Effects of Gamitaeeumjowee-tang for Weight Loss in Overweight and Obese Shift Workers: A Retrospective Chart Review

Objectives : This study aimed to evaluate the weight loss effects and safety of Gamitaeeumjowee-tang in overweight and obese shift workers through a retrospective chart review.Methods : A total of 27 shift workers with a body mass index (BMI) ≥23 kg/m² who visited a Korean medicine obesity clinic for weight loss were included. Participants took Gamitaeeumjowee-tang for 12 weeks. Changes in body weight, body composition, blood pressure, and adverse events were assessed and compared with a control group of 33 non-shift workers.Results : After 12 weeks of treatment, the shift worker group showed a significant reduction in body weight (6.63±3.37 kg, P<0.05), body fat mass (6.13±2.96 kg, P<0.05), BMI (2.52±1.28 kg/m², P<0.05), and body fat rate (5.23 ± 3.18%p, P<0.05) along with a significant increase in skeletal muscle rate (2.92 ± 1.74%p, P<0.05). There were no significant differences in weight loss and body composition changes between the shift worker group and the non-shift worker group. When evaluating changes in blood pressure and pulse, only systolic blood pressure significantly decreased in the shift worker group (P=0.041). Most adverse events were mild, and no serious adverse reactions were reported.Conclusions : Gamitaeeumjowee-tang appears to be a safe and effective option for weight management in overweight and obese shift workers without causing serious adverse events.
