Right I noticed the low Free-T as well and that is part of my reason to return to injections which had been as high as 300mg per week but will just go with 200mg per week. By exiting with some PCT and allowing a shakeout period I can get the proper tests to learn if I am hypo etc.
The T seems to help my UC and I found research that T suppresses the immune system a little bit especially t-cells. I have been able to shutdown UC but then go back to eating too much processed food, not taking probiotics etc and wind up flaring. I am graphing all the data and it seems my problem is dehydration late summer in a dry mountain climate. Meanwhile spinach and sunflower seeds, psyllium seed powder ( not husk ), protein, coconut milk, l-glutamine and VSL#3 all help. 6 months since the last flare and that was not easy being on blood thinners.
