I’ve had 5 SHGB tests I think. 4 while I was doing 16:8 intermittent fasting and my SHBG ranged from 31 to 38 for the last one while IF. I was not on armour thyroid at all for any of these tests.
I was not fasting for the reading of 27 and was on 90mg of armour daily for at least 3 months. I’m not sure armour had any impact on my SHGB.
I recall 2 things physioLojik mentioned.
- SHBG was impacted by insulin.
I think of it like Higher insulin = Lower SHBG, lower insulin = Higher SHBG. Which kinda makes sense looking at my SHBG numbers while fasting (reduced insulin) vs non fasting (higher insulin).
- Taking armour thyroid speeds up metabolism of drugs.
“when you increase your thyroid everything speeds up - including metabolism of drugs. Your estrogen levels can drop on thyroid meds.”
I’m not sure about this in my body just yet, but I would say a sensitive E2 reading of 41 compared to TT of 1192 could be considered low.
I’m actually thinking about increasing my dose too to see what happens. I really want to get my diet in a better place, but really thinking of going to 46mg EOD…and I’ve also consider going IM too to increase E2, but still undecided.
Let us know what you do and how you feel, very interested to hear.
