A year ago my elderly mum's annual thyroid blood tests were excellent on 100 mcg Levo (TSH 0.2, FT4 22). Since then she has gained several stone in weight, due to taking steroids for a lung condition that makes her very poorly, and I believe she needs an increase in thyroxine. Latest blood tests came back "normal, no action required", despite TSH gone up to 3.32 [0.2 - 5.0] and FT4 dropped to 13.3 [9.0 - 21.0].
Does anyone have any solid medical references that I can use to convince her GP to increase her thyroxine, given that she clearly is clueless about optimal levels? I have the Dr Toft quotes from his "Understanding Thyroid Disorders" book. Anyone got anything else I can use?
Any help much appreciated! xx
