Aim
To investigate long-term effects of sodium-glucose co-transporter 2 inhibitor (SGLT2i) on anthropometric and metabolic factors in Japanese patients with type 2 diabetes (T2DM).
Patients and Methods
This is a retrospective observation study. Forty-six outpatients with T2DM (32 men and 14 women, 51 ± 13 years old, BMI 27.9 ± 4.8, means ± S.D.) who had been treated by SGLT2i for 2 years were selected and their metabolic and anthropometric data were retrieved from medical records retrospectively. Regular instruction for diet and exercise had been performed throughout the administration of SGLT2i in outpatient clinic basis.
Results
By the administration of SGLT2i for 2 years, body weight and body fat amount were significantly reduced (P < 0.0001) in spite of no change in skeletal muscle mass. HbA1c (P < 0.0001), liver function and lipid profile (P < 0.01) were ameliorated and eGFR was reduced significantly (P < 0.0001). It is of note that the reduction of body weight was strongly correlated to that of body fat (r = 0.951, P < 0.0001) with no correlation to the change of skeletal muscle mass. The reduction of HbA1c was strongly correlated to the baseline HbA1c (r = − 0.922, P < 0.0001) and modestly correlated to the baseline eGFR (r = − 0.449, P < 0.01). Multivariate analysis revealed a weak relationship between the amelioration of HbA1c and the reduction of body weight.
Conclusion
SGLT2i can effectively reduce body weight and body fat mass independent of the blood glucose improvement or the renal function. Under the periodical instruction for nutrition and exercise this oral hypoglycemic agent can be safely administered for a long term without a risk for sarcopenia.
