I’ve had hypothyrtsince 2004 and for the first 9 years was taking 100 mcg/day with an annual blood test. The last 6 years my tsh levels have been up and down with the gp altering my doses.
Recently, saw an endochronologist - tsh 0.5, FT4 26. He would not check FT3 or antibodies. I have symptoms of hypothyroidism all the time (tired, constipated, heart rate 46, dry skin, brain fog, etc). He suggested I reduce my dose (currently 100 for 5 days plus 112.5 for 2 days = 725/week) by 12.5 mcg per week. I worry that my tsh will increase. I thought taking too much Levothyroxine would make me hyper not hypo? He has checked vitamins, full blood count, liver function test, B12, Vit D, coeliac disease, diabetes and all normal. I mentioned about checking my FT3 but he said it’s not in the NHS guidelines.
My GP checked my FT3 in January and it was 4, tsh 0.5, FT4 18 on a dose of 750 mcg Levothyroxine per week - still felt hypo. Any advice would be welcome.
