Excerpt from Dr. Lanzisera’s Thyroid Report, “THYROID DISORDERS EXPLAINED, Why Do I Still have Symptoms?”
First, let’s learn more about how the thyroid works…
In healthy people, the thyroid makes just the right amounts of two hormones, T3 and T4. These hormones have important actions throughout the body. Most importantly, they regulate many aspects of our metabolism, affecting how many calories we burn, how warm we feel, how much we weigh…and our general well-being.
Thyroid Hormones are in Charge of our Metabolism
Thyroid hormones also have direct effects on most organs, including the heart which beats faster and harder under the influence of increased thyroid hormones (this is why heart problems can often accompany chronic thyroid problems in women, and perhaps why heart problems are more common in women under the age of 50).
T3 is the more biologically active hormone (it’s more important for cellular function), and in fact most of T4 (80%) is converted to T3 in the body’s peripheral tissues. So T4 is just a precursor for the more active hormone, T3.
One of the problems in some thyroid disorders is that you may have trouble converting T4 to T3 in your tissues (have you been checked for this?). This can create a deficiency of T3, disrupting the body’s ability to properly regulate metabolism…leading to specific symptoms.
The symptoms of thyroid disorders, including hypothyroidism and Hashimoto’s, vary from extreme fatigue to dry, thinning hair. Thyroid disorders can affect the way we look, the way we feel, and even the way we think.
Some of the more common symptoms are fatigue, cold hands and feet, requiring excessive sleep, gaining weight easily, neck and back pain, constipation, depression,headaches, thinning hair, dry skin, heavy or irregular menstrual periods.
There are other symptoms that are less often associated with a thyroid problem as in a hoarse or raspy voice, yellow tinge to the skin, slower thinking, slower movement or speech, slow heart rate, and infertility. Children can also be affected by a low functioning thyroid gland.
