So after being on 88mcg of Synthroid for 4 weeks I got my latest lab results. I am so puzzled, confused, trying to stay optimistic and patient as difficult as that is.
After being on 100mcg for around 8-9 weeks total I asked the doctor to decrease my dose as I experienced more frequent bowel movements (hyper symptom). I wish he had run the labs at the time before switching me.
My recent lab is after 4 weeks on 88mcg Synthroid and one before that was on 6 weeks on 100mcg, with record of earlier ones too (on 6 weeks each of 75mcg, 50mcg, 25mcg).
TSH 0.66, 0.57, 2.19, 1.70, 2.87 (0.32 - 5.04)
Free T4 14.5, 17.8, 14.1, 13.5, 13.4 (10.6 - 19.7)
Free T3 3.94, 3.89, 4.06, 3.94, 3.88 (3.00 - 5.90)
Ferritin was 149 (24 - 444), Vitamin D 84 (75-150). I regularly supplement with D3 10,000/week and take a B-Complex and B12 1000mcg Methylcobalamin daily. TPOab and TGab have been in range for years.
So while the T4 dropped, the T3 improved on 88mcg Synthroid. On the 100mcg Synthroid, while the T4 had gone above the 75% of range, the conversion was lacking and T3 Free was less than it is now. I don't want to experience the frequent bowels I had on that dose.
I've only been on 88mcg Synthroid for 4 weeks so would like to be patient and give it either another 4 or 6 weeks before rerunning labs. I am not sure but I may be feeling "fuller" more easily these days, and passing more gas (slower digestion), possible hypo symptom. I am trying to decide between simply giving the 88mcg Synthroid another 4-6 weeks or to do that but also start taking it in the late evening before I sleep (on empty stomach 2-3 hours after last meal) to see if that helps. Currently I take it in the morning, an hour before breakfast.
