Hey guys..

I know I've asked this question in my previous post but, I've just had my results and gp is saying thyroid is dangerously low?? And i should up my meds?

Will this be dangerous for my baby?

I'm on 25mcg of Levo

6.25mcg x 2 daily at seperate doses.

I also have low cortisol but didn't do anything about it as I found out I was pregnant.

TSH 1.73 (0.27- 4.2)

T4 7.1 (10.5- 24.5)

Ferritin 44. (13-150)

Heamaglobin 108 (120-150)

Haemtocrit 0.33 (0.36- .046)

Vit D 120

I am extremely exhausted all the time and want to sleep all day 😏

And advice /suggestions will be greatly appreciated x

It's important to have FT4 values . If low your OBG should be increasing your dose if your on T4 already and if not yet dosing with T4 you should for sure start . It's very important for your unborn baby develop well and beyond . It's also very important for you as the mother to be . It helps keep BP down and from you to develop Toxemia . And can help one from miscarriage .

I hope you take it up with your OBG and sort it out soon .

Your GP needs to test B12 and folate too, both very important for a baby's development

See GP to discuss trying to increase your Levothyroxine

Your TSH is not responding to low FT4

You should be seen by endocrinologist who is a thyroid specialist

Have you had thyroid antibodies tested?

You also need FT3, FT4 and TSH tested together. Thyroid test should be as early as possible in morning

I am self medicating with t3 .. (gp is unaware)

I'm on 25mcg of Levo. I feel toxic if I up any more Levo..

B12 is over range .. I get shots done myself every 3 months.

I have hashis too

I did the blood test early morning while fasting.

Your TSH is not responding to low FT4.

What is meant by This?

Thank tou

Well I suspected you were on T3

Almost any dose of T3 will significantly lower TSH, regardless of low FT4 is

How much T3 are you taking and is this as single dose or 2 or 3 split doses?

If you are taking T3 its ALWAYS essential to test FT3 and FT4 together

Obviously you need to do so privately. Would strongly recommend you get vitamin testing too. Extremely important to have good folate levels during pregnancy.

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and fasting. Last Levothyroxine dose should be 24 hours prior to test, (taking delayed dose immediately after blood draw). This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

If/when also on T3, make sure to take last dose 8-12 hours prior to test, even if this means adjusting time or splitting of dose day before test

Is this how you do your tests?

Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies or all vitamins

thyroiduk.org.uk/tuk/testin...

Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have special offers, Medichecks usually have offers on Thursdays, Blue Horizon its more random

Medichecks currently have an offer on until end of May - 20% off

I'm taking 6.25mcg of t3 at half 8 in the morning with 25mcg of Levo.

And then another dose of 6.25mcg t3 at 11:30pm.

(Does this sound like a good dosing time?)

I do all my blood testing as suggested above..

So you need to test TSH, FT3 and FT4 together to see what your levels are like

Plus test vitamin levels

Personally I need three doses of T3 at eight hour gaps. But everyone is different
