Method of Diagnosing Sarcopenia in Morbidly Obese Patients

Abstract

Introduction. Sarcopenia refers to a clinical syndrome characterized by progressive skeletal muscle disease, loss of muscle mass and strength resulting in impaired physical performance. The prevalence of sarcopenia in the population ranges from 5% to 13% in people aged 43.0 ± 11.1 years and reaches 50% in those over 70. Various methods have been used to diagnose sarcopenia, which, however, have their limitations. Currently, CT scanning is considered the most accurate method for the detection of sarcopenia. Therefore, the development of new methods for early diagnosis of sarcopenia appears relevant. Aim. To investigate different methods of diagnosing sarcopenia in morbidly obese patients. Materials and methods. The study presents an analysis of various methods for diagnostics of sarcopenia in morbidly obese patients, including a patented method based on the research conducted in the BSMU Clinic (Utility Patent No. 2815157 dated 11.03.2024). Results and discussion. Doctors used the suggested method of diagnosis, defined the value of sarcopenia index equal or less than 15, and diagnosed sarcopenia. Conclusion. The prevalence and severity of sarcopenia vary depending on the classification criteria and thresholds used. Since a unified diagnostic method is yet to be developed, it is necessary to continue research into this issue, and introduce sarcopenia detection, prevention, and correction techniques into widespread clinical practice. Indices of sarcopenia and obesity, obtained during an additional preoperative study, provide significant prognostic information superior to body mass index, thereby enabling the direction and scope of surgical interventions to be determined and survival outcomes to be improved.
