I was originally diagnosed in 2021 with Hypothyroidism., after noticing hair loss as the main symptom. I am on 75mg Levothyroxine since 2022, but now suffering significant and worse hair loss, feeling cold hands and feet most of the time. I have lost a chunk of weight(a few stone) as a result of being diagnosed T2 and have reversed that, not sure if this is a factor that would affect my dosage of Lego.
Just had blood test back - see below. My conversion seems low, but concerned doc will not do anything as they are ‘normal’ ranges.
Appreciate any guidance or insights.
Thank you

Your T4 is around 60% but T3 just 10%.Conversion around 4.9. Two years is a long time to be stuck on 75mcg levo.As you know by reading on here it can be a battle getting any increase as they only use TSH.
You could take those test results with you to your GP and make a list of your symptoms.Further down the line you may end up like myself adding a little T3 but it's much too early as your on low dose levo.Your defo ready for 100mcg daily.
Test collection was at 10:25 but was only water, but I did take my levo about 8am. (I had not read the guidance about 24 hours before test - would that improve or worsen results?)
Brand is Teva (pretty much always been given that brand apart from very early days). Been on this one for 2 years.
Folate range 3-20 ug/L
I take a zinc and selenium supplement - Biocare Microcell- Nutriguard plus, Methly B complex, Vitamin D3 (1000 iu) and Nutrition Magnesium Glycinate in the evening (2x100). All supplements are taken with food, and at least 3 hours from levo.
Will ask for appointment and ask for further tests/retest.
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).
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.
The optimal daily dose in overt hypothyroidism is 1·5–1·8 μg per kg of bodyweight, rounded to the nearest 25 μg.
Some people need a bit less than guidelines, some a bit more
I take a zinc and selenium supplement - Biocare Microcell- Nutriguard plus, Methly B complex,
Did you stop vitamin B complex 5-7 days before test?
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)

Hair loss is really upsetting me! Any info pls? :'( 
Hair loss: slightly high TSH vs. low ferritin?
Help interpreting my blood test. 
My GP says my thyroid is normal and that I'm suffering from anxiety and stress. I'm not anxious or stressed .....
