I would love to understand more about my thyroid. I’ve been on Levothyroxine since diagnosis some 20 years ago. It’s crept up to 175mcg last week. Here are my latest bloods from my GP.
TSH 2.71
Free t4 14
Ferritin 84
Folic Acid 15.5
Vitamin D 95
I am on b12 injections and supplementing with folic acid, vit D, ferrous sulphate, vitamin C, B complex, fish oil, magnesium.
I’m gluten free now, no caffeine, no alcohol and a non smoker. Not much sugar and try to eat clean food. Could always do better but trying my best.
I still feel awful. Piling on the pounds. Hard to do even gentle exercise, breathless, dry itchy crawling skin, muscle and joint aches. Low back ache is awful and can’t stand for long. I have a rowing machine and aim for 20 minutes a day.
I think the palpitations have reduced since upping to 175mcg.
If anyone is knowledgable about genes, I can confirm, through my own digging around in my DNA, that I have these mutations:
Rs1801133 AG
rs1801131 TG
rs17606253 TT
Rs11206244 TC
Rs2235544 AC
The top two are, I believe, the DIO1 and DIO2
The third one possibly t4-t3 conversion
The bottom two to do with decreased thyroid hormone metabolism in tissues.
I have no idea what these mean or what the letters mean. Any help would be so appreciated S I feel like my health is slipping away from me.
thank you.

I'm not surprised you don't feel well with a TSH that high! Not that TSH itself causes symptoms, it doesn't. But it's high because your thyroid hormone levels are too low.
Impossible to tell how low that FT4 is, because you haven't given the range - ranges vary from lab to lab - and they haven't even tested the FT3 (because they don't know what it is!) but I'm guessing (based on the TSH level) that your FT4 is low and that means your FT3 is going to be even lower.
Impossible to tell how well you convert without an FT3 result tested at the same time.
But the strange thing is that you're on quite a decent dose of levo, so why isn't your FT4 higher? How do you take it? On an empty stomach leaving at least an hour before eating or drinking anything other than water? And at least two hours away from other supplements/medication - four hours away from vit D and magnesium? So many things can affect absorption so we have to be careful.
Thank you for taking the time to reply. I’m so grateful.
Here are the ranges.
TSH 2.71 [0.35-5]
Free t4 14 [9-20]
Folic Acid 15.5 [2.7-34]
I take my thyroxine as soon as I wake up, with water. I wait an hour before eating breakfast and then take 10k iu of vitamin D, B complex and 5mg folic acid.
I never miss a dose.
I haven’t felt well for years. I just really want to get to the bottom of things.
I could try changing the time I take my vitamin D. I tend to take magnesium later in the day.
So, your FT4 is too low, which will mean your FT3 is lower, so that's why your TSH is high.
There should be a gap of at least four hours between thyroid hormone and vit D, so that could be affecting your absorption of levo. Good idea to try taking it later.
For the B complex it should be about two hours. Which B complex are you taking? Because if it's a good one with 400 mcg methylfolate, you don't need to take the folic acid as well.
I take Boots own brand. It’s got methylcobalamin in it - 25uh
I had no idea about the vitamin D. Why don’t the GP’s advise patients of this?
I have had to endure an 18 month ordeal to educate GP’s on pernicious anaemia and to be frank, been really mistreated. I can’t believe I’m heading for the same with my thyroid. I’ve been waiting 18 months to see an endocrinologist and found out that they cancelled the referral in September and I’m not even in the system now!
Well, folic acid isn't the best form of folate. You'd be better off with one that contains methylfolate. Thorne do a good one: Basic B.
Levo isn't absorbed in the stomach so I don't know if gastritis or inflammation would hinder it. But, it does need good levels of stomach to detache the hormone from the pill. It's then absorbed in the gut. So, make sure you have good levels of stomach acid.
Re gastritis, I didn’t know that it wasn’t absorbed in the stomach. I do suspect I have low stomach acid though. This could be another possible explanation. I take kefir to help my stomach but acid isn’t something I had considered.
Stomach acid is a very important part of the puzzle. Try the burp test:
drink half a glass (4 ounces) of cold water with a quarter teaspoon of baking soda, on an empty stomach. Then time how long it takes you to burp. If it takes longer than three to five minutes, the theory goes, you don't have enough stomach acid.
