Effects of Empagliflozin on Sarcopenia Risk, Body Composition, and Muscle Strength in Type 2 Diabetes: A 24-Week Real-World Observational Study
Abstract
Background and Objectives: Sodium-glucose cotransporter 2 (SGLT2) inhibitors are increasingly used in type 2 diabetes (T2D) due to their cardiorenal benefits and weight-lowering effects. However, concerns have emerged regarding their potential adverse impact on lean mass and muscle strength particularly in patients at risk for sarcopenia. This study aimed to evaluate the effects of empagliflozin on skeletal muscle mass. Secondary objectives were to assess changes in glycemic control, body weight, fat mass and handgrip strength. Materials and Methods: In this 24-week real-world observational study, 31 adult patients with T2D were assigned to either empagliflozin or non-SGLT2i treatment groups. Patients did not receive a high-protein diet, a resistance exercise program or any other weight-reducing medications such as glucagon-like peptide-1 (GLP-1)-based therapies. Anthropometric measurements, body composition via bioelectrical impedance analysis (BIA), and handgrip strength testing were performed at baseline and after 6 months. Sarcopenia was defined according to EWGSOP2 criteria. Results: The empagliflozin group showed significant improvements in HbA1c, fasting plasma glucose, body weight, waist circumference, and fat mass (p < 0.05 for all). No significant changes were observed in the empagliflozin group after 6 months in appendicular skeletal muscle mass index (from 7.81 ± 1.33 kg/m2 to 7.84 ± 1.38 kg/m2, p = 0.154). No statistically significant changes were observed in…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 31 participants or records.
