First, he said that since the random cortisol test put my level at 293 at
about 3 pm (range up to about 600; I can't remember exactly), I don't have
adrenal insufficiency. I then told him I didn't think the test could mean
anything because I'm still working my way off the naturopathic supplement
for AI, but that I was satisfied to leave the subject for a few months and
if I still have symptoms then, to open the subject again. He was agreeable
to that.
About the symptoms. Susan told us in the hypoglycemia thread on Dec. 2 that
her hypoglycemia went away with a restricted carb diet, so I'm wondering if
my carboholic tendencies and not AI are to blame for this problem for me.
Jennifer told us on Nov. 23 that she experienced episodes of low bp and
dizziness on standing with being hypo, which went away with a dosage
increase, so that could be an explanation for my low bp. I've noticed just
in the past week that the lightheadness upon standing is considerably
reduced; this is at the same time that my daytime resting pulse rate has
gone up from the low 50s to the low 60s, and is a couple of weeks after a
dosage increase. I'm going with the theory that these 3 things are
connected. Also, 6 weeks ago my job changed from a sometimes stressful one
to an easier-paced one for a few months, and I can feel myself unwinding.
Last spring, I was doing 2 people's jobs for awhile for up to 11 hours a day
when everything that could go wrong did, and at the same time that I had an
arm injury, a wrist injury, a wrist brace and being hyper to deal with.
Wouldn't all that cause anyone's body to pump out more adrenaline and
possibly lead to problems?
Thanks, everyone who participated in my search for answers on this subject.
I hope the accumulated info has been useful to others as well.
Attention Vancouver, Canada people: I have found a doctor here who is
willing to prescribe T3 to hypo people who feel they need it. In fact, he
said he couldn't think of a reason not to. He thinks that only some hypo
people have a conversion problem, and that may be true. A doctor colleague
of his is hypo and apparently does well on T4 only. He also prescribes
desiccated thyroid (the equivalent of Armour in Canada) to those who prefer
it. If anyone wants this doctor's name, please contact me directly.
Here's a question for the big kids. He said that if someone is taking
synthetic T3, they don't need T4. Really? T4 converts to T3, but most people
here prefer both. ?? Wouldn't there be a problem of energy lows with no T4
backup because T3 is fast-acting?
Thanks again,
Lois

I'm told that some T4 in the mix reduces the roller coast ride that straight T3
may give.

Actually, all of the thyroid hormone action can be explained solely by
T3. So, you don't NEED T4 provided there is sufficient T3 around. BUT,
the advantage of T4 is that it is a store house to even the dips on the
rollercoaster of life (I know, an even worse patenTED analogy than John's,
tough luck). T4 has the ability to both go to T3 as needed, but also to
be shunted to non-productive ways when the body DOESN'T need more T3.
This allows you to be on ONE dose rather than figuring things out from
season to season or one activity period to the next (or, in my case,
being in kindergarten, RECESS period to NAP time). Some days you just
need MORE thyroid hormone than others, but to have to adjust yourself
on the fly, it gets messy. There are many pitfalls to trying to second
guess the causes of how you feel on any given day, and there are ample
opportunities to make mistakes. Why not mimic intact thyroid function
and shoot for a T4:T3 ratio of about 12:1? Or, go by the NEJM approach
to get the intact thyroid production of about 6ug of T3 per day plus the
rest of the way there with T4? The desiccated products, btw, are all
in the ballpark of T4:T3 of 4:1, way more T3 than intact thyroid function
secretions.....(a long story if anyone needs sleep inducements....).

What days would those be? Is the amount of exercise a person gets in a day a
factor in how much hormone is needed? If I go from doing just bicycle
commuting to adding workout rides to riding all day, every day for a couple
of weeks on a cycling trip, should I anticipate needing more hormone and
possibly increase the dose while on the trip or while increasing the workout
levels?

As you know, I am not one to advocate changing dosages on a daily basis the
way Nick does. There are too many chances for misinterpreting the needs.
As you are on a desiccated product, you WILL have some T4 along for the
rides. Don't obsess, don't micromanage....

