Hyperthyroidism

Hyperthyroidism, often called overactive thyroid, is a condition caused by too much thyroid hormone. Thyroid hormone comes from the thyroid gland, a small, butterfly-shaped gland in the front of your neck.

Thyroid hormone affects many things in your body, including how your body uses energy. Too much thyroid hormone can make you feel anxious, warm, sweaty, and feel your heart beating.

The most common cause of hyperthyroidism is called Graves’ disease.

Hyperthyroidism symptoms

  • Anxiety
  • Feeling jittery and shaky
  • Palpitations (feeling your heart beating)
  • Enlarged thyroid gland in the neck (goiter)
  • Sweating more than usual
  • Frequent bowel movements
  • Insomnia

How can I get help for hyperthyroidism?

See your primary care doctor if you have hyperthyroidism symptoms. If you have hyperthyroidism, your doctor will refer you to an endocrinologist, a hormone specialist.

To diagnose you, your doctor will perform a physical exam and order blood tests. The most common blood test is called “thyroid stimulating hormone (TSH).” People with hyperthyroidism typically have an abnormally low TSH level. TSH usually goes the opposite direction to thyroid hormone (when thyroid hormone levels are high, TSH is usually low).
