I had a total thyroidectomy about 10 yrs ago and have been taking Synthroid (brand) since my surgery. For the most part I was feeling okay but within the past 8 months I have been feeling lousy with rapid weight gain. I self paid to get some labs done to check my Free T3, and realized that my T3 levels were on the lower end . My Physician does not seem concerned about this and does want to consider prescribing synthetic T3 or NDT. I would like feedback from anyone who has tried the Thiroyd from Thailand or who can give me some advice.. Currently taking Synthroid 125 mcg and have been on this dose for the past 2 years. I am posting my most recent lab results, done about 2 weeks ago. TSH =2.19 Range 0.40-4.50 T4 TOTAL =7.2 Range 5.1-11.9 T3 TOTAL =76 Range 76 -181 T3 FREE = 2.4 Range 2.3 -4.2 T4 FREE =1.2 Range 0.8 -1.8.