OK, but doing a self-supported cycling tour means your body has to put out a
*lot* more than usual. I eat a lot more when I'm cycling all day; I don't
call that obsessing or micromanaging, but necessary fun. If I don't eat and
eat, my legs won't pedal. Doesn't it follow that if I'm riding distances and
hills every day for 2 weeks, my body would need a lot more hormone, too?
This is not just hypothetical for me because depending on my health and the
group situation, I may be going on such a trip in February. I also think
it's possible that part of why my condition went downhill last summer was
due to my sudden increase in cycling uphills without a dosage increase.
Thanks again,
Lois

Open mouth, insert foot.
When Ted was 3 years old, he put his shoes on by himself for the first time.
His mother noticed that the left shoe was on the right foot. She said, "Son,
your shoes are on the wrong feet." He looked up at her with a not-yet-hypo
raised eyebrow and said, "Don't kid me, Mom. I KNOW they're my feet."
--------------
Ted's friend Mahatma Ghandi walked barefoot everywhere, to the point that
his feet became quite thick and hard. He was also quite a spiritual person.
Even when he was not on a hunger strike, he did not eat much and became
quite thin and frail. Furthermore, due to his diet, he wound up with very
bad breath. Therefore, he came to be known as a...
"Super calloused fragile mystic plagued with halitosis."
>What about a time released t3?
>Monica
I heard of someone who went from T4 to Armour to sustained release T3.
She described the T4 as a foggy day, the Armour as wonderfully clear after that,
and then when she was on just sustained T3 she realised the world was still a
bit misty on the Armour.
It can suit some people, I've never tried it.
At some stage I may try replacing some of my Armour dose with an amount of T3
equivalent to the T3 in the Armour to see what happens. My gut feeling is that I
am not converting appreciably and that I need the large dose of Armour because I
need that much T3. This is why I get a roller coaster if I don't spread te
Armour.
My Doc has said if I want to experiment like that he will support me.
Until you have done it, I wouldn't hazard a guess. My gut feeling is that
the difference is minimal as long as you do have T4 available. One possible
suggestion: Do some serious exercising the day before/day of the testing
to simulate the worst case NEED for more hormone.... Or talk to the
wild ones that do fudge their dosing every day (just don't tell me about
it, cuz I'll have to restate my reservations about doing it).

Ted, the teacher, was giving a lesson on the circulation of the blood. Trying
to make the matter clearer, he said, "Now, kids, if I stood on my head the
blood, as you know, would run into it, and I should turn red in the face."
"Yes," the kids said.
"Then why is it that while I am standing upright in the ordinary position the
blood doesn't run into my feet?"
A little fellow shouted, "Cause yer feet ain't empty."

Could you please turn your head while I ask....Hey, wild ones, do you want
to go up against Ted on this one? Come on, it's fun. I'm interested in your

opinion to play with.
Thanks while cheering for both sides,

Speaking of using your head....
Police in Radnor, Pennsylvania, interrogated a suspect by placing a
metal colander on his head and connecting it with wires to a photocopy
machine. The message "He's lying" was placed in the copier, and police
pressed the copy button each time they thought the suspect wasn't telling
the truth. Believing the "lie detector" was working, the suspect confessed.
A man in Virginia went into a drug store, pulled a gun, announced a
robbery, and pulled a Hefty-bag face mask over his head--and realized that
he'd forgotten to cut eye holes in the mask.
A man in Johannesburg, South Africa, shot his 49-year-old friend in
the face, seriously wounding him, while the two practiced shooting beer cans
off each other's head.
A company trying to continue its five-year perfect safety record
showed its workers a film aimed at encouraging the use of safety goggles on
the job. According to Industrial Machinery News, the film's depiction of
gory industrial accidents was so graphic that twenty-five workers suffered
minor injuries in their rush to leave the screening room. Thirteen others
fainted, and one man required seven stitches after he cut his head falling
off a chair while watching the film.

