Increasing Levo during pregnancy

[YoanaG]

Hi,

I am taking levo from January this year. The dose I am taking is 50 mg . Month ago, decided to increase with - 12,5 for two weeks, but experienced high heart rate and anxiety , ft4 was 20,5 (10,6 - 24,5). During that time I got pregnant. Now I am trying to increase it with only 6 mg ( I am not sure if that would be enough) 2 weeks ago before a new I was pregnant I started taking t3 - 3 mg as my ft3 was low. I feel very tired and exhausted when I take t3 but the anxiety goes away. Any tips? Ft3- 2.800(1.580-3.900) ft4 -0,980(0,700-1,480) tsh -1.590

I’m sorry you haven’t had any replies to welcome you & offer advice.

Very occasionally posts get missed & I think that’s what’s happened here.

My comment will bring your post back up the news feed so others will see & offer further advice.

50 mcg is a starter dose, were you diagnosed quite recently? It usual for dose to be gradually increased, usually every 6 - 8 weeks & if you conceive a 25mcg increase is recommended.

Have you had thyroid antibodies tested? TPO & TG antibodies?

In January your FT4 was high in range, but your FT3 might not have been.

Your more recent results show low FT4 & higher FT3. Had you started T3 when tested?

Most feel well with FT4 in top 3rd of range & FT3 above 50%. Did you take T3 prior to blood draw? as this can show a higher daily level.

Some are sensitive to dose changes, good core nutrients can sometimes help tolerate increases better.

Have you tested folate, ferritin, B12 & vitamin D? Add results & lab range. In range is not same as optimal.
