What is hyperthyroidism?

Hyperthyroidism is a condition in which the thyroid gland, located at the base of the neck, produces excessive amounts of the hormone thyroxine. An overactive thyroid gland can cause such symptoms as irritability, rapid heartbeat, excessive sweating, weight loss, and sleep problems.

How does a doctor diagnose hyperthyroidism?

To get diagnosed with hyperthyroidism an individual must visit a doctor to get a blood test. Through this test, a diagnosis will show how much thyroxine and TSH is found in the person’s blood. If a person has too much thyroxine or low levels of TSH, this is a strong signal that they have hyperthyroidism. Other ways a doctor will diagnose hyperthyroidism is by completing a physical exam. The thyroid gland is located in the neck, and the doctor will see if it’s swollen or tender. At this point, if the doctor feels the patient has hyperthyroidism, they will likely proceed with a radioiodine uptake test or a thyroid scan. These two tests may be used together to explore the entire thyroid gland.

What are the typical treatments for hyperthyroidism?

Several medications can be prescribed to individuals with an overactive thyroid. One of the safest treatments is radioactive iodine taken orally. Other anti-thyroid medications, such as methimazole or propylthiouracil, may be necessary. But these drugs come with dangerous side effects and should be used with caution. Beta blockers can help treat symptoms related to hyperthyroid, such as heart palpitations.

Do I need to have surgery to treat hyperthyroidism?

Individuals who are not able to take anti-thyroid medications, or who aren’t interested in radioactive iodine therapy, surgery is an option. Women who are pregnant will typically turn to surgery in place of taking the medications for hyperthyroid while pregnant. The surgical procedure is called a thyroidectomy. This treatment involves a removal of the majority of the thyroid gland. If an individual has a thyroidectomy, they will have to take medications that mimic thyroid hormone for the rest of their life. While surgery is not the primary treatment for hyperthyroidism, it is a permanent solution for individuals who don’t want to take risky anti-thyroid medication.
