I just received a call from my doc. office this morning to let me know that my TSH level is 6. I am 40 years of age with a large amount of stress, I just lost my husband June 22 to lung CA which had spread to his adrenal glands. I have put on 20lbs in the past year but have blamed it on stress and the fact that I quit smoking, I am returning in one month to retest. Should I be concerned and what could be the out come or treatment?
