Thyroid hormones directly affect the heart and peripheral vascular system. They increase myocardial inotropy and heart rate. Also, T3 reduces systemic vascular resistance.
Toxic environments, chronic stress, frequent antibiotic therapy, genetic disorders, infections, nutritional disorders, radiation, hormone imbalances, smoking and tumors can all cause the thyroid to function improperly.
Hyperthyroidism occurs when your thyroid levels are too high. This is much less common than hypothyroidism (low levels). Excess levels of thyroid hormones, especially T3, can produce grogginess, heart palpitations, high blood pressure, anxiety, weight loss, an intolerance to heat, diarrhea, excess sweating, bone growth and protruding eyes.
Hypothyroidism occurs when your thyroid levels are too low. 17% – 40% of the population suffers from an under active thyroid whether or not they’re aware of it. It seems to be more common in women and elderly people. As you age, your thyroid levels decrease. The conversion of T4 to T3 declines, and your receptor intake sights become less sensitive to conversions. There are three different levels of hypothyroidism: primary, secondary and tertiary.