He is probably talking about me :-)
I am on a stupidly high dose of Armour and should be hyper by all normal rules.
I don't know why I need such a high dose, I imagine that I either have tissue
resistance or am not converting at all and am only using the T3 in the Armour.
Bear this in mind when comparing yourself with me.
What I am doing is with the full agreement and approval of my doctor and I
understand that he is doing something similar himself.
I take 4 grains of Armour on waking and another 2 at 10.30 to 11.00 provided I
feel ready for it. Symptoms that will prevent me taking more are shaking hands
of 'feeling' my heart beating. These are the ways hyper presents itself for me.
I then take more during the day if I feel myself slump and this does depend on
physical activity. My normal maximum is another 2 grains, typically 1 at 3.00 at
another at 5.00 to 6.00. If I have to function late into the evening on a long
drive or working then another at 9.00 but this is VERY rare, 2 or 3 times a year
typically.
The amount I need does depend on both physical and mental activity. On a lazy
day I can get away with the 6 grains and on a busy active day I need the 8.
The symptoms that I feel if I slump are brain fog and sometimes crashing
fatigue. These will pass within half an hour of taking another grain.
The more I think about it the more I think I am not converting and that these
peaks and dips are because I am only using the T3 component of the Armour.
Next time I go to Dr D-P for a check up I will probably ask to try cutting the
Armour to 2 grains a day and taking T3 for the booster doses. He has already
said he will support me if I want to try this.
All the usual warnings about don't try this without your Doctors approval etc
apply.

Do you ever have labs done? It would be interesting to see the
numbers.

This is interesting timing. I went to an alternative health centre this
afternoon, mostly to deal with an old arm injury, but also to see if the
treatment there could help my thyroid. When I asked the doctor (whose
philosophy is to combine the best of both Eastern and Western medicine) how
acupuncture could help a malfunctioning thyroid that needs more hormone, he
said it can rebalance the yang energy, or something like that, and that hypo
people have an imbalance of this sort. Laugh if you want, but when I went
for one acupuncture treatment somewhere else last summer for my arm and got
a full body treatment, I suddenly needed much less sleep. I wonder if your
tissue resistance or conversion problem could really be a yang problem.
This doctor wants to treat one thing at a time and we're starting with the
arm injury, so I'll let you know how it goes when we get to the thyroid.

Everyone reacts differently, of course, but (ET, you might want to look away
now) based on what you (Nick) wrote, I'd like to talk to my doctor about
taking more if I get that crashing fatigue. I always carry extra food with
me when I'm cycling and I try to eat before I'm hungry and crash, so it
makes sense to me to be prepared the same way with my happy pills.

Will you let us know how it goes? I'm interested in hearing about it, and
I'll bet Ted is, too. ;-) You might want to try acupuncture first,
though....
Thanks,
Lois
PS to Ted: I haven't disregarded any of your advice, but when I go on a
group cycling-camping trip, I *need* my body to be capable of putting out
what some people consider insane amounts of energy. If I can't keep
pedalling, my trip will be ruined, so I have to look at all options.
>

No
My Doc is happy to treat by symptoms using temperatures, pulse rate, and 'feel
good factor' as parts of the puzzle.
I am private without insurance so would have to pay for the tests myself and
there just seems no point. My NHS Doc did not believe I had a problem in the
first place, if the TSH is below 5.5 the NHS around here does not believe you
can have a thyroid problem.
The numbers would be interesting but I'm not interested enough to pay for them!
I know how I feel now and my activity/ability levels compared with 18 months
ago.

