Sarcopenia and type 2 diabetes (T2DM) are two age-related diseases that are common in the elderly and have a significant impact on their health and quality of life. Sarcopenia is characterized by the progressive loss of muscle mass, strength, and function, while T2DM is a chronic disease marked by elevated blood sugar levels. The coexistence of these two conditions is concerning, as individuals with T2DM are at higher risk of developing sarcopenia due to factors such as insulin resistance, chronic inflammation, and reduced physical activity. Conversely, sarcopenia can worsen T2DM by impairing blood sugar control and increasing the risk of complications. Effective treatment strategies for sarcopenia in elderly patients with T2DM include physical exercise, a balanced diet rich in protein and nutrients, and pharmacological therapies. Exercise, particularly resistance training, is crucial for maintaining muscle mass and strength. A diet high in protein, essential amino acids, vitamin D, calcium, and omega-3 fatty acids can help improve muscle function and reduce inflammation. Antidiabetic drugs should be selected carefully, as some may contribute to muscle loss. The pathogenesis of sarcopenia in T2DM involves insulin resistance, hyperglycemia, oxidative stress, and chronic inflammation. These factors impair muscle function and lead to muscle loss. Early detection and comprehensive treatment are essential to improve muscle function and overall health outcomes in elderly patients with T2DM and sarcopenia. This review highlights the importance of early intervention and the need for a multidisciplinary approach to manage these conditions effectively.Sarcopenia and type 2 diabetes (T2DM) are two age-related diseases that are common in the elderly and have a significant impact on their health and quality of life.
