Background: Sarcopenia is a disorder that progressively reduces muscle mass, function, and strength. It is a serious health issue for the elderly that can affect everyday tasks, raise the risk of falls, and cause disability. However, emerging evidence highlights its prevalence among middle-aged adults, underscoring the need for early identification and intervention. Aim: This literature review explores the multifaceted aspects of sarcopenia in middle-aged adults, including its prevalence, nutritional correlates, diagnostic criteria, and management strategies. Methods: A comprehensive literature search was conducted using databases such as Google Scholar, Research Gate, PubMed, and Medline. Inclusion criteria encompassed research articles, systematic reviews, clinical trials, observational studies, and case studies focusing on Sarcopenia. Results: Sarcopenia, a multifactorial geriatric condition, is increasingly recognized as a global health concern. Management combines resistance training, protein-rich diets, and emerging pharmacological agents, but challenges like inconsistent diagnostic criteria, financial barriers, and limited research necessitate region-specific guidelines and multidisciplinary strategies to support healthy aging worldwide. Conclusion: Treating sarcopenia includes specialized exercise routines, dietary plans, pharmacological therapy, and management. Addressing current obstacles requires creating region-specific recommendations. Multidisciplinary cooperation and ongoing research can improve management and prevention.
