Low Temp (95*F) and Blood Results = Low Test/Thyroid


#1

Iv got low temp as title says.

My FT4 is 16.4
Test 6-8
Cortisol 550

From what I can tell low temp and high FT4 hints to iodine deficient / poor thryroid function as apposed to auto immune disease.

Havnt got the full spectrum back till next week but that's what I got from old blood test 2 weeks ago from GP. Unfortunately he didn't test for anything else...

Any help would be appreciated

Why is this a new thread that does not have the context of your earlier posts?

Always need lab ranges.

Please read the thyroid basics sticky.

  • note issues re stress, infections, accidents etc
  • what is your history of using iodized salt and/or vitamins that list iodine

How often do you check body temps?

  • temperature when you first wake up
  • temperature in the mid-afternoon

Can that thermometer get to 98.6 with someone else?

What other symptoms of hypothyroidism do you have?

  • dry skin
  • brittle nails
  • feel cold easily
  • low T
  • fatigue and brain fog [also symptoms of low T]
  • enlarged or lumpy/asymmetric thyroid gland

fT3 controls body temperatures, not fT4
need fT3 lab data
if fT3 is mid range or higher, your low body temps suggest elevated rT3 which implies adrenal and adrenal fatigue issues, see that sticky.

I thought it would be easier to start fresh.

    I have read thoroughly,no stress/infections but severe head injury when I was younger. They picked up on thryroid issue but GP never found anything on follow ups (wasn’t testing the right things)
  • what is your history of using iodized salt and/or vitamins that list iodine
    No salt in diet (everything I eat is mostly grown naturally) but I do take orange triad multi that contains 250mcg idodine

How often do you check body temps?

  • temperature when you first wake up
    Yes 4 days in a row average 35*C
  • temperature in the mid-afternoon
    Same average as morning 35.5*C

Can that thermometer get to 98.6 with someone else?
Yes

What other symptoms of hypothyroidism do you have?

  • dry skin
    Yes
  • brittle nails
    No
  • feel cold easily
    Yes
  • low T
    Yes
  • fatigue and brain fog [also symptoms of low T]
    Yes (main symptom)
  • enlarged or lumpy/asymmetric thyroid gland
    Not that I know of.

if fT3 is mid range or higher, your low body temps suggest elevated rT3 which implies adrenal and adrenal fatigue issues, see that sticky.

Other notes
-train intense 5-6 days per week (not a massive calorie intake but gain fat easy, macros are balanced)

  • have done 1Ph cycle but had symptoms long before that

I’m thinking it’s either
Head injury related
Iodine
Or overtraining (but I’m very keen to train and strength is increasing which isn’t a sign of overtraining? )

You may have effects of head injury and thyroid/iodine issues.

"take orange triad multi that contains 250mcg "

  • how many years have you used that?

You are so far from 37C in the afternoon, your temperatures are very low.

A head injury might have left damage visible on a MRI, however, seeing that would not change the outcome.

How old are you?
Prolactin tested?

Try to get TSH, fT3 tested.

On and off for 2 years. (Probably 12 months full use)

Yes worryingly so, almost hyperthermia haha! I do feel icy cold to touch most of the time… Surprised I’m not blue!

I did have an MRI in my follow up to head injury and nothing was mentioned bar (thyroid was dodgy and they wondered if I was recovering from something or if jt was related (two years on GP never found anything but as iv found out from requesting bloods only tested for TSH and t4… Which iv posted above.

How old are you?
22
Prolactin tested?
Results due back from endorcrine clinic 3rd dec

Try to get TSH, fT3 tested.

As above has been done by endocrine (luckily she specialises in thryroid problems)
