Hi ,I'm newly diagnosed hypothyroid, plus B12 , D3 and folic acid deficiency.My TSH initially was 5.9 and started on 50micrograms 9 weeks ago, plus Vit B12 shot and oral D3 and folate.
Had another blood test 2/52 ago TSH only . TSH reduced to 2.9 but still feeling awful. T4 not tested at any point.
Advice please on prescribing protocol

It can be a challenge to get FT4 tested on the NHS and almost impossible to get FT3 tested. This is why thousands of members in this group buy their own private tests to see whats really going on and if conversion to FT3 is adequate. Often it is the lab that veto's testing FT4 & FT3 not the GP.
See link for companies offering private blood tests & discount codes, some offer a blood draw service at an extra cost. thyroiduk.org/testing/priva...
There is also a new company offering walk in& mail order blood tests in London, Kent, Sussex & Surrey areas. Check to see if there is a blood test company near you. onedaytests.com/products/ul...
Only do private tests on a Monday or Tuesday to avoid postal delays.
GPs can be very conservative about increasing Levo dose believing that too much can cause harm, so instead they don't give us enough.
NICE guidelines suggest a dose of 1.6 x weight in kilos = approximate final dose
This isn't a precise way at all of estimating final dose but is a useful guide.
Most people feel well when their TSH is at or just below 1. Sometimes asking for an increase as a trial goes down well and gets the dose increase. You may need to go back and ask different docotrs but do keep asking and don't give up.
Usually you take a certain dose of 6-8 weeks, retest then increase until your TSH is at or just below 1.
With so many deficiencies have you been tested for coeliac disease?
Obviously with the various deficiencies you have it will take a while to feel better and you will need to continue to supplement Vit D & folate once your prescription finishes.
With B12 injections its recommended to also take a good methyl B complex which will help keep all the B vitamins in balance. Suggest you do this after your folic acid prescription runs out.
B complex suggestions: Slightly cheaper options with inactive B6:
With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a separate daily B12 supplement (or B12 injections every 1-3 months)
After you finish folic acid prescribed by GP look at starting a daily separate vitamin B Complex
once your serum B12 is over 500 (or Active B12 level has reached 70), you may be able to reduce then stop the B12 and just carry on with the B Complex.
If Vegetarian or vegan likely to need ongoing separate B12 few times a week
Thorne Basic B recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule) Thorne can be difficult to find at reasonable price, should be around £20-£25. iherb.com often have in stock. Or try ebay
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 5-7 days before ALL BLOOD TESTS , as biotin can falsely affect test results
In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg) and continue separate B12
Post discussing how biotin can affect test results
Just testing TSH now is completely inadequate, but frequently all that GP will test
Hence thousands of U.K. patients test privately
Were thyroid antibodies tested at diagnosis?
Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine
For full Thyroid evaluation you need TSH, FT4 and FT3 tested
Also both TPO and TG thyroid antibodies tested at least once to see if your hypothyroidism is autoimmune
Very important to test vitamin D, folate, ferritin and B12 at least once year minimum
Low vitamin levels are extremely common when hypothyroid, especially with autoimmune thyroid disease
Has ferritin level been tested?
About 90% of primary hypothyroidism is autoimmune thyroid disease, usually diagnosed by high TPO and/or high TG 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)
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)
Essential to retest vitamin D, folate, ferritin and B12 at least annually…..more frequently initially
For good conversion of Ft4 (levothyroxine) to Ft3 (active hormone) we must maintain GOOD vitamin levels
Also VERY important to test TSH, Ft4 and Ft3 together
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)
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
What was your b12 level? A single shot is an unusual treatment. Generally b12 deficiency can either be controlled by diet - if is caused by diet, removing the absorption impediment- if it is caused by a drug for example or if it is some form of PA by shots for life and the starting point is shots every other day for at least two weeks and until no further improvement in symptoms. Thereafter shots at regular intervals such as monthly or weekly depending on the individual.
Many GPS in the UK are not particularly diligent in their treatment of b12 deficiency and many people self manage.
If there is no reason for deficiency, such as diet, then once tested and treated b12 retests are generally not a good idea as it could result in the medic declaring " your cured" and with holding treatment.
Book early morning test and last dose levothyroxine 24 hours before test
Presumably you are higher dose levothyroxine now
Guidelines of dose Levo by weight
approx how much do you weigh in kilo
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 somewhere near full replacement dose (typically 1.6mcg levothyroxine per kilo of your weight per day)
Adults usually start with a dose between 50 micrograms and 100 micrograms taken once a day. This may be increased gradually over a few weeks to between 100 micrograms and 200 micrograms taken once a day.
Some people need a bit less than guidelines, some a bit more
TSH should be under 2 as an absolute maximum when on levothyroxine
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).
