing Blood Pressure Response to Cytomel (t3)


Suzi has hypothyroidism and high blood pressure. She sends the following story describing how t3 treatment appeared to help normalize her blood pressure. This is the first time I have come across this effect and thought it would be helpful to share her story on the main blog. Does anyone else have a similar (or contradictory) experience?

Hi Dr. Pepper,

I was diagnosed hypothyroid 2 years ago and given levothyroxine. On diagnosis I had lots of symptoms and my BP was 175/115 despite my whole family having low BP. After some months on T4 I did feel an improvement in a lot of ways and my BP got better. Then after a year, things started going wrong, as if my body didn’t like T4.

I tried reducing my dose of T4 back down to 75µg but went hypo. But each time I increased above 75µg my BP increased again, then on 112µg it became a serious problem, especially the diastolic. I still had fatigue, constipation, red eyes, swollen legs and so on.

About 3 weeks ago I started on 10µg T3 and reduced my T4 from 112 to 75µg and pretty much immediately felt clearer headed and more energy, the constipation went etc….. My BP has gone down by an average of 20, which I know because I check it regularly myself. I’m doing a 24-hour BP monitor this week too, because my doctor put me on Amlopidine 6 weeks ago after being shocked by the monitor results from then while on 112µg T4 (only took Amlopidine for 2 weeks after terrible side-effects incl. overwhelming fatigue and massively swollen legs).

So, it looks as though my body goes weird on T4 tablets when the dose is above 75µg, but if I stuck to that dose I’d be really hypothyroid. The T3 has changed my life completely!!

Now I’m wondering what the ideal balance T4 / T3 tablets would be? Is that possible to say or does it depend on each individual body and genetics? My typical BP now is around 120/ 95; it goes down after eating, and gets worse when I’m hungry or tired. The T3 reduced my BP so much more than the Amlopidine did, and on T3 I feel great whereas on Amlopidine I felt half dead. I’d like to get my BP back to before I got hypo, so that’d be 110/70.

All I need to do now is find my ideal dose of T4 and T3, could you possibly advise me on that? If I started 20µg T3 instead of 10µg, would you advise a reduction in T4 from 75µg? ( I’ll be doing a TSH, fT3 and fT4 test in about 5 weeks’ time, maybe I should wait till then?).

Thank you so much!

What You can Learn from Sarah’s Struggle With Hypothyroidism


Every so often I like to bring attention to someone who has struggled to get properly treated for hypothyroidism. Not everyone shares the same dilemma regarding treatment of hypothyroidism because T4 by itself may be sufficient in many instances. But for those who continue to experience symptoms of hypothyroidism despite T4 treatment, adding T3 can be a life changing experience.

Here is Sarah’s story:

I was diagnosed with hypothyroidism in my early twenties and Synthroid did not help. I did not know at the time that many of my symptoms were due to hypothyroidism. After changing to my long time physician, I told her of my original diagnosis some years back. She did only the TSH and told me I was no longer hypothyroid! So for some 15 years after being in her care and continuing to feel crummy, then for the last 8 steadily gaining weight and feeling worse, I was not on any medication. I begged her for Cytomel several years back and was denied…she said she didn’t treat with that. When I finally was deemed hypo by her, she put me on the smallest dose of levothyroxine. It did not help. I finally went to see a shrink and he put me on 25 mcg of Cytomel. For the first time in my post pubescent life, I feel like living. My dose was upped to 50, and I felt even better but my thyroid levels were off, so we are now working on that and I am back to 25 mcg per day. If you can’t get Cytomel from your regular physician, you might get a psychiatrist to prescribe it. It changed my life and I finally feel alive. I’ve since switched primary physician because she wouldn’t listen to me, and she didn’t like that I was on Cytomel. I don’t know what it is about this medication that regular physicians don’t like and make them refuse to treat with it, especially when so many can benefit from it. I’ve lost only 12 lbs since being on it, but I gained nearly 35 unnecessarily while not being properly treated and was told to eat less and exercise more…I only ate about 1500 calories a day and walked my dog 2 miles each day, so I don’t feel it had anything to do with my diet!

What is My Correct Thyroid Dose?


Lots of members at metabolism.com with hypothyroidism ask what is their correct thyroid hormone dosage. For those who are still confused I am posting the latest Q and A addressing this issue.

Member ecchho received radioactive iodine for hyperthyroidism (over-active thyroid) and as commonly happens, developed hypothyroidism (under-active thyroid). Despite t4 levels which appear to be normal symptoms persist, so ecchho inquires about ways of dealing with this common problem.

