All:
I would encourage those of you who have quit smoking (and, of course, current smokers as well) to ask your doctor to check your thyroid: TSH and Free T4 at a minimum. I would also suggest that you continue to request the test during yearly physicals.
There is a lot of information on the web regarding the link between smoking and thyroid disease. Here is are two links: http://quitsmoking.about.com/od/smokingandthyroiddisease/Smoking_and_Thyroid_Disease.htm
http://thyroid.about.com/cs/latestresearch/a/smoking.htm On page 2 of this link is a section on the relationship between quitting smoking and thyroid disease onset.
Google Smoking and thyroid disease.
I'm a 49 year old, post menapausal women who quit smoking in July 2006. For the next 9 months I suffered with thyroid disease without knowing what was wrong with me. You're supposed to feel better after you quit smoking, right?
I wish someone had told me, or that my doctor had known about the link between smoking and thyroid disease. It would have made it all so much easier.
Thus, I am sharing this with all of you in the hope that you get your thyroids checked.
Good luck and stay smoke free. It's worth it!
