Sarcopenia is common in older men and women, and yet awareness of its clinical relevance is still relatively low. Only formally included in the International Classification of Diseases in 2016, the condition may impact societies with serious health-related and financial consequences unless consistent, effective methods of identification and management are adopted.

This second edition of Sarcopenia provides geriatricians and other healthcare professionals with a revised and expanded examination of this understudied and underdiagnosed condition. Edited by two leading authorities on the subject, it covers the epidemiology and diagnosis of sarcopenia, as well as treatment options and possible prevention strategies. Eight newly written chapters build upon existing knowledge with fresh data on topics including sarcopenia's biomarkers and its impact on the healthcare economy. This important text:

Defines sarcopenia and explains its clinical relevance
Covers all recent scientific evidence
Outlines treatment options
Considers prevention strategies
Discusses sarcopenia as a public health priority
Features eight new chapters covering topics such as sarcopenia's clinical management, its biomarkers, and its financial impact
Containing vital information for clinicians and other professionals working in geriatric care, nursing homes, nutrition, cancer, endocrinology, surgery, sports medicine and many other specialties, Sarcopenia, second edition, is a groundbreaking and essential new resource.
