I have Graves' Disease, was diagnosed in April 2022. I started on carbimazole, and by the end of May/beginning of June last year, I was feeling much better.
I started to feel unwell again by September (fatigue, breathlessness, cramp in my feet, muscle aches and pains, heavy eyes, gritty eyes ...). My GP did my blood test in October (I stopped taking anything containing biotin a week beforehand), and my results were TSH 3.75 (0.27 - 4.20) and T4 13.6 (11 - 21.2). No T3 tested as those results are considered normal.
I referred myself back to my private endo, who recommended I reduce my carbimazole to 5 mg four times a week, then test again after 6-8 weeks.
I felt no better after the reduction, and my results in December were TSH 1.58 (same ranges as above) and T4 14.2. Endo recommended I reduce carbimazole again, to 5 mg three times a week. He wants me to stay on carbimazole for a year at least, in the hope of remission. He recommended my TSH should be around 0.5, and then T4 andT3 high enough in the range that I felt well.
I did Monitor my Health blood tests this week - I did vitamins too, but will put those results in a separate post for advice (!) - folate and ferritin were low, B12 and vitamin D were okay. I have, over the last week, been feeling a lot better. I even started to exercise again! I was surprised to find my results were:-
TSH 1.96 (0.27 - 4.2) - ranges slightly different from my local lab
T4 15.9 (12 - 22) - 39% through range
T3 4.3 (3.1 - 6.8) -32.43% through range
My T4 is obviously going up, albeit quite slowly (I'm impatient!). I was surprised that TSH had risen (blood test at around 8 am). As I'm feeling okay, I'm thinking I stay on the carbimazole dosage I'm on now, and see how I go, and retest in 6-8 weeks. Or, I could go back to the Endo? Not sure what to do.