Here are more thoughts:
Other than dosage questions, why are over 90% of the problems with meds that
we read about here to do with synthetics and not natural thyroid?
Could it be that the piggy bits in desiccated thyroid (e.g. Armour) other
than T4 and T3 actually serve a purpose that hasn't been discovered yet?
As I suggested in another post, perhaps Nick's conversion problem is
something that is correctable. Rather than continuing to drive a car with
lowered gas mileage due to mechanical problems, why not get the mechanical
problems fixed and improve the gas mileage that way instead of continuing to
pump extra fuel into the car? (Hey, you started the car analogies.)
Lois
Thanks, John. I was thinking more in terms of an extra 1/2 pill, but what
hyper problems are you talking about that need attention immediately, other
than hunger? I did a 2-day mountain biking trip last spring when I was hyper
(just before I realized it), and the only problem I remember was not having
packed enough food to satisfy my ravenous appetite. Fortunately, we crossed
paths with civilization at around noon, and I was able to get more to eat.
What should I watch out for?

I'd rather go for Armour plus T3 synthetic if I'm going to do anything
different.

You might try to take a pill and dissolve it in water ( say about 16
ounces ). Now, just a thought, but if you do that you should be able to
drink a portion of that water and take an eansy, tiny bit at a time to help
without too much time or hassle ( just remember to keep THAT bottle separate
from your regular water ).
If you are taking T4 your body should already be making what you need by
conversion ( unless THAT is your problem ).
Just a couple of thoughts to help keep you around. Not too many people
will go head to head with Ted. Personally, I rather agree with him too much
to be able to even consider how to approach being on a decidedly different
side of a problem.

Perhaps because over 90% of the people taking thyroid replacement are
taking synthetics? I don't actually know this to be the case, I'm just
speculating.

I've never been on T4 only, so I don't know about that, but I do know how
demanding cycling-camping trips are on the body. And because we're
self-sufficient as a group, we need to carry such things as a first aid kit,
spare tire tubes, a tool kit, etc., so it makes sense to me to carry a
thyroid first aid kit, too, if I learn beforehand how to use it.

I recently got my TSH measured at 4.72. The first GP I saw, Olga, insisted I was
fine as this was just within the top limit for normal. Olga treated me
contemptuously and I shall always remember her as Olga the ogre for her lack of
humanity. But this time I was armed with this NG's info, lots of information from
the web and, importantly, Ridha Arem's book. I saw a second doctor who, God bless
her, put me on 50mcg synthetic T4 (Oroxine). That was just 9 days ago.
My question is - how long should I wait to go on T3?? I've been on T4 for 9 days
now and, as expected, my fatigue hasn't lifted. I don't think it will until I go
on T3. Arem's approach is to establish the correct T4 dosage based on a TSH of
under 2 and, if hypothyroidic symptoms persist, trade off some T4 with T3. But
it'll take ages to find my correct T4 dosage and I want to improve as soon as I
can. I can't wait for my Cytomel! (Tertroxin actually, as I'm in Australia).
What shall I do? Should I start taking a few mcg of T3 every day immediately and
gradually build up to 10 or 15 mcg? Will this affect my TSH level and make it
difficult to find my optimal T4 dosage? I want to climb out of my hole I'm in as
fast as I can... Any thoughts appreciated.
Usuff.

Doesn't the argument for synthetic hormones vs. natural remind you of the
push to use infant milk formula rather than breast milk for babies? It's now
accepted in the developed world that the natural product is far superior,
but I read a few years ago that infant formula companies were pushing their
product in developing countries, trying to convince parents there that a
formula was better than what mothers' bodies produce. Since being hypo is
less common than having babies, I don't know if natural will ever be
generally recognized as better for thyroid hormone replacement.

That sounds like a reasonable argument, but it still could be that there
simply are more problems with synthetics. I haven't been keeping track of
problems with desiccated thyroid, but I can remember only 2 complaints about
it in the past year or so, but numerous ones about synthetic drugs. There
are a couple of websites where patients who might still be on desiccated
thyroid are advocated to switch to the synthetic hormones. That sounds like
brainwashing to me, and it scares me. Does anyone here have any natural vs.
synthetic stories to share?
: 3) You know your body the best, but you canNOT be objective about it.

