Your thyroid helps every cell in your body to be happy and healthy. Thyroid hormones are like the spark-plug of an engine, or the yeast in the bread batter.
So when the thyroid isn't working or the thyroid is blocked from working there is a wide range of symptoms. Thyroid problems come in two basic varieties. One, problems with the thyroid gland itself, and two, problems with other areas of metabolism that can prevent the thyroid hormones for reaching their target in the calls.
If you suffer from any of these symptoms, get checked out by a doctor who is going to run a full panel of thyroid lab tests, not just a few tests.
Many sufferers may have thyroid related symptoms, but the real problems may be related to other body systems. Liver problems and blood sugar problems can block proper thyroid hormone action.
Don't put up with years and years of suffering.
