Even though my blood tests show that I’m on the correct dose of Levothyroxine since having a hemi-thyroidectomy, I cannot shift the pounds, even though I am eating very few calories every day. (Everything that I do eat throughout the day is nutritious, small portions, and I have no junk food or “empty calories “).
Has anyone else experienced this problem whilst taking Levothyroxine?
Any advice would be greatly appreciated. Many thanks.
Who said they were the perfect levels? Your doctor? A doctor wouldn't know perfection if it got up and punched him in the eye. Anyway, it's not about blood test levels, it's about how you feel, whether your symptoms are gone. So if you still can't lose weight, you're probably not on the right dose.
Do you have the actual numbers: results and ranges? If so, post them here and let's have a look. 
Thankyou for replying to me. I will get the actual figures from my blood test from my gp and post them. It’s very kind of you to offer to have a look at them for me. Apart from the weight issue, I’m feeling well.
Don't ask your doctor, he'd probably rather you didn't know! Especially as he's pronounced them 'perfect'! Ask the receptionist for a print-out - it's your legal right to have one, but they will never just give it to you.
Welcome!
Levothyroxine is not a weight loss drug but inability to lose weight can be a sign of undermedication.
Since your dose is 50mcg, a starter dose, it is almost certain that you need an increase.
You should have been retested after 6 weeks and your dose adjusted then
if you were on the correct dose your symptoms would be resolved.
Do you have any symptoms on this list? Tick them off and show your GP
Symptoms are an important part of diagnoses.

Medics have poor knowledge of thyroid disease and of analysing lab results.....that's why over 135,000 concerned patients have arrived here
i guess TSH is being used to monitor your medication which once medication is iniated is an unreliable marker
thyroidpatients.ca/2021/07/...
FT3 and FT4 are the important labs and your results should sit roughly 75% through the reference range
Essential nutrients ( listed below) must be optimal.
A full thyroid test....TSH, FT4, FT3, vit D, vit B12, folate, ferritin and thyroid antibodies TPO and Tg
Many of us test privately ...

Very low calorie intake can impair T4 to T3 conversion and if T3 is low ill health follows
Thyroid weight gain is not like that resulting from overeating/ poor diet it relates to metabolism.
If T3 is low metabolism slows down and weight gain occurs.
Oxygen saturation may be low because one role of thyroid hormones is to promote oxygen delivery to tissues. So, if you have low thyroid hormone levels (hypothyroidism), your tissues may have low oxygen levels causing fatigue.
You need to have a full thyroid test to evaluate your thyroid hormone status, ask your GP or test privately.
You are legally entitled to request copies of test results from your surgery. Suggest you do this and post them.
Who told you your "results are perfect"?
Post any results you receive and members will help.
With correct medication your health should improve
Good luck
Thankyou so much for your detailed reply and for the links. My GP was very happy with the results of all my blood tests and although I told her I couldn’t lose weight, she wouldn’t give me an increased prescription for LEVO. I am not overweight, but would like to just lose 3 or 4lbs. It feels very awkward to me to tell my gp that she is wrong, I can’t imagine that will go down well🥺
I will post my results for you to have a look at next week.
I has come to this for most of us here so don't be too concerned about standing up to your GP, who probably knows far less about your condition than you could imagine! They might well learn a great deal from you and treat others better in the future 😏
Honestly once you've questioned them once and found them lacking it becomes a bit of a mission 🤗
When you know how little time doctors spend on learning about the thyroid in Med school you will no longer be so concerned about asking awkward questions. Thyroid conditions are notoriously poorly treated, not just here but worldwide.
Like many of us you probably grew up with the idea that doctors know best and it can be hard and actually quite scary when you realise that isnt always the case.
However if you learn as much as you can about your condition you grow in confidence and knowledge and become an expert patient 😁
Very very unlikely your levels are adequate
Please add actual results
50mcg is only standard STARTER dose
Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
For full Thyroid evaluation you need TSH, FT4 and FT3 tested
Also both TPO and TG thyroid antibodies tested at least once
Very important to test vitamin D, folate, ferritin and B12 at least once year minimum
About 90% of primary hypothyroidism is autoimmune thyroid disease, usually diagnosed by high thyroid antibodies
Autoimmune thyroid disease with goitre is Hashimoto’s
Autoimmune thyroid disease without goitre is Ord’s thyroiditis.
Both are autoimmune and generally called Hashimoto’s.
Significant minority of Hashimoto’s patients only have high TG antibodies (thyroglobulin)
Low vitamin levels are extremely common when hypothyroid, especially with autoimmune thyroid disease
20% of autoimmune thyroid patients never have high thyroid antibodies and ultrasound scan of thyroid can get diagnosis
In U.K. medics hardly ever refer to autoimmune thyroid disease as Hashimoto’s (or Ord’s thyroiditis)

