Thyroid problems are notoriously difficult to diagnose and many people suffer for years, undergoing treatments for the symptoms rather than the underlying problem. Based on many years' experience in this complex field, the author describes the practical ways in which sufferers can help themselves.

Thyroid problems affect an estimated one in three of the adult population, yet they are difficult to diagnose on the basis of blood tests and often go undiagnosed for many year. This is the second, greatly updated and revised, edition of Dr Durrant-Peatfield's practical guide to recognizing the signs and symptoms of thyroid disease and to treating the problem with diet and natural supplements, in conjunction with modern western drugs and surgery when really necessary.
