I have had a underactive thyroid for many years now and been on thyroxine for around 15 yrs. I’m on 150mg. They treated me with depression at the beginning and that nearly sent me over the edge. I must admit I’ve struggled with tiredness and being able to relax. I have had my bloods done and the doctor says my bloods are fine. I did ask my doctor this time to check my liver function, bilirubin ALT-ALP and that came out ok. I’m a bit over weight but not that much. I am very hungry especially at night and noticed my testosterone levels have dropped and wonder is it because I have a underactive thyroid?? I sometimes can have lots of energy and running 100 miles an hour or can wake up feeling exhausted. Please can any one give me some advice, will be very appreciated.
