Puzzled hashimoto or not unsupportive GP

Notdepressed profile image

Hello all I am hypo after 2 year fight GP relented and gave me levo 50mcg, perimenaupause with GI issues high bp and now high cholesterol (GP sent me email to say it was high and website link for government site, no conversation…). Feeling continuously unwell, mood lethargy energy etc I paid for 2 x bloods 3 months apart, fasting in the morning no levo since 24 hr -pic attached. Any thoughts or insight most gratefully received feel unsupported by GP and at a loss. Have done some research and am non dairy, gluten and watch carbs have reflux and on omeprazole, thanks for reading

High cholesterol is linked to hypothyroidism *. NHS know this.

Properly treating the hypothyroidism should reduce the cholesterol.

Which of those tests is the latest one ?

mind you whichever it is , you re still clearly undermedicated and your GP should be to increasing the dose of Levothyroxine by 25mcg immediately

(Because the free T4 (thyroxine ) is under range on both, and 'optimally' treated patients on Levothyroxine should have TSH under 2 * )

We have several references for this * if you need them to show GP

Thank you for reply the bottom one is latest, will read up thank you any supporting evidence for levo increase gratefully received my GP is not supportive

OK, will look them up now , but if the latest one is 8.39 . you should get an increase with no bother.

even TSH of 3.98 is still too high for someone on Levo (unless you felt well )

So GP should increase levo by 25mcg as a result of either of these tests .

References for keeping TSH lower in ALL patients:

This one ..... from page 13 in the liothyronine (T3) guidance... sps.nhs.uk/wp-content/uploa... " NHS consultant endocrinologists may start a trial of combination levothyroxine and liothyronine in circumstances where all other treatment options have been exhausted.

1. Where symptoms of hypothyroidism persist despite optimal dosage with levothyroxine.

(TSH 0.4-1.5mU/L)

2. Where alternative causes of symptoms have been excluded, see box 1 below"


This one ..... from PULSE magazine for GP's... The article is available from ThyroidUK

If you want a copy of the article then email tukadmin@thyroidUK.org

and ask for a copy of the Dr Toft article in Pulse magazine. The quote is in answer to question 6.

Dr Toft, past president of the British Thyroid Association and leading endocrinologist, states in Pulse Magazine:

"The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range - 0.2-0.5mU/l.

In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l.

Most patients will feel well in that circumstance.

But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l.

This 'exogenous subclinical hyperthyroidism' is not dangerous as long as serum T3 is unequivocally normal – that is, serum total around T3 1.7nmol/l (reference range 1.0-2.2nmol/l)."


This Graph showing TSH in healthy population ..... web.archive.org/web/2004060... (show's most are around 1 , 4 is extremely rare in healthy people )

and a post on here discussing it: healthunlocked.com/thyroidu...


plus This one ........ found in GPonline.com 15th April 2010.


"Replacement therapy with levothyroxine should be initiated in all patients to achieve a TSH level of 0.5-2.0pmol/L." Written for GP's by "Dr Iqbal is a specialist registrar in endocrinology and Dr Krishnan is a specialist registrar in cardiology, Liverpool".

* NOTE this one also clearly states that raised cholesterol is caused by hypothyroidism *


Oh and This one .... gp-update.co.uk/files/docs/...

"The goal of treatment is to make the patient feel better and this tends to correspond with a TSH in the lower half of the reference range (0.4–2.5 mU/l).

If a patient feels perfectly well with TSH between 2.5 and 5 mU/l there is no need to adjust the dosage" .


and another one .....

ncbi.nlm.nih.gov/labs/pmc/a... "Given the complexity of pathways that govern TH action at tissue and cellular levels, it is not surprising that some patients receiving exogenous thyroid hormone replacement therapy report on-going symptoms despite optimal thyroid function tests

(e.g. normal T4 and T3 with TSH <2 mU/L in primary hypothyroidism).


just adding this so i can find it again later :

MHRA Safety update re. switching brands of Levo gov.uk/drug-safety-update/l... "If a patient reports persistent symptoms when switching between different levothyroxine tablet formulations, consider consistently prescribing a specific product known to be well tolerated by the patient. If symptoms or poor control of thyroid function persist (despite adhering to a specific product), consider prescribing levothyroxine in an oral solution formulation."

