Bariatric Surgery, Obesity, Sarcopenia
Conditions
Brief summary
This prospective observational study aims to evaluate longitudinal changes in sarcopenia-related parameters in patients undergoing bariatric surgery. Obesity and rapid weight loss following bariatric surgery may lead to changes in muscle mass, muscle strength, and physical performance, which are important components of sarcopenia. Participants will be evaluated before bariatric surgery and during postoperative follow-up visits. Muscle thickness will be assessed using ultrasonography of the femoral muscles. Muscle strength and physical performance will be evaluated using handgrip strength, the 5-meter walk test, and the five-times sit-to-stand test. The study aims to investigate the effects of bariatric surgery on muscle function and physical performance over time and to contribute to the early identification of sarcopenia risk in this patient population.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Femoral Muscle Thickness | Preoperative baseline, postoperative 1st month, 3rd month, 6th month, and 12th month assessments | Femoral muscle thickness will be assessed using ultrasonography before bariatric surgery and during postoperative follow-up visits to evaluate longitudinal changes associated with sarcopenia. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Handgrip Strength | Preoperative baseline, postoperative 1st month, 3rd month, 6th month, and 12th month assessments | Handgrip strength will be evaluated before bariatric surgery and during postoperative follow-up visits to assess changes in muscle strength. |
| Change in Five-Times Sit-to-Stand Test Performance | Preoperative baseline, postoperative 1st month, 3rd month, 6th month, and 12th month assessments | Functional lower extremity performance will be evaluated using the five-times sit-to-stand test before bariatric surgery and during postoperative follow-up visits. |