We can't be objective, but when you listen to a doctor spout the rubbish
about desiccated thyroid not being as good because it isn't standardized, or
say that only T4 is necessary, or that the patient is fine because the TSH
is "in range" even though the symptoms are still there, do you consider such
a doctor objective? They are simply parroting what they've read, which isn't
based on reality.

I wonder about this. I've made mistakes by self-medicating and I'm being
careful not to go there again, but what would you say to those who are very
informed about their hypo condition, perhaps more than their doctors, and
can't find a doctor to prescribe T3 or Armour, but can buy it on the Web?
This is not my situation, but if it were, I would be tempted to, as you say,
be foolish.

sometimes wondered what we would do if someone developed acute appendicitis.

This is not an exact analogy as pig thyroid is not the same as human
thyroid - infants are not fed pig milk and it is known that cow's milk is
very different than human milk. I had more severe up and down symptoms
on Armour than I ever had on synthetic T4 or T3 even though these still
fail to make me feel well. I hoped Armour would be the magical key to
wellness but so far there is none since my thyroid was messed up.

Obeying the dr. at times can harm you even more than doctoring yourself.
The reason is they rigidly go by the book or other patients' experiences,
and believe a dose must be stuck to for 3 mos. to prove its effect,
whereas you live with your symptoms every day and know how different doses
feel and can tell if you are in distress from feeling either hypo or
hyper.
In efforts to lower my TSH, I was overdosed more than once and was in
danger. To continue on the excessive dose for 3 months as they wanted was
impossible. Even with the best endocrinologist in the city now, the
president of the department at the main hospital, he is only guessing and
I am his guinea pig. His latest guess (add .5 - T3 at the end of the day
to prevent fatigue) is no different than my guesses for years (take less
when heartbeat is racing, divide the doses, etc.) His guess made me hyper
too, and from fatigue I went to insomnia and constant tremors. There is no
final solution yet for me. I often wonder what percentage of thyroid
replacement patients ever find a dose that works for them most of the
time.
Fortunately (?) calcitonin is also produced by the parathyroids.....
Other than that.... It is released when calcium levels are too high, to serve
as a check on parathyroid hormone and vitamin D. Obviously it is used in
treatment of osteoporosis, so it seems to me to be worthy of keeping going
rather than dismissing, too.
I wonder how the calcitonin situation bears on the conflicting studies
that seem to show (or not) bone loss associated with thyroid replacement.

Usuff,
I know how hard it is to wait but Alyson and John are right to advise
you to do so. Adding T3 will definitely affect your TSH level and
make it difficult to find your optimal T4 dosage. And it is possible
that you will not need T3 ; T4/T3 therapy is much more difficult to
manage than T4-only therapy so you wouldn't want to start taking it
unless you are sure that you are not responding adequately to T4
alone. It may not "take ages" to find your correct T4 dosage since
your baseline TSH of 4.72 is not that high. Give it the 6-8 weeks
necessary to stabilize the levels and then get lab tests (including
Free T4 and Free T3). Remember not to take the T4 in the morning
until after the blood is drawn for the test. Then, if your TSH is
between 0.5 and 2.0, try to wait at least the three to four months
that Dr. Arem recommends before considering adding T3 (and lowering
the T4).
Rochelle

I don't want to suggest that your TSH will definitely stabilize
between 0.5 and 2.0 in just 6-8 weeks. It could take longer, you
might need an adjustment in the dose.

I haven't read any post on this newsgroup either from anyone who
"sings the praises of T4 alone" and T4 alone certainly did not work
for me. (I'm still not feeling well, just increased my dose of T4 two
weeks ago, but there is some slight improvement. I am also taking 10
mcg. Cytomel.)
If you go to http://thyroid.about.com and then go to the bulletin
boards (thyroid forum) and post your question about whether anyone
there feels well on T4 alone (or look it up in the archives), you'll
see from the responses that some people do.
I think that you may see a cardiovascular response to the T4 before
you see a response by some other systems of the body. Different
systems seem to respond at different times. For example, the effects
on skin and hair may take months to abate. The central nervous
system? I don't know. This is just speculation but perhaps it might
take a few weeks or a couple of months; antidepressants can take that
long to work and thyroid hormone and antidepressants both act on the
beta-adrenergic receptor, if I remember correctly.
I wish I had something more comforting to say than "wait." I know how
hard it is to feel that your life is on hold; I feel the same way
right now. But by starting the T4 you are making progress. Even if
you eventually end up adding the T3, you are on your way to
establishing your T4 dose now and that is important as it will guide
you later in determining how much T4 you'll need with the T3.

