    Thyroid cancer Missed period

    Im 27 I had 4 I-131 treatments and my thyroid removed. Its been almost a year and a half since my last period. I take 112 mcg synthroid everyday. I can't see my doctor until November and im anxious somethings wrong. Has anyone had any problems with infertility?

      Hello. If you want to research that further, it is called "secondary amenorrhea." http://www.nlm.nih.gov/medlineplus/ency/article/001219.htm

      I am not a doctor, but I looked into how they may go about evaluating secondary amenorrhea. It looks like the problems you've had with your thyroid and your medication Synthroid can have that affect on your period due to hormonal changes. like the TSH Thyroid Stimulating Hormone. On the paper with the little tiny fine print that comes with medications, for Synthroid adverse reactions, it lists menstrual irregularities, and impaired fertility. http://www.rxabbott.com/pdf/Synthroid.pdf So this is definitely something you want to take up with your doctor, or at least notify them about that, and tell them the reason why you cannot see them until November. By waiting, you never know if it could cause other problems.

      Here it says to contact your doctor if you have changes in your menstrual periods when taking Synthroid http://www.drugs.com/synthroid.html

      Good luck. hope you find an answer soon.

      Thyroid directly affects your hormones. When you ready to have children you need to make sure that your thyroid levels are correct by seeing a specialist. I had stage IV in high school and did not see a specialist. I had several miscarriages in my 20's because I did not know about this. I had my daughter at age 30, she is 23, healthy and married. I do not know how much radiation I had when I was treated since it was experimental at the time.
      112 is not a very strong dose for a full replacement, I would expect it to be higher for a cancer prevention.
      I hope I have helped ease your mind, Take care - Tracy