Thank you

just realised i didn't make those links work .. will do it now . hang on ;)

Presumably the top results are after being on 50mcg levothyroxine

How long on this dose

Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine

50mcg is only a STARTER dose

The aim of levothyroxine is to increase the dose slowly upwards in 25mcg steps until TSH is ALWAYS under 2

Most important results are always Ft4 and Ft3

When adequately treated Ft4 will be 60-70% through range and Ft3 at least 60% through range

See/contact GP for next increase in levothyroxine up to 75mcg per day

Essential to test vitamin D, folate, ferritin and B12 too

Have you had these tested, highly likely low

Thank you for reply, 4 years GP adamant that dose is correct and will not prescribe higher despite, symptoms continuing. no repeat bloods ever after brand change (did not know this was a thing) standard 6 month bloods requested only. I have constant reflux which is helped by omeprazole only take when it’s very bad though. Pic attached recent bloods


Hi I don't see acid reflux mentioned that often with hypothyroidism but it was definitely something that thyroid treatment improved for me. I was on daily omeprazole, also laxatives and suppositories which are no longer needed. I am still struggling with other issues but I found GI issues the first thing that thyroid treatment eliminated.

SlowDragon profile image

How long have you been on omeprazole?

Most hypothyroid patients have LOW stomach acid

Any PPI like omeprazole is to treat high stomach acid

Low stomach acid can be a common hypothyroid issue

Thousands of posts on here about low stomach acid


Web links re low stomach acid and reflux and hypothyroidism










Protect your teeth if using ACV with mother



Omeprazole will tend lower vitamin levels even further




PPI and increased risk T2 diabetes


Iron Deficiency and PPI





You must not simply stop PPI

Getting levothyroxine dose increase is first step

Being hypothyroid causes low stomach acid, increasing levothyroxine dose should help improve gut function

Testing vitamins absolutely essential

Come back with new post once you get vitamin D, folate, ferritin and B12 test results

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

HelloI’m sorry you are feeling so bad. Meno on top of thyroid issues is extremely tough- I’m suffering along side you atm.

Your results indicate Hashimoto’s as both antibodies over range and you are under medicated for thyroid. But likely they’ll only increase after 6-8 weeks by 25mcg. And you’ll have to ask for it in my experience with NHS GP blood tests will need repeating first. Problem is, they’ll only check TSH which is why so many of us end up spending money we don’t have on private thyroid sympathetic GPS and private bloods, as you’ve discovered. I’m sure The more experienced and knowledgable will be along shortly with more suggestions.

Your journey is a mirror of mine and I’m in full sympathy with you x

Thank you wishing you well I will keep fighting

High cholesterol is linked to being under medicated for thyroid

Your GP should be aware of this (rarely seem to be)


If you have an underactive thyroid (hypothyroidism), treatment may be delayed until this problem is treated. This is because having an underactive thyroid can lead to an increased cholesterol level, and treating hypothyroidism may cause your cholesterol level to decrease, without the need for statins. Statins are also more likely to cause muscle damage in people with an underactive thyroid.

Getting dose levothyroxine increased will reduce cholesterol

Guidelines on eventual dose levothyroxine likely to need is approx 1.6mcg per kilo of your weight

Dose has to usually be increased slowly upwards in 25mcg steps, retesting 6-8 weeks after each increase

guidelines on dose levothyroxine by weight

Even if we frequently don’t start on full replacement dose, most people need to increase levothyroxine dose slowly upwards in 25mcg steps (retesting 6-8 weeks after each increase) until eventually on, or near full replacement dose

NICE guidelines on full replacement dose



Consider starting levothyroxine at a dosage of 1.6 micrograms per kilogram of body weight per day (rounded to the nearest 25 micrograms) for adults under 65 with primary hypothyroidism and no history of cardiovascular disease.

Also here



Traditionally we have tended to start patients on a low dose of levothyroxine and titrate it up over a period of months. RCT evidence suggests that for the majority of patients this is not necessary and may waste resources.

For patients aged >60y or with ischaemic heart disease, start levothyroxine at 25–50μg daily and titrate up every 3 to 6 weeks as tolerated.

