Background: Sarcopenia refers to the progressive and generalized loss of skeletal muscle mass, strength, and function and is associated with falls, fractures, hospitalization, and even mortality. Owing to rapid population aging, the prevalence of sarcopenia is expected to increase, and this condition is increasingly gaining attention as an important topic in research and clinical settings. This review focuses on the diagnosis, pathophysiology, and management of sarcopenia. Current Concepts: Diagnosis of sarcopenia can be confirmed based on low muscle mass accompanied by low muscle strength, or low physical performance. The European Working Group on Sarcopenia in Older People and the Asian Working Group for Sarcopenia guidelines are commonly used in clinical practice. Intrinsic factors associated with skeletal muscles, such as inflammation, anabolic resistance, mitochondria, and neuromuscular junctions, combined with extrinsic factors associated with the systemic environment, including decreased endocrine function, malnutrition, and immobilization all play a role in impaired muscle anabolism, muscle atrophy, and weakness. Currently, the Food and Drug Administration has not approved any specific medications for treatment of sarcopenia. Therefore, non-pharmacological interventions such as aerobic, resistance, and combined exercise and appropriate nutrition (protein and essential amino acids) are important for prevention and treatment of sarcopenia. Discussion and Conclusion: Sarcopenia is a manageable target for improvement of overall health outcomes. Exercise and nutrition are essential components of nonpharmacological management of sarcopenia. Future studies are needed to identify early diagnostic biomarkers and pharmacologic targets and to develop consistent pre-emptive management strategies and sensitive measures to predict effectiveness of sarcopenia management and treatment response.
