Most conventional physicians are trained to diagnose low thyroid primarily with the blood test. This test is good for detecting evidence of a weak thyroid gland but cannot tell you if the person is efficiently utilizing the thyroid hormone. The inefficient use of thyroid by the body has been called "thyroid resistance."
Symptoms of low thyroid / thyroid resistance:
- fluid retention
- hair loss
- impaired memory/concentration
- irritable bowel
- weight gain
- dry skin/hair
- muscle and joint aches
- elevated cholesterol
- increased nicotine/caffeine use
- heat and/or cold intolerance
- frequent colds/sore throat
- cold hands/feet
- easy bruising
- slow wound healing
Basal body temperature is also used to assess the metabolic rate, which is slower than normal in these cases. (Underarm temperature (mercury thermometer) for 10 minutes first thing in the morning before getting out of bed) should be 97.8 to 98.2 degrees farenheit). Orally (digital thermometer) should be 98.6. If your temperatures run lower than these normal values and you have symptoms on the above list which are significant, you may have a low thyroid either due to a weak thyroid gland or thyroid resistance.
This problem can be successfully treated using nutritional and (natural) hormonal intervention.
