I've just been told I have to start taking Levothyroxine, as my cholesterol came out high and my thyroid stimulating hormone is 5.74, my free thyroxine is 11.9, in a recent blood test. Slightly shocked, as I'm otherwise fairly healthy, very fit, and more under than overweight (5'7 and 58kg) - I'm 53, and having now tried to read up on symptoms, only ones I may have is I'm always cold, always have been, get tired, but thought that was normal - I do take HRT, since last year - worried this could affect the thyroid (saw there's a link between progesterone and thyroid?).
I've read a few posts on here - my Vit D is perfect, as is my iron. Had extra blood tests last week, waiting for copy of results (T3/4?).
Any advice on anything welcome, as no idea what to expect!
Also, will this drug make me put on weight? Or have horrible side effects?