Here is the Q and A regarding ecchho’s post:

Hi Dr. Pepper:

I had Graves disease at 23 and then had RAI at 28 and have been on synthroid for 18 years. I did try ARmour once, but I found it had too much t3 (I think the pig’s ratio of t4 to t3 is much more potent than humans) and I actually had a real hard time regulating. I don’t have a thyroid anymore, and I take 225 synthroid. i still suffer a bit with impossible weight loss (despite running, dieting, etc) and some depression that feels quite hormonal at times. My dr. brought up adding t3 last visit and tested me, and then said, oh, you don’t need any xtra t3, you seem to be converting fine.
what are the levels that the t3 should be, and is this free t3 or t3? thanks.

My reply to Ecchho’s post:

Your question regarding the correct level for thyroid functions, is frequently raised on this website. I would respond to your question with this question, ” What is the correct shoe size?” Obviously, the answer is, whatever shoe size fits best. Similarly with thyroid function, everyone has a different “comfort zone” where their body functions best. That is their “correct” thyroid hormone level. You also refer to a t4 to t3 ratio for pigs versus humans. These ratio’s are averages of several hundred individuals (human or pig)and do not apply to any particular individual. Some people function better at a t3 to t4 ratio which is higher than the average. As pointed out in my article,https://www.metabolism.com/2009/11/07/breakthrough-discovery-thyroid-hormone-therapy-part-2/ , there is recent evidence that due to genetic differences, a percentage of the population does not convert t4 to t3 efficiently and therefore are likely to require t3 supplementation when treated for hypothyroidism.

Rather than spend the money for genetic testing to discover whether the genes for conversion of t4 to t3 are abnormal, some doctors recommend simply adding an appropriate dose of t3 to the standard t4 (levothyoxine)treatment and following the patient for improvement in clinical symptoms. You might want to consider discussing this approach with your doctor.

Wondering if t4 (Synthroid) Treatment of Hypothyroidism is the Answer


Prosanta asks metabolism.com if her thyroid blood test results indicate that treatment with t4 is required. I suspect that she is also wondering if other forms of treatment might be better (Armour Thyroid for example).

Here is what Prosanta writes:

Iamsuffering from Diabetes type2.recently on routine Blood test—
FT3(ECLIA) 2.33pg/ml
FT4 1.07ng/ml
TSH 9.32microIU/ml
AntiThyroid Peroxidase 37.02IU/ml
Do I need to take only Levothyroxine

In response to her question I offer my thoughts on whether someone beginning with thyroid hormone replacement therapy should start with t4.

Hi Prosanta

You know I can’t recommend medical therapy in this forum. I can make some general comments, however.

There is debate among endocrinologists about what level of TSH indicates a clinical degree of thyroid deficiency, but there is no doubt that a TSH of 9 is abnormally high. Since elevated TSH almost always indicates that the pituitary gland is releasing excessive TSH in response to thyroid hormone deficiency, unless there is a pituitary tumor (exceedingly rare), replacement therapy with thyroid hormone is indicated.

Thyroid hormone replacement therapy in the U.S. usually consists of taking a pure t4 product such as Synthroid or levothyroxine (generic t4). On this website you will notice extensive posting about treating hypothyroidism with alternative forms of thyroid hormone replacement, particularly desiccated thyroid products such as Armour Thyroid. An appropriate concern in a situation like yours is whether to take t4 only or to use desiccated thyroid or t4 plus t3 therapy.

If you are like most people in this country being treated with t4, you will wonder why someone might need alternative forms of thyroid hormone replacement. In the past year or so researchers have discovered that a portion of the population lacks the ability to normally metabolize t4 into the highly biologically active t3. This means that affected individuals may continue to experience symptoms of thyroid hormone deficiency when treated with conventional t4 therapy [https://www.metabolism.com/2009/11/07/breakthrough-discovery-thyroid-hormone-therapy-part-2/ ]. How does a person know if they won’t respond to t4? The simpliest approach is to try t4 and see how you feel. Then you and your doctor can decide whether you are a t4 responder or not.

You may be aware that Armour Thyroid and similar products are in very short supply in the U.S. Even if some advocates of desiccated thyroid therapy for hypothyroidism argue that only desiccated thyroid can result in a full return to normal, in my opinion the present shortage makes t4 therapy the clear initial choice. If symptoms of hypothyroidism persist even after a full course of t4 has been tried, then you may be forced to join the ranks of those struggling with the pharma industry to get desiccated thyroid products.

Please discuss these ideas with your own physician.
