TSH fluctuates throughout the day so TSH is higher in the early morning and lower during the afternoon and evening.
Thyroid peroxidase antibodies are positive for autoimmune thyroid disease (Hashimoto's) and this can cause fluctuations in TSH, FT4 and FT3.
There is no cure for Hashimoto's which causes 90% of hypothyroidism. Levothyroxine treatment is for the low thyroid levels it eventually causes. Many people have found that 100% gluten-free diet is helpful in reducing Hashi flares, symptoms and eventually antibodies and it may delay progression to hypothyroidism.
TSH >2.0 indicates your thyroid is beginning to struggle but FT4 15 and FT3 5.3 - 6.5 are usually within range and euthyroid (normal). Perhaps you could ask for the lab ref ranges in future as it makes it easier to advise. You are not likely to receive a NHS diagnosis of hypothyroidism until TSH is over range (usually >5.0) or FT4 is below range.
Thanks clutter, tests in June and these last ones were done at 9am, I don't understand why TSH has been creeping up then started to come down only on this last test
Grey goose, I feel like it's 1 step forwards and 2 steps back, just when docs said if TSH levels have gone up she would start treatment. I see my dr next week to see what she's going to do.
Well, that's going to happen when you have antibodies - and she should know that! And she should be treating you anyway, as you have antibodies. Plus, you are actually hypo when your TSH hits 3. So, not surprising you have symptoms.
My symptoms are severe tiredness, splitting nails, constipation, loss of sex drive, stiff joints, dizziness, mood swings, dry mouth, post nasal drip, dry skin, dry gritty eyes, brain fog. The list seems endless
I have all those symptoms plus weak legs and arms, numbness and tingling in legs and arms, adrenaline type surges that wake me up, etc. The list IS endless! I'm so tired of all this!