For ALL other patients start at full replacement dose. For most this will equate to 1.6 μg/kg/day (approximately 100μg for a 60kg woman and 125μg for a 75kg man).

If you are starting treatment for subclinical hypothyroidism, this article advises starting at a dose close to the full treatment dose on the basis that it is difficult to assess symptom response unless a therapeutic dose has been trialled.

BMJ also clear on dose required

Definitely Hashi's.

Some information about Hashi's:





Supplementing with selenium l-selenomethionine 200mcg daily is said to help reduce the antibodies, as can keeping TSH suppressed.

How long have you been on 50mcg Levo?

Retesting with GP should be 6 weeks after starting Levo, increase by 25mcg, retest 6-8 weeks later, repeat until levels are where you need them to be for you to feel well.

The aim of a Hypo patient on Levo only, generally, is for TSh to be 1 or below with FT4 and FT3 in the upper part of their reference ranges, if that is where you feel well.

If GP is reluctant to retest/increase then use the NICE guidelines which he may be ignorant of:


1.4 Follow-up and monitoring of primary hypothyroidism

Tests for follow-up and monitoring of primary hypothyroidism

1.4.1 Aim to maintain TSH levels within the reference range when treating primary hypothyroidism with levothyroxine. If symptoms persist, consider adjusting the dose of levothyroxine further to achieve optimal wellbeing, but avoid using doses that cause TSH suppression or thyrotoxicosis.

1.4.2 Be aware that the TSH level can take up to 6 months to return to the reference range for people who had a very high TSH level before starting treatment with levothyroxine or a prolonged period of untreated hypothyroidism. Take this into account when adjusting the dose of levothyroxine.


1.4.3 For adults who are taking levothyroxine for primary hypothyroidism, consider measuring TSH every 3 months until the level has stabilised (2 similar measurements within the reference range 3 months apart), and then once a year.

1.4.4 Consider measuring FT4 as well as TSH for adults who continue to have symptoms of hypothyroidism after starting levothyroxine.

Hashi's isn't treated, it's the resulting hypothyroidism that is.

Hashi's can cause gut/absorption issues so it's important to test key nutrients as these are often low or deficient:

Vit D




High cholesterol is one of the signs/symptom of hypothyroidism, avoid statins if they are offered, hypothyroidism has to be treated before considering statins:


If you have an underactive thyroid (hypothyroidism), treatment may be delayed until this problem is treated. This is because having an underactive thyroid can lead to an increased cholesterol level, and treating hypothyroidism may cause your cholesterol level to decrease, without the need for statins. Statins are also more likely to cause muscle damage in people with an underactive thyroid.

High blood pressure is another of the signs/symptoms of hypothyroidism so that may improve.

Which brand of levothyroxine are you currently taking

Many people find different brands are not interchangeable

Best to not change brand at dose increase

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 is the only brand that makes 75mcg tablet. So if avoiding Teva for 75mcg dose ask for 25mcg to add to 50mcg or just extra 50mcg tablets to cut in half

But for some people (usually if lactose intolerant, Teva is by far the best option)

Teva, or Aristo (100mcg only) are the only lactose free tablets

Most easily available (and often most easily tolerated) are Mercury Pharma or Accord

Mercury Pharma make 25mcg, 50mcg and 100mcg tablets

Accord only make 50mcg and 100mcg tablets

Accord is also boxed as Almus via Boots, and Northstar 50mcg and 100mcg via Lloyds ....but Accord doesn’t make 25mcg tablets

beware 25mcg Northstar is Teva

List of different brands available in U.K.


Posts that mention Teva


Teva poll


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.

New guidelines for GP if you find it difficult/impossible to change brands


If a patient reports persistent symptoms when switching between different levothyroxine tablet formulations, consider consistently prescribing a specific product known to be well tolerated by the patient. If symptoms or poor control of thyroid function persist (despite adhering to a specific product), consider prescribing levothyroxine in an oral solution formulation.


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


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)

If you normally take levothyroxine at bedtime/in night ...adjust timings as follows prior to blood test

If testing Monday morning, delay Saturday evening dose levothyroxine until Sunday morning. Delay Sunday evening dose levothyroxine until after blood test on Monday morning. Take Monday evening dose levothyroxine as per normal

I am on accord thank you for advice feel armoured to challenge GP again

You are clearly hypothyroid. Ask your doctor about link with hypothyroidism and high cholesterol. Mine still didn't care despite acknowledging I had a point, but you could use that as a basis for an increase.

