A Basic Overview of hyperthyroidism focused on primary hyperthyroidismAs depicted in the diagram, in 'primary hyperthyroidism' the TSH is usually low because decreased feedback of thyroid hormones from the thyroid gland causes the pituitary to stop stimulating the thyroid gland to produce more hormone. This TSH value has a very wide range of normal and there are some common misconceptions about the test. The endocrinologists at Houston Thyroid and Endocrine Specialists will review your symptoms in conjunction with blood analysis to determine if there is a problem. Depending on the exact cause of the low thyroid function, medical treatment of hyperthyroidism may or may not be indicated. |
