  • Familial Disorders (inherited genetic disorder)
  • Nodules which have formed on the Thyroid Gland

Exposure to Radiation

Exposure to Radiation at a young age from dental x-rays, other forms of x-rays are the main causes in Australia of radiation exposure which can affect the function of the thyroid gland.

  • Ten times more women than men worldwide will be diagnosed with some form of thyroid disorder.
  • Thyroid disorders, especially hypothyroidism - or an underactive thyroid, becomes more common as we grow older.  
  • Iodine Deficiency has re-emerged in Australia and we can expect more people to suffer from swelling and enlargement of the thyroid gland, also know as a 'Goitre'. 
  • Statistics show 1 million Australians have an undiagnosed thyroid disorder.