guidelines on dose levothyroxine by weight
Even if we frequently start on only 50mcg, 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
pathlabs.rlbuht.nhs.uk/tft_...
Guiding Treatment with Thyroxine:
In the majority of patients 50-100 μg thyroxine can be used as the starting dose. Alterations in dose are achieved by using 25-50 μg increments and adequacy of the new dose can be confirmed by repeat measurement of TSH after 2-3 months.
The majority of patients will be clinically euthyroid with a ‘normal’ TSH and having thyroxine replacement in the range 75-150 μg/day (1.6ug/Kg on average).
The recommended approach is to titrate thyroxine therapy against the TSH concentration whilst assessing clinical well-being. The target is a serum TSH within the reference range.
……The primary target of thyroxine replacement therapy is to make the patient feel well and to achieve a serum TSH that is within the reference range. The corresponding FT4 will be within or slightly above its reference range.
The minimum period to achieve stable concentrations after a change in dose of thyroxine is two months and thyroid function tests should not normally be requested before this period has elapsed.
TSH should be under 2 as an absolute maximum when on levothyroxine

Graph showing median TSH in healthy population is 1-1.5

Comprehensive list of references for needing LOW TSH on levothyroxine
healthunlocked.com/thyroidu....
onlinelibrary.wiley.com/doi...
If symptoms of hypothyroidism persist despite normalisation of TSH, the dose of levothyroxine can be titrated further to place the TSH in the lower part of the reference range or even slightly below (i.e., TSH: 0.1–2.0 mU/L), but avoiding TSH < 0.1 mU/L. Use of alternate day dosing of different levothyroxine strengths may be needed to achieve this (e.g., 100 mcg for 4 days; 125 mcg for 3 days weekly).
Thankyou so much for all that information! And for the links too. So kind of you to take the time to reply. After I had the left side of my thyroid removed , all my blood tests afterwards kept showing a slightly lower than range thyroid function. Before the op there was no problem with my levels. So I didn’t think I was Autoimmune?
My last bloodtest was three weeks ago at 8.30am and I had taken my Levothyroxine just 6 hours before.
So what were results
Ft4 would be false high as last dose only 6 hours before test
Get full thyroid including antibodies and vitamin testing done
as 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
As Greygoose so succintly put it, there is no such thing as a perfect blood test when on Levo. What your doctor actually means is your TSH is somewhere in the range and that is good enough. Have they even tested your FT4/FT3 levels? Just testing TSH is pointless.
Also 50mcg is just the starter dose and unlikely to be enough. Far too many of us were started on Levothyroxine, tested after a few weeks and the doctor announced hurrah, your TSH is now in range and we were "parked" on 50mcg. It happened to me as well.
If you are experiencing symptoms like weight gain then its likely you need an increase to 75mcg.
Yes, I think I do need 75mcg but my gp says I don’t. I have asked her for this and she refused , so where do I go from here?
Once you have results from a full thyroid panel and we can see where you are with your free T3 & 4 we'll be able to advise, I find it rather helps to say you have received advice and guidance from Thyroid UK and also mention the NICE guidelines 😏
Thankyou, I Will ask for my results and post them here during the coming week. I would very much appreciate your opinions. That’s good advice to mention Thyroid UK when having discussions with my GP.
Can I ask please , What do the NICE guidelines say in relation to this? Or maybe there is a link you can send me if it’s easier?
As Eeyore says try quoting or printing off NICE guidelines or try a different GP. I've found some are more flexible than others.
Note also that TSH levels vary during the day. That's why it's recommended that testing is done by 9am. You can't compare a test done at (say) 4pm with one done at 9am. If your original test was in the afternoon you may not have been diagnosed with an underactive thyroid.
Unfortunately doctors and nurses and receptionists don't know about timing of tests and will assure you that it doesn't matter - it does!
Doctors and some pharmacists also insist Levo brands don't matter and they are all the same, hence why many patients end up with different brands each time they get a prescription 🤦♀️
You are so right Sparklingsunshine. I've recently been in hospital. I was told they had Teva, but I never saw any. Accord was dished out, probably because that was what they had on the trolley.
I have always been prescribed with the Accord brand …. is this an ok brand or are there better ones please?
Accord is pretty good, its very well tolerated and widely available. Doctors will have you believe all Levo is the same, but although the active ingredient is the same, its the fillers that change.
I always get Accord as a named brand. Some hypo patients can chop and change brands with no ill effects, others need to stick to a specific one.
I didnt get on with Mercury, it contains Acacia powder and made me itch. Many members dont get on with Teva brand, it contains mannitol. Yet if you are lactose free Teva can be very good. There are no good or bad brands, its just whether they suit you or not.
Oh I see now, thankyou for explaining this.
Recently diagnosed with under active thyroid at start of jan. I have now asked for copy of blood test results.
3 months since my 1st Thyroid blood tests, had another set of tests done and not sure where to go
Does taking Levo at night not work for some people?
I need help! I had 1/2 thyroid removed & was told I had graves disease. I've still been very ill, but blood work is normal so they say Im ok
I have recently had a thyroid blood test that came back with a borderline result and have been advised to have another test in three months
