I recently reduced my erfa from 3.5 grains to 3 at end of September
For some reason Ft3 stayed same at 4.2 and Ft4 increased to 17 from 13.3, Medichecks.
I reduced from 3.5 grains to 3 because back in 2001 I didn’t have tachycardia at 3 grains and my TSH was 1.6, Ft3 4.2 and Ft4 was 13.2, at 3.5 grains I have tachycardia sometimes and my TSH is 0.008. Hertoghe said try reducing the dose slowly to 2.5, okay worth a try although many on here would disagree, he said he had patients get rid of the tachycardia by getting TSH back in to range. When his patients had tachycardia their Ft3 and Ft4 was in range.
However since my last cholesterol test with him my total cholesterol has risen from 7 to 7.9 and LDL risen from 4.73 to 5.41, my HDL. Is good at 2.07 so I have a healthy ratio of 3.81 and triglycerides of 1.04. I have only been on 3 grains about 6 weeks. So is the thyroid the culprit, has anyone had similar experiences. All other variables are the same except I take Ruxolitinib for polycythaemia which increases cholesterol but the dose increase this summer ie between the two tests was only only 6%.
has anyone any data on how much thyroid change changes cholesterol.
The strange thing is that reducing the thyroid from 3.5 to 3 grains hast reduced my ft3 or ft4 or restored TSH back in to range as it was in 2021 when I was on 3 grains, it’s still ver suppressed, maybe it needs more time but why no reduction in Ft3/4. Or are Medichecks labs not so accurate.
Or maybe slightly dehydrated.
