Her TSH is not low enough. Should be 1 or lower or suppressed for some people. Doctors unfortunately think a low TSH may cause a heart attack or osteoporosis but these are rumours. Her Free T4 and FT3 are too low and should be towards the upper part of the range.T3 is the active thyroid hormone which is required in all of our receptor cells and enables our metabolism to work normally (heart, brain, everything in fact). Should be towards the top of the range.
Levothyroxine is T4 only (inactive) it's job is to convert to T3 so we have to be on an optimum dose. Some people are poor converters of levothyroxine and can feel better if some T3 (liothyronine) is added. The British Thyroid Association have recently stopped GPs from prescribing which has caused immense worry for those who are well on T3 only or addition of T3.
Also check B12, Vit D, iron, ferritin and folate as deficiences can also cause problems.
Blood tests should be at the very earliest, fasting (you can drink water) and allow a 24 hour gap between last dose of levo and the test and take afterwards.
Levo should be taken on an empty stomach with one full glass of water and wait one hour approx before eating. Food interferes with the uptake.
Always get a print-out for her own records and she can post if there's any query.
