Thyroid Disease

Thyroid disease can cause too much or too little thyroid hormone caused by either an overactive or underactive thyroid. The thyroid gland is located in the front of the neck, just below the voice box, and it produces the hormones that help the body control metabolism, and can affect your heart rate, blood pressure, body temperature and weight.

There are four main types of thyroid disease:

  • Hyperthyroidism – too much thyroid hormone
  • Hypothyroidism – too little thyroid hormone
  • Benign (non-cancerous) thyroid disease
  • Thyroid cancer
