Thyroid disease: Description, Causes and Risk Factors: Alternative Name: Thyroid disorder. Thyroid diseaseThyroid disease is a small gland found at the base of your neck, just below Adam's apple. The thyroid produces two main hormones called T3 and T4. These hormones travel in your blood to all parts of your body. The thyroid hormones control the rate of many activities in your body.

Other causes may include, treatment of hyperthyroidism, radiation treatment to certain cancer, and in rare cases pituitary gland can cause hypothyroidism. A thyroid nodule is a swelling in one section of the thyroid gland. The nodule can be solid or filled with the fluid or blood. A goiter is an abnormally enlarged thyroid glands.

  • Radioactive iodine uptake test. For this test, you swallow a liquid or capsule containing a small dose of radioiodine. Then, a probe placed over your thyroid measures the amount of radioiodine in your thyroid. A high uptake of radioiodine means that your thyroid is making too much of thyroid hormones. A low uptake of radioiodine means that your thyroid is making low or enough thyroid hormones.
  • Thyroid scan. Thyroid scan usually uses the same radioiodine dose that was given by mouth for your uptake test.
  • Thyroid fine needle biopsy. This test is used to see if thyroid nodules have normal cells in them.
  • Thyroid ultrasound. The thyroid ultrasound helps your doctor to tell what type of nodule you have how large it is.
Treatment: The choice of treatment will depend on the cause and the severity of symptoms. The doctor will explain which treatment options is best for your.
  • For hyperthyroidism treatment options may include, antithyroid medications (medications such as levothyroxine, Liothyronine is also available), radioiodine, and thyroid surgery.
  • Thyroid nodules treatment options may include, watchful waiting, radioiodine, alcohol ablation, surgery and thyroid cancer can be treated mainly by surgery.
  • Treatment of goiter depends on the cause of goiter. If your goiter is caused by not getting enough iodine, you may be given iodine supplement to swallow and T4 supplement. Other options may include radioiodine and surgery.