The philosophy of 6 week dose changes on T4 is that it takes that long for the
levels to stabilise in the blood stream.
T3 has a much shorter life in the body and would probably stabilise in levels in
1 week, certainly 2.
There is a complication if you are on less than a full replacement dose in that
the addition of T3 will lower TSH which in turn reduces your own thyroids
hormone production and hence this changes the T4 levels that then take longer to
stabilise.
Oh, no. Can't you change that, Nick? You're messing up my plans. :-(
My situation is that I started on a too-low dose of desiccated thyroid at
the end of Oct. and have been gradually increasing the dose with my
internist. I'm on 30 mg/day and am hoping to increase it again after my next
appt on Wed., which will be 3 wks after the previous increase. The internist
thinks it isn't necessary to wait 6 wks to increase the dosage and I like
that way of thinking. I'm also working with a time line--I have a cycling
vacation coming up in Feb., and I'm the group leader. With a current free T4
of 11.9 in a range of 11-22 (this dr. prefers to measure fT4 instead of the
TSH), I have a ways to go, and how am I going to get there if we don't
increase the dose every 2-3 wks? But by doing this, am I messing up the T4
level? I realize the original question was about adding T3 to synthetic T4,
so perhaps my concern doesn't relate to your explanation, but I'm confused.
In my situation, do the advantages of increasing the dose every 3 wks
outweigh the disadvantages, or vice versa?
Thanks,
Lois
>
>In my situation, do the advantages of increasing the dose every 3 wks
>outweigh the disadvantages, or vice versa?
I'd go with it if your doctor is willing but get him to keep an eye on the free
T3 as well due to the mix you are taking.
I was talking about full stability of blood numbers and you don't need to get
full stability to know that you are under dosed.
My Doc sent me up a grain at a time at weekly intervals telling me to monitor
temperatures and pulse rate shooting for a maximum resting rate of 80 (from a
starting rate of 60).
I took a rest at 3 grains for longer than a week as my body needed time to get
used to this and started the increase again when the brain fog came back.
The thing with the T4/T3 mix is that if you feel you are over (my hyper
sensations are shaking hands and 'feeling' my heart beating in my chest) then
these wear off after a couple of hours from a slight overdose of the sort you
will get if you ramp up too quickly. This is because the T3 component tips you
over the edge first and that wears off quickly.
If your Doc supports it go with the increase but watch that resting pulse.
Good luck
I probably don't need to worry about the T3 yet as I'm not near where I want
to be, but when I get closer to the target, I'll check it. (Because I'm "in
range," I don't think it's covered by my medical insurance, but it isn't
really expensive.)

for you? Did you wait until the symptoms came back before increasing the
dosage again? Were the one-week intervals when the dosage was too low for
the symptoms to disappear?

There's a difference between being hyper with high T3/T4 and low TSH levels,

watch for it.

Yes, this 'compensation' is a common effect as your own thyroid reduces output
as a result of the changed TSH from the applied hormone.

Many times

Not really on the initial increases but I did on the later ones.

You would probably see it in a week.

Do that, if it happens back off for a few days and then try again at the dose
that caused the hyper. You will probably find that you can tolerate it then.

