Signs and Symptoms of Hypothyroidism

Thyroid Gland

Hypothyroidism affects many people. It is a condition with many potential symptoms, some more common than others. However, because everyone has different genetic makeup, nutritional inputs, exercise level, toxin exposure, etc., your individual set of symptoms will vary from those of someone else.

If you feel you have the symptoms and been told your “thyroid levels are normal”, especially if you have received no other answers for your symptoms, you may be clinically hypothyroid. Thyroid tests are not 100% even when looked at in a detailed fashion. It is really your signs and symptoms that should guide you and your doctor. “Listen to your patient, they will tell you what they have” is a quote from one of our medical school professors. It is the guiding principal and cornerstone of good medical care.

If you have been diagnosed with hypothyroidism and have been put on Levothyroxin or Synthroid (both of which contain only T4) but still have symptoms, it is likely you are still hypothyroid and need Bio-identical Hormone Replacement Therapy (BHRT) that includes both T4 & T3. Studies show that T3 & T4 hormone replacement improve symptoms better than T4 alone.
