Perhaps you are one of the 13 million people in this country that go to your doctor with sudden weight gain, fatigue, hot flashes, infertility, depression, or some other unexplained symptom. The symptoms are considered vague by them and they order basic blood work. They send you out for blood work that comes back "normal". They may test your TSH - Thyroid Stimulating Hormone and that may come back in the "normal" range. The problem is that the range is broad 0.5 to 5. That is a very wide range of "normal". 

According to the American Academy of Clinical Endocrinologists (AACE), there are 27 million people in this country with thyroid conditions and only half (13 million) are diagnosed. That makes hypothyroidism the #1 underdiagnosed condition in the United States. Some experts estimate that more than 80% of Americans have a thyroid condition and are not diagnosed properly. The truth is you can go 20-30 years with symptoms before your blood work is abnormal. Finally, when it becomes abnormal, your doctor will put you on thyroid replacement hormones for the rest of your life. Is there another answer?
