Thyroid UK supports people who have undiagnosed thyroid disease by educating them about thyroid disease and related disorders, informing them about thyroid testing to aid in their diagnosis and also about good nutrition to enable good thyroid health. We also help people to learn about treatment options (up to 16% of people do not do well on the preferred treatment given by the NHS) once they have been diagnosed as well as help them to find their optimum levels of thyroid hormone. Undiagnosed hypothyroidism and incorrect treatment can be a barrier to taking part fully in work and family life.
