Guest guest Posted October 31, 2008 Report Share Posted October 31, 2008 Craig, Excellent advise. Thyroid issues cause problems for millions of people: " More than 10 million Americans have been diagnosed with thyroid disease, and another 13 million people are estimated to have undiagnosed thyroid problems in the U.S. alone. Frequently misunderstood, and far too often overlooked and misdiagnosed, thyroid disease can affect almost every aspect of health, so understanding more about the thyroid, and the symptoms that occur when something goes wrong with this small gland, can help you protect or regain good health health. A February, 2000 research study found that the estimated number of people with undiagnosed thyroid disease may be 10 percent -- a level that is double what was previously thought. This may mean as many as 13 million Americans are currently undiagnosed. For women, the risk is even higher. A woman faces as high as a one in five chance of developing thyroid problems during her lifetime. That risk increases with age and for those with a family history of thyroid problems.

Guest guest Posted February 15, 2009 Report Share Posted February 15, 2009 , Would you be kind enough to reply with the volume and issue number information where you read those comments by Loren Chiu. I'm just curious and I'd like to read that article. Thanks, Tomasz Numrych, MS, CSCS City?
