Take part in a survey about treatments for hyperthyroidism Hyperthyroidism (or overactive thyroid) affects up to 3% of the UK population. Current treatment options include: antithyroid drugs, radioactive iodine (RAI) and surgery. We are working with a team of researchers based at Newcastle University who would like to understand more about patients’ understanding and experiences of RAI and surgery as treatment options and which of the treatments may offer better outcomes with regard to long term health. If you have been treated for hyperthyroidism please help us plan this important research study by completing this short survey. It should only take you 5-10 minutes to complete and all responses will be anonymous.
