Sarcopenic obesity refers to the combination of obesity and low muscle mass or strength in older adults, which increases the risk of adverse health outcomes. This condition is characterized by a decline in muscle strength and mass, often due to factors such as excess energy intake, physical inactivity, low-grade inflammation, insulin resistance, and hormonal changes. While muscle mass was traditionally considered the primary indicator of sarcopenia, recent research emphasizes the importance of muscle strength as a better predictor of functional limitations and mortality in older adults. The term "sarcopenic obesity" is being re-evaluated due to the complexity of defining and measuring the condition. The development of sarcopenic obesity is influenced by age-related changes in body composition, including increased fat mass and decreased muscle mass and strength. Physical inactivity, inflammation, and hormonal imbalances contribute to muscle impairment. Insulin resistance, which is common in obesity, further exacerbates muscle dysfunction. Growth hormone and testosterone levels are also affected, contributing to muscle loss. Malnutrition and weight loss can worsen muscle mass and strength, particularly in older adults. Studies have shown that sarcopenic obesity is associated with increased disability, reduced functional capacity, and higher mortality risk. Obesity and low muscle strength are often linked, with obese individuals more likely to have low muscle strength. The combined effects of obesity and muscle impairment significantly increase the risk of health complications. Research highlights the need for better definitions and more comprehensive terminology to accurately describe this condition. Future studies should focus on identifying effective prevention and treatment strategies, particularly in older adults. The interplay between obesity and muscle impairment is complex, and further research is needed to fully understand the mechanisms and consequences of sarcopenic obesity.Sarcopenic obesity refers to the combination of obesity and low muscle mass or strength in older adults, which increases the risk of adverse health outcomes.
