I posted before with my background and previous results, the post is here: healthunlocked.com/thyroidu...
I had my dose increased to 150 mcg about 5 weeks ago, these are my results from today (morning sample, fasted and I took my levothyroxine for the day after my test):
TSH: 0.03 (0.27 – 4.20) (down from last result)
T4: 19.4 (12.00 – 22.00) (74% through range by my calculation, up from last result)
T3: 5.2 (3.10 – 6.80) (57% through range by my calculation, up from last result)
Ferritin: 53.1 (22 – 275) 6th July: 43.3 (up from last result)
Haemoglobin estimation: 121 (120 – 150) 6th July: 130 (down from last result)
Red blood cell count: 3.80*10^12 (3.80 – 5.30*10^12) 6th July: 4.03*10^12 (down from last result)
Mean corpuscular volume: 98.4 (83 – 100) 6th July: 100.7 (down from last result, which was abnormal)
Mean corpuscular haemoglobin: 31.8 (27 – 32) 6th July: 32.2 (down from last result, which was abnormal)
At my last blood test my folate, vitamin D and B12 were all optimal so not a concern.
I generally feel better now I'm on 150 mcg, my feet are usually nice and warm which is a completely new sensation for me, and I'm a bit more clear headed, my periods don't last 8 days anymore, and I only have one day of heavy bleeding now as opposed to 4 days of heavy bleeding but I'm still losing so much hair (it's been falling out excessively since March) and I really struggle to recover from exercise. I am still suffering from brain fog quite often as well and my mood is quite low most of the time.
I don't understand why my ferritin has gone up but haemoglobin has gone down. Also don't understand why my red blood cell count has gone down again (I have had a low/close to low RBC from 2018 until earlier this year when I started taking 420 mg ferrous fumarate/day and it became "normal" again, but now it is borderline low again. I'm still taking the ferrous fumarate (have been since February/March because I'm trying to increase my ferritin and recently started eating red meat again to try to help.
150 mcg lactose free levothyroxine (Teva, same brand I've always used)
2.5 mg low dose naltrexone (have been taking since June, slowly titrating up dose by 0.5 mg every two weeks. I started on 0.5 mg)
420 mg ferrous fumarate
Please can anyone advise on why I'm still having thyroid-related symptoms despite T3 57% through range? And why I'm losing so much hair? I also had a few white eyebrow hairs but since the dose increase to 150 mcg I can see those white hairs have started to grow brown again. So so weird, I'm only 33, who gets white eyebrow hairs at 33?
