Feeling cold and low body temp

11 Replies

Hi I’m just wondering if feeling cold( especially feet) is a sign of being under medicated. My

Temp first thing was 34.4 just retaken and 35.2. I’ve had quite erratic thyroid results lately. I stopped taking T3 about a month ago (self sourced) as I felt no different on it. Plus I hadn’t told my GP So thought I’d refrain till I’d had a few tests and go back to basics d sad o to speak. I have got low t3. First test (medicheck) was 3 and second 2.69. My last ferritin came back at 21 but doc said this was fine because of other iron results. I’m at a loss. I’m going to do monitor my health thyroid panel on Monday morning and due docs ones probably towards end of August. X

Ferritin is too low

drhedberg.com/ferritin-hypo...

This is interesting because I have noticed that many patients with Hashimoto’s disease and hypothyroidism, start to feel worse when their ferritin drops below 80 and usually there is hair loss when it drops below 50.

Eating iron rich foods like liver or liver pate once a week plus other red meat, pumpkin seeds and dark chocolate, plus daily orange juice or other vitamin C rich drink can help improve iron absorption

Vitamins frequently crash right right down when T3 is stopped

Recommend getting FULL thyroid and vitamin testing 6-8 weeks after stopping T3

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

Private tests are available as NHS currently rarely tests Ft3 or thyroid antibodies or all relevant vitamins

Think you are on 100mcg levothyroxine?

Do you always get same brand of levothyroxine?

Which brand?

Many people find Levothyroxine brands are not interchangeable.

Once you find a brand that suits you, best to make sure to only get that one at each prescription.

Watch out for brand change when dose is increased or at repeat prescription.

Many patients do NOT get on well with Teva brand of Levothyroxine. Teva contains mannitol as a filler, which seems to be possible cause of problems.

Teva and Aristo are the only lactose free tablets

healthunlocked.com/thyroidu...

Teva poll

healthunlocked.com/thyroidu...

academic.oup.com/jcem/artic...

Physicians should: 1) alert patients that preparations may be switched at the pharmacy; 2) encourage patients to ask to remain on the same preparation at every pharmacy refill; and 3) make sure patients understand the need to have their TSH retested and the potential for dosing readjusted every time their LT4 preparation is switched (18).

Levothyroxine is an extremely fussy hormone and should always be taken on an empty stomach and then nothing apart from water for at least an hour after

Many people take Levothyroxine soon after waking, but it may be more convenient and perhaps more effective taken at bedtime

verywellhealth.com/best-tim...

No other medication or supplements at same as Levothyroxine, leave at least 2 hour gap.

Some like iron, calcium, magnesium, HRT, omeprazole or vitamin D should be four hours away

(Time gap doesn't apply to Vitamin D mouth spray)

I’m on 75mcg teva thyroxine...after my last t4 of 23.7 (9-22) I was asked to lower it. I feel it’s too low. I was going to add 15mcg to it but just want to do the monitor my health test on Monday morning first. Regards my ferritin when I brought this upto doc she said all the other iron tests were ok, so could it be low because my tablet dose is too low x

Looking at previous posts your dose is changing too much and too quickly

April 20th - test on 50mcg levothyroxine

healthunlocked.com/thyroidu...

Mid June

on 100mcg levothyroxine and 12.5mcg T3 last test

That’s vast change in very short space of time

healthunlocked.com/thyroidu...

After April 20th you were going to increase levothyroxine to 75mcg

Suggest you stick on 75mcg and retest after minimum of 8 weeks

You could test vitamin levels now, or test after 8 weeks too

Yes that’s my plan 👍

SlowDragonAdministrator in reply toTinacros

Increases must be slow and steady. It takes 2-3 months minimum for each dose increase in levothyroxine to settle

Thanks. Can I just ask do you know what the best OTC meds are to increase ferritin. I’ve bought spatone sachets x

humanbean or SeasideSusie may pop along

But eating liver or liver pate once a week always gives good results

My last ferritin came back at 21 but doc said this was fine because of other iron results.

This was discussed in previous post here healthunlocked.com/thyroidu...

I would never suggest anyone takes an iron supplement on the strength of low ferritin alone.
