Should I start medication if my T4 is 5.2?

Posted , 1 user is following.

I've noticed that most experiences show rather big numbers for T4. Mine is 5.2 but it was 4.6 in April and 3.2 last year -so it is climbing up.

I don't know my TSH etc. Out of all the symptoms I've got only extreme fatigue. I've been under stress for quite a while and though my GP agrees that stress can cause fatigue but she insists that increasing T4, now being over the norm, should be dealt with so I would need to start 50 mcg of levothyroxine.

Please need your advise -should I wait a bit longer and hope for the next blood test to be normal or should I start taking tablets before it's got worse?

    I would start taking it - it looks like you have the condition - my TSH level was 6.2 and I started on 25mcg, which increased to 50mcg as I didn't improve. I still felt bad and my next result was 4.8 but the doctor still increased my dosage to 75mcg. My TSH level seems to have stabilised a little now, it's at 2.51.

    I would listen to your doctor's advice - it's not nice for it to get worse - believe me - my dad wasn't diagnosed for months because he had some of the rarer symptoms such as gruff voice and painful/numb hands and eventually couldn't even walk to the bathroom - he had to crawl.

    Unfortunately I have inherited the condition from him!

    Good luck.

    if i remember correctly, ref ranges are 0.2 -2.5 and the higher the result the more underactive, my initial result was 50.2! you are borderline, request another test in 6 months time, are you symptomatic?

    My level is 4.3 but my doctor won't help because my autoimmune system is ok he says i have to up as far as 10 before he even thinks about giving me tablets. Which is crap as i have been feeling fatigued and depressed for over a year. Does anyone know if a traumatic event can cause this?
