I just had a standard blood test and the results for tsh was 3.47mU/L. I heard there's alot of debate amongst scientists/doctors about what is the normal range for tsh. Can anyone tell me if this is cause for concern? And could this level be due to eating a low calorie diet? If not what could be causing this? I'm 24 and feel I have a healthy diet (fruits, vegies, wholegrains, milk, tofu etc.. ie not high fat).
Any help would be appreciated.
