Learn More about Hyperthyroidism

What is hyperthyroidism?

Hyperthyroidism is a condition in which the thyroid gland becomes overactive. When overactive, the thyroid gland produces levels of T4 and T3 that are higher than necessary in the body. This can lead to a rapid heart rate and the development of other common symptoms of the disease. While hyperthyroidism can be successfully treated with medication, it is important to note that it can result in serious complications if left undiagnosed and untreated.

Currently, it’s estimated that 1.2% of the population in the United State has hyperthyroidism, according to the National Institute of Diabetes and Digestive and Kidney Diseases. Anyone can develop hyperthyroidism. However, women are two to ten times more likely than men to develop hyperthyroidism. Additionally, pregnant women and their babies are at greater risk for complications from hyperthyroidism if it is not well controlled.

What are the risk factors of hyperthyroidism?

Groups at greater risk factor for hyperthyroidism include:

  • Women

  • People with a family history

  • People with a personal history of chronic diseases such a type 1 diabetes

What are the symptoms of hyperthyroidism?

There are various symptoms of hyperthyroidism. Some of the most common, according to the Mayo Clinic, are:

  • Weight loss

  • Rapid heart rate

  • Irregular heartbeat

  • Nervousness, anxiety, and irritability

  • Tremors

  • Sweating and increased sensitivity to heat

  • Changes in menstrual patterns

  • Changes in bowel patterns

  • Enlarged thyroid gland

  • Fatigue or muse weakness

  • Difficulty sleeping

However, it is important to note that in some cases there may not be any signs or symptoms. Also, these symptoms may indicate a separate health condition. Therefore, be sure to contact your medical provider for assistance with a diagnosis.

Who should get tested for hyperthyroidism?

If you have symptoms of hyperthyroidism or have had a TSH (Thyroid-Stimulating Hormone) screening that indicated a low TSH, a T3 screening may be right for you.

How is hyperthyroidism diagnosed?

Hyperthyroidism is diagnosed through the combination of a physical exam from a doctor and laboratory testing. A TSH screening and T3 are typically both used to confirm a diagnosis.


If the results from a T3, Free test are high, it may indicate an underactive thyroid and the presence of hypothyroidism. If the results from the screening are low, then it may indicate an overactive thyroid and the presence of hyperthyroidism. In most cases, T3 test results are best evaluated when the test is completed in conjunction with other thyroid tests such as the TSH and T4, Free screenings.

Once your results are available, you may share these results with your medical provider for assistance with interpretation and for guidance as to additional testing and/or to develop a treatment plan based on your results. If monitoring your current thyroid condition, your medical provider can also use your test results to assess the success of your current treatment plan.

How is hyperthyroidism treated?

There are several treatments for hyperthyroidism. To determine the best treatment plan for you, speak with your medical provider. He or she can best evaluate your condition and discuss with you available treatment options. Possible treatments for hyperthyroidism include anti-thyroid drugs, radioactive iodine, beta-blockers, and surgery.
