Thyroid hormones control the female body’s metabolism. The brain produces thyroid stimulating hormone (TSH) which triggers the thyroid gland to produce two types of hormones T4 and T3. In hypothyroidism, the female body has inadequate levels of the thyroid hormones. This often leads to imbalances in relation to other hormones. Hyperthyroidism is a less common condition that exists when excess thyroid hormones are present. Because every cell of the body is affected by thyroid hormones, symptoms of imbalances are often varied and affect multiple body systems.
