Learn the tools for addressing a widespread public health issue with this practical guide
Iron deficiency and iron overload are among the most common health conditions encountered in the course of clinical practice, with the potential to produce a range of morbidities and increase overall mortality. However, these conditions are often under-recognized, resulting in unnecessary disease and loss of well-being. There is an urgent need to raise awareness among clinicians of the causes, effects and management of iron imbalance.
Iron in Clinical Practice meets this need with a brisk, practical guide to recognizing and treating both iron deficiency and iron overload in clinical settings. Edited by two Oxford haematologists and leading specialists in iron management, it covers major areas of medicine and surgery impacted by these disorders. The result is an essential resource for both beginning and experienced clinicians.
Iron in Clinical Practice readers will find: - Introductory chapters outlining the role of iron in the body, its utilization and mechanisms of trafficking and distribution, and how these are impacted by disease.
- Coverage of a range of clinical settings across medicine, surgery and primary care.
- Illustrations, tables, and graphs throughout.
Iron in Clinical Practice is ideal for all health care practitioners of any specialty.
