So a quick summary of my previous posts, I switched from 100mg Levothyroxine to Natural Desiccated Thyroid (Thiroyd from Thailand) 3 months ago.
After 3 months my symptoms are still the same, very drowsy, tired, brain fog, bad memory, etc. I'm now on 2.75 grains per day, increasing by 0.25 grain about every fortnight.
I just got some blood test results, the first blood test since starting NDT. They are:
TSH 0.045 (0.55 - 4.78)
FT4 9.91 (11.5 - 22.7)
FT3 5.77 (3.5 - 6.5)
That's all that was tested by the doctor. My plan is that I'll test again privately in March for thyroid values plus iron, vitamin D, B12, etc.
My blood test results before switching to NDT were:
TSH 0.65 (range 0.27 - 4.2)
FT4 15.3 (12.0 - 22.0)
FT3 4.3 (3.1 - 6.8)
Anti-TG antibodies 12.1 (0 - 115)
Anti-TPO antibodies <9.0 (0 - 34)
25 OH Vit D 74 (50 - 200)
Active B12 81 (25.1 - 165)
Ferritin 86 (30 - 400)
Folate serum 12.9 ( > 2.9)
So, are my latest results what you'd expect? I expected the TSH to be suppressed after switching to NDT, which it is. I expected the FT3 to have increased, which it has. I was hoping for FT4 to at least be around the bottom of the normal range, but as it's outside the normal range perhaps that would help explain why I still feel fatigued and brain not functioning great.
I'm planning to keep increasing the NDT over the next 3 months. As I reach around 4 grains per day maybe I'd expect the FT3 to be higher towards the top of the range and for FT4 to have increased to be in the bottom of the normal range......and hopefully I'll be feeling like a new man?!
By the way, before starting with thyroid medication in 2012 my TSH was only 4.42 (0.3 - 4.2) & FT4 13.5 (12.0 - 22.0), so I wouldn't say it's conclusive that my underlying symptoms are thyroid related. Opinion is divided.
I'm taking a bunch supplements to help increase vitamin levels, e.g. 6,000mcg sublingual B12, 5,000 IU per day of liquid Vit D3, 65mg ferritin, selenium, etc.
