According to The American Thyroid Association (ATA), 20 million Americans have some form of thyroid disease. What’s more, 60 percent of those with thyroid disease are unaware of their condition.  

Check out these fascinating facts to learn more about the Thyroid gland and how it affects your health. 

The Thyroid gland 

  • Location: The thyroid gland is a butterfly-shaped organ situated at the bottom of the throat.  
  • Function: It produces hormones that help regulate metabolism, heart rate and body temperature.  
  • Hormones:  
  • Triiodothyronine (T3)  
  • Thyroxine (T4) 
  • Calcitonin (produced by C-cells of the thyroid gland) 

The thyroid gland produces these hormones from iodine and tyrosine. Iodine is an element found in certain foods; tyrosine is an amino acid found in proteins.  

  • Regulation: The pituitary gland (in your brain) regulates the production of hormones by sending out thyroid-stimulating hormone (TSH). 


Thyroid disorders include: 

  • Goiter (enlargement of the thyroid gland) 
  • Hyperthyroidism (when your thyroid gland makes more hormones than your body needs) 
  • Hypothyroidism (when your thyroid gland does not make enough hormones) 
  • Thyroid cancer 
  • Thyroid nodules (lumps in the thyroid) 
  • Thyroiditis (inflammation and swelling of the thyroid) 


Are you at risk? 

Women are five times more likely to be diagnosed with a thyroid condition than men. 

You have a higher chance of developing thyroid disease if you: 

  • Are a female. 
  • Are older than 60 (especially women). 
  • Have a family history of thyroid disease. 
  • Have a medical condition (like pernicious anemia, type 1 diabetes, rheumatoid arthritis, primary adrenal insufficiency, lupus, and Sjögren’s syndrome). 
  • Take medications that are high in iodine (amiodarone). 
  • Have had treatment for a thyroid condition or cancer (thyroidectomy or radiation). 

Common symptoms of thyroid disease 

Thyroid diseases can be divided into two broad groups —
