  • Overactive Thyroid

  • Thyrotoxicosis

What is Hyperthyroidism?

Hyperthyroidism happens when your thyroid gland makes too much thyroid hormone. The thyroid is a small, butterfly-shaped gland in the front of your neck. These hormones control your energy use. When there is too much, your body speeds up too fast.

What are Common Symptoms of Hyperthyroidism?

  • Losing weight without trying

  • Fast or uneven heartbeat

  • Feeling nervous or shaky

  • Sweating a lot or not liking heat

  • Bigger appetite but still losing weight

  • Trouble sleeping

  • Loose stools more often

  • Tired muscles or weakness

What are Causes of Hyperthyroidism?

The top cause is Graves' disease. That is when your body's defenses attack the thyroid and make it overwork. Other reasons include lumps in the thyroid, swelling that releases stored hormones, too much iodine, or some medicines.

How is it Diagnosed?

Doctors use blood tests to check hormone levels. TSH is typically low, while T4 or T3 are high. They might test for antibodies as well. Ultrasounds or scans are often used to check for physical lumps or nodules.

How is it Treated?

  • Medicines: Drugs like methimazole to block thyroid hormone production.

  • Radioactive iodine: To shrink the gland and reduce hormone output.

  • Beta-blockers: To ease a fast heartbeat and tremors.

  • Surgery: To remove part or all of the thyroid gland.

  • Follow-up: Most people need lifelong check-ups. After treatment, you might need thyroid replacement pills for the rest of your life.

Trends (USA)

  • Prevalence: About 1% of Americans have it (around 3 million people).

  • Demographics: Women are diagnosed 5-10 times more often than men.

  • Aging: Risk increases significantly after age 60.

  • Projections: A small rise is expected over the next 5 years due to an aging population and improved diagnostic testing.

History

Doctors identified the thyroid in the 1600s. In 1835, the condition was linked to Graves' disease. Surgical interventions began in the late 1800s, while antithyroid drugs and radioactive treatments were introduced in the 1940s. Blood testing became significantly more accurate in the 1970s, leading to more precise care.
