View Full Version : thyroid levels & testing - can anyone explain them to me please?
Please note I'm not looking for medical advice, just to see whether someone can explain this to me. I had my thyroid removed 17 years ago, and my levels have always been okay. Until about 6 months ago, when I started to get a bit panicky, shaky, etc. I've just had the results back from my thyroid test and my level is 37 - the normal range is 4 and below! So, I've to increase my tablets slightly. However, will increasing my tablets not give me more thyroixine and therefore raise my levels - i.e. higher than 37, or will it lower my levels? I'm seeing the doctor tomorrow to try and understand it, but I can't work the levels thing out at all!
Thanks in advance - and again I don't want medical advice, I just can't understand the readings and levels thing!

I think taking more would lower your levels. I was diagnosed wiht hypothyroidism about a year ago. My first reading was around 37, I was started on 50mg of Levothyroxine, I've had blood tests every 3 months since and I've had to keep increasing although my levels are dropping. I'm now taking 125mg.
Good luck with the doc. Make sure you have in your head all the questions you want to ask (or write them down). My doc has told me about a website that the docs use www.patient.co.uk (http://www.patient.co.uk) which is really good and explains everything.
right, I see now - I'm honestly not being stupid, I've been on the patient.co.uk website earlier today and it was great. I was horrified at my reading, I've to up my tablets to 225mg for a while. My tablets have never been changed for years and years, and I've also not had my blood checked for a good few years, so I guess it's all catching up on me now!
Thank you - I appreciate your post, it makes sense to me now!

The two main tests carried out by your GP/endocrinologist are:
TSH = THYROID STIMULATING HORMONE
This hormone comes from the pituitary to stimulate the thyroid gland into making more hormone. TSH rises when the thyroid is struggling.
The approx. reference range for this test is 0.4 to 4.5.
Anything above 4.5 (along with symptoms) can indicate an underactive thyroid gland and would normally be treated with thyroxine to bring it down within range.
[B]FT4 = FREE T4
Thyroid hormones not bound to proteins. FT4 lowers when the thyroid is struggling.
The approx. reference range for this test is 10 to 24
A low FT4 (along with symptoms) can indicate an underactive thyroid and would normally be treated with thyroxine to bring it up into the range. Most people are at their best around the middle of the range, e.g. 17-19, some people need to be nearer the top end of the range to feel well. [Above 24 can indicate an overactive thyroid and your dose of thyroxine could be reduced.]
Your blood tests should be done annually.
Reference ranges taken from Thyroid UK website, I have been a support worker for them for many years.

TomsMom can I ask your advice please - I started on LevoThyroxine just over a week ago (50mg for now) and the main thing I have noticed is that before, I would drink say 3-4 glasses of red wine and feel fine. Now, I drink 2 and I feel like a sledgehammer has hit me the next morning. I can only imagine it's the LT? I never binge drink and I pretty much always drink lots of water before bed to avoid as much of the hangover as I can. But this is different.
I thought I must have just had a not-great wine, so on Friday we had some cava bubbly, and yet after 2-3 flutes, again yesterday had a horrendous hangover.
Now I am all for testing it a third time, but seems it's pretty clear my drinking days are over - do I need to just drink a couple of litres of water before/during drinking to help?

Thanks Poppy_f1, I do think that's what it is too, as I used to be able to drink more, but now it just isn't worth it. Probably for the best, no better excuse to get healthy!
Do you find some alcohols are easier on the head than others now that you are on LT?
Also are there any other symptoms on a day to day basis - I did notice that it's best to take the pill early and then snooze for a while, and leave it some time before eating. The first time I forgot that I got a little dizzy!
Also I am wondering if I should take my multivitamins with lunch instead, as I remember reading that iron and calcium can prevent the LT from working properly.

Hi all just a bump to ask, in addition to the above, does it do any harm to still take kelp supplements as well as the levothyroxine?

Yes, because kelp contains Iodine which is a big no-no if you're on levothyroxine. Avoid *any* supplement with iodine in it as it can cause issues. You'd have to be pretty unlucky to suffer from serious problems with your thryoid, but it can cause major problems in theory.
If you've got a good reason for wanting to continue taking a kelp supplement, then speak to your doctor but I have been specifically warned on a number of occasions that it's a no-no. :)

tbh its hard to explain, sometimes i can drink vodka and not have a hangover sometimes i can have 2 or 3 and feel like im dying the next day
wine - well i only drink rose, 2 weeks ago had a bottle of gallo and a bottle of weightwatchers wine, thought my head was gonna explode the next day, sat night past, had the same and i was fine yesterday
its pot luck for me, although one thing i have learned is that i cant mix drinks so i need to pick one drink (usually vodka) when im out and stick with that
and im your classic binge drinker or i used to be ;)

I agree with avoiding the kelp. As for when to take levothyroxine, when you first wake with plenty of water and about twenty -thirty minutes before food is optimum. (says on the instruction leaflet that comes with the drug!)

Hi guys thanks for the answers, flissh yes that's how I have been taking it, there was only one morning when I forgot...
Also for general info, I believe my TSH level had jumped from 6 (around 4 months ago), to 11 this time, hence he started me on the 50mg dose. I do think stress has affected it, so part of me wonders if I would need the LT if things calmed down, or I made a conscious lifestyle choice to change things, but I guess the thyroid is only going to need more help in time, so I might as well have a 'helper', as well as leading a calmer life if possible.
Wow Wolfsong I even mentioned to my doctor as I he was writing out my paperwork for the levothyroxine that I was taking kelp, you would think the first thing he'd say is 'well you can stop taking that now', just to be sure. As it happens, I have not taken it, it makes sense not to, but others might...
So I guess no more lovely seaweedy dishes in Yo Sushi then either?
And Poppy, sounds like I will have to experiment, sameway you have, as to what I will be able to drink from now on.
I do like a glass of red wine, but seems 2 small glasses gives me too much trouble now, and it's only been 12 days since I have taken LT.
I might reduce it to 1, with even more water than I would usually have, to be sure.
Before, I was drinking 1.5 litres of water a day (I work for a bottled water company), looks like I prob need 2 litres now to compensate for the LT.
I am guessing the reason is that the metabolism is working faster and therefore needs more water to flush things through?
Reactions once on Levothyroxine
Just wondered what everyones thoughts were - for me in 12 days this is how I have felt:
- Unable to drink as much alcohol
- Slightly 'buzzy' one or two days out of the 12
- Going to the loo 5 or 6 times before lunch has even hit, as I'm drinking more water
- Dry mouth especially in the morning, will drink even more water to help this
- Have cut out caffeine and reduced sugars inc honey, to see if this helps too

Interesting to read what you guys have been saying about not being able to drink as much on levothyroxine...I hardly ever drink anyhow, but can't say I've noticed a difference when I do...

Hi Wolfsong I will test it out again no doubt, I think what it is, is that you need to drink so much more water than even the recommended 8 glasses a day. This is just to be able to take LT as normal. Probably 12 glasses or so.
Then, if you are drinking, you might need to compensate with say another 4 glasses...
I have read on Google of some people getting less of a hangover on LT, wow, that would be great!

I would like to thank you for the link to the website. I have had an under active thyroid for 3 years now, and still cannot get to grips with it at all !!
