Thyroid Disease: An Overview
There are many types of Thyroid Disease. To bring attention to the different disorders, we are featuring a different Thyroid topic each month. For the month of September we are presenting an overview of Thyroid Disease.
The thyroid gland is butterfly-shaped and is located in the front of the neck attached to the lower part of the voicebox (or larynx) and to the upper part of the windpipe (or trachea).
- TSH (Thyroid Stimulating Hormone): Measurement of TSH using a sensitive assay is presently the recommended initial screening test when thyroid disease is suspected.
- T3/T4 testing: Measurement of blood thyroxine (T4) or triiodothyronine (T3) is performed when the TSH test is abnormal to determine the extent of the thyroid abnormality.
- Radioactive iodine uptake and thyroid scan
- Thyroid ultrasound
- Thyroid antibodies
- Thyroid biopsy
Treatment of Thyroid disease depends on the type of thyroid disease you have.
- Hypothyroidism: Levothyroxine replacement, synthetic or desiccated
- Hyperthyroidism: Radioactive iodine, anti-thyroid medications, beta blockers or surgery (thyroidectomy)
- Hashimoto’s thyroiditis: Levothyroxine replacement, synthetic or desiccated
- Nodules: Radioactive iodine, anti-thyroid medications, surgery
- Graves’ eye disease: Corticosteroid drug, Oral prednisone, orbital decompression surgery
- Thyroid cancer: Surgery, thyroid hormone therapy, radioactive iodine, external radiation therapy, chemotherapy
