just a quick one at the mo-

I have been treated for many years, and following my early breast cancer in 2021, the subsequent aromatose inhibitor (to reduce the oestrogen levels in my body to help prevent recurrance) has played havoc with my BP, cholesterol and thyroid meds.

I saw an Endo, who eventually decided to try adding a small amount of T3 -reducing my Levo from 125mcg to 100 and adding 5mcg T3. Finally got the results of latest test -I did ask for a full panel, but only got these three-

29 Nov 2023

Serum TSH level

0.16 mIU/L

0.35 - 4.94

Abnormal

Serum free T3 level

4.10 pmol/L

2.63 - 5.70

Normal

Serum free T4 level

16.40 pmol/L

9.01 - 19.05

Normal

I have not yet started the T3 as I was waiting for these results. I don't feel too bad, but tingly/slightly numb fingertips, cold hands often, slight brain fog at times, and still putting on weight in spite of eating little.Lethargic too. Do I make the change to add the T3 and see what happens? All other levels are good as I had them tested recently and my last B12 shot was 6 November. I take selenium with the Thyroxine around 5 am usually but neither the morning before the test.

I am juggling Endo, cardio and Onco people and each is only interested in their 'bit' of me-I'm trying to manage all three!

With results like that I would suggest not dropping your T4 dose and just adding in a little T3 to see how you feel, adding T3 often drops fT4 levels and yours isn't that high...

TSH 0.16 mIU/L (0.35 - 4.94) -4.1%

Free T4 (fT4) 16.4 pmol/L (9.1 - 19.5) 70.2%

Free T3 (fT3) 4.1 pmol/L (2.63 - 5.7) 47.9%

T4:T3 Ratio 4.000 

If you have 5mcg tablet I'd suggest cutting into 2 and just taking 2.5mcg for the first couple of weeks 🤗

It is a shame that they don't work on whole bodies but I suppose it is just too much for them and it gets left to us!!

Thank you for the prompt response! I'll try your suggestion!

You might find 2.5mcg is enough so don't feel you need to increase if it's working for you 🤗

I take selenium with the Thyroxine around 5 am

You take both at the same time? Not a good idea. For maximum absorption levo should be taken one hour before food (two hours after), two hours away from most supplements but four hours away from some of them, like iron and magnesium.