Failing that try and change doctors or sorry, go private

The next step from here from your doctors point of view is BP tablets and Statins, both of which make thyroid hormone conversion harder. Many years ago when I was fairly ignorant I saw a very good private functional doctor (former GP with hypothyroidism) His words to me as the consultation finished were: "No matter what, don't let any doctor put you on statins, eat as much fat as you like, yes eat butter! I recommend it, it will do you no harm, our cells need fat, and you need all the energy you can get, but don't let them tell you your high cholesterol is due to your diet! Your high cholestrol is currently saving you from complete collapse."

I left thinking (I truly was ignorant) that he was overly zealous.

But he was dead right and I am very grateful for his words.

Dear Alanna012,

Your post (the comments of the private functional doctor, a former GP with hypothyroidism, especially his final sentence) was worth its weight in gold to me. Thanks so much for sharing.

To you and all the others on Thyroid UK, valued Administrators included, my heartfelt wishes for far better health,


Glad it was of help to you xx

Ps The cholesterol is often raised with Hyoo- mine as mine has been for a long time and I’m apparently at optimum dose.

Blood pressure swings up and down with Hashi flairs (I’ve had 2 significant bouts so debilitating unable to work for a period of time once 2 years ago & currently battling the tail end of flair 2) but usually when reasonably controlled T the lower end.

Re flairs: looking back, I see the pattern. Was fine last winter (a miracle) Sick the one before, ok one before that and sick the year before. I thought that was flu bug as not diagnosed then but I now know it was thyroid flair. Winter notoriously hard to control symptoms for some as body working harder to keep you warm. Some docs automatically increase dosage ready for winter months, I believe.

It’s a tricky condition and thank goodness for the help on here from the experienced. It’s got me through some difficult times


Thank you I’ve not been diagnosed hashimoto I suspect it will read up about thyroid flares are there any good sites of information, hoping you stay well

"I’ve not been diagnosed hashimoto" If the GP has ever done a TPOab (antibody) test and it was over range then you have already been diagnosed with it ....

.. they just didn't mention it , they often don't bother because it makes no difference to treatment of hypothyroidism.. or if they did mention it they didn't use the term 'hashimotos ' most GP's would only call it "Autoimmune Hypothyroidism".. but because this is the most common reason for becoming hypothyoid ., they often don't mention it at all .. and just write "hypothyroidism"

Important ...if TSH is now 8 you need to contact GP and let them know this... there is no question (even for the most unhelpful GP in the world) that a TSH of 8 is not OK once they are treating you with Levo .. they are clearly instructed to adjust Levo dose to get TSH into range

Seaside Susie’s links are really useful for explaining Hashis and there’s lots in line re Hashimoto’s Thyroiditis but likely you’ll need a thyroid scan to validate this recently after my current flair and ensuing illness. I paid for a private one and it was confirmed this way, but had really high antibodies a couple of years ago when first diagnosed by private GP. Both antibodies over range. Tbh NHS GPS are mainly not remotely interested in testing for antibodies so you’d have to go private or ask for referral to Endo.

I had one Endo who completely dismissed my high antibodies and blamed everything on my menopause and wanted to take me off Levo!! Needless to say, I didn’t go back. And that was a private referral. I then stuck with my private GP who is all over thyroid and treating the symptoms not the numbers.

To be fair to GPS they are general practice and won’t know everything about a specific condition- that’s the place for a specialist. However, it’s just about finding a doctor who’s willing to listen. Sadly, we get dismissed as menopausal or having depression/ anxiety or health anxiety rather than listening.

I’m all for trusting and listening to your body. I did and bingo- T4 over range and low T3 and an abnormal thyroid scan. All paid for privately but at least it gave me confirmation I wasn’t going mad or suffering from a panic disorder.

Keep faith in yourself. You know your own body.

It’s a battle so keep fighting 🤗

Thank you I will be making an appointment armed with all this information from replies have felt at a total loss recently but everyone’s help has really boosted me thank you

When adequately treated Ft4 will be minimum 60% through range

Likely to need several further increases over coming months
