Hyperthyroidism is a condition where the thyroid gland produces more thyroid hormones than are needed by the body. It is also referred to as thyrotoxicosis, or an overactive thyroid. It can occur if you have: 

  • Graves’ disease
  • A toxic multinodular goitre
  • A solitary toxic thyroid adenoma (an adenoma is a clump of cells)
  • Thyroiditis (inflammation of the thyroid gland) which is temporary

Being diagnosed with hyperthyroidism or Graves' disease can be distressing and isolating. Please see our resources for further information and support.