This is interesting. I wasn't expecting this, and it sounds strange to me.
Why does the thyroid gland reduce output to compensate if the body still
isn't getting enough thyroid hormone? If it keeps doing this, do you have to
go a little hyper briefly and then wait for the latest output reduction to
reach the right level of thyroid hormones, gland-produced and supplemental
in combination? You said it's a common effect--does that mean it happens to
some but not all of us?
Perhaps the thyroid gland is like the government. They provide welfare
relief for those who have run out of other income, but when people on
welfare manage to earn a little money, the government reduces its output to
'compensate,' even though that bit of money isn't enough to raise their
standard of living to an acceptable level and it isn't raised at all when
the govt reduces its output. Another hmmm.
Thanks again,

A compensatory reduction in hormone production by the thyroid gland
doesn't make sense to me as an explanation for the adaptation to a dosage
increase. If TSH falls or T increases, there must be a net gain: Thyroid
levels are higher than they were before the dosage increase.
I suspect that the "feeling better, feeling worse" cycle is partly a
result of the fact that higher levels of thyroid hormones increase the
requirement for thyroid hormones. That is, the more you have, the more you
need. As dosage goes up, metabolic rate, activity level, and clearance of
T4 and T3 all increase. When you reach your optimum dosage the effect
should taper off.
Another factor that contributes to the FBFW cycle is that, in
hypothyroidism, the thyroid shifts production from T4 to T3, and various
peripheral adaptations occur that make the best possible use of the
thyroid's limited output. When replacement therapy is begun and TSH falls,
these adaptations are reversed. The loss of adaptation to hypothyroidism
might explain why people often feel worse when they start treatment,
especially treatment with T4 alone. TSH falls, but T3 may also fall, and
peripheral T4->T3 conversion isn't up to speed yet (that, too is reduced
in hypothyroidism, in order to allow the brain to have first crack at the
limited supplies of T4.)

Jennifer,
This is just what it says in Chapter 9 Part 3 of the De Groot Online
Thyroid Disease Manager. I think it just happened to me. All of a
sudden, after starting to feel like I was at the threshold of getting
better, I felt the symptomatically like I did last July before my
Synthroid was raised. My worst symptom is this feeling of being slowly
asphyxiated. So I just raised the Synthroid again. I hope that what I
am now on (100 mcg. Synthroid and 10 mcg. Cytomel) is my optimum dose.
Rochelle
Do any of your explanations include a drop in fT4?

If your thyroid 'set point' (ie the level that the hypothalamus/pituitarary is
trying to stabilise things at) is wrong then each time you have a dose increase
your body reduces it's own production to stabilise it back to where you were
before.
The time this stops happening is when you get to full replacement dose, your TSH
will end up around zero but your FT4 will be correct.
Your TSH will be low because your body 'thinks' it is hyper do to it's own
version of 'correct' being hypo.
I hope I've made myself clear.
Jennifer, Nick, and Lois,
From what I (who am not a doctor) can understand of Chapter 9 Part 3 of
the De Groot Online Thyroid Disease Manager, if the patient's thyroxine
clearance increases as his/her metabolism increases and, therefore, "a
dose of levothyroxine that is adequate when the patient is metabolizing
thyroxine more slowly may be inadequate when the patient is euthyroid,"
this should be reflected in the thyroid tests: the TSH should go up, the
Free T4 should go down. This is why they recommend repeating the TSH
test (although they elsewhere advocate monitoring both the TSH and
estimates of free T4) "after the patient has been euthyroid for
approximately 6 months."
But if there is a compensatory reduction in thyroid hormone production
by the thyroid gland after a dose increase because the pituitary is
stimulating it less (in order to maintain the thyroid level at the same
level, as Nick says), then the TSH should, of course, be lower. The
Free T4? Would it be about the same until the thyroid gland is
completely suppressed and at that point start rising to a therapeutic
level?
Of course, one could also feel worse after initially feeling better
after a dose increase simply because the thyroid gland is failing more
due to the autoimmune process and this should be reflected in the tests
as a higher TSH and a lower Free T4.
And, of course, the preceeding discussion presupposes the reliability of
the thyroid tests, something I am not sure we should do.

Sorry about the repetition. I was not trying to allude to a "Seinfeld"
