Thyroid hormone plays a major role in regulating different functions in the body and balancing the metabolic rate. When thyroid is malfunctioning many organs in the body will suffer. Often a patient may have all the symptoms of hypothyroidism such as hair loss, brittle nails, constipation, dry skin, poor memory, poor concentration, and cold sensitivity and yet blood tests such as TSH may be completely within normal range. Most likely patient’s basal body temperature is low and reflexes are slow. If a patient presents with subclinical hypothyroidism, Dr. Lalezar will recommend a natural thyroid hormone along with supplements that would enhance thyroid receptor sensitivity. Heavy metal detoxification and adrenal supplements are also very helpful in reversing hypothyroidism. Heavy metals are responsible for conversion of T4 to RT3 which in effect competes with active T3 and causes symptoms of hypothyroidism. Chelation therapy reverses this poor conversion of thyroid hormone and restores optimal thyroid function.
