I was diagnosed with hypothyroidism and have been taking Thyroid Extract (Armour) and Slow Release T3 since 2015. With many symptoms at that time my TSH, Free T4 and Free T3 were low normal and I had a reverse T3 of 640, with the Ref. Range 140-540 (Australia). Initially I worked up to 90 mg thyroid extract and 40 mcg slow release T3, and the Reverse T3 quickly came down to mid-range. But my slow release T3 dose was halved after a few months when tests showed my Free T3 had gone above range and my TSH was down to almost nothing. The only thing that improved dramatically for the first 6 months on medication was my hair which thickened and began to grow back all over (have always had baby fine hair and since my 40s severe hair loss - am now 67), though undeniably I felt better with more stamina and some weight loss. Since then however I've gone backwards and feel unwell most days. I've unsuccessfully tried to adapt my dose according to symptoms (supported by my doctor) and am currently only taking 30mg thyroid extract and 20 mcg slow release T3. This may be totally inadequate but I have a problem with medication building up in my system causing cardiovascular symptoms and more severe muscle and joint pain. I've been off meds altogether a few times to clear my system and within a week or so have awful problems with eyes, dry mouth, and restless legs. I'm writing this in the hope that someone who has had similar issues can offer advice and am including my latest blood tests from May. Blood results dating back to 2003 have always shown a low TSH and lowish Free T4 and Free T3. In 2011 I was told I was a poor converter from T4 to T3. (This may or may not be relevant). Many thanks.
2018 TSH 0.78 Ref. Range (0.5-5.5)
FT4 12.5 (9.0-19.0)
FT3 3.6 (2.6-6.0)
