| Abstract | ||
| Background: Body mass index (BMI) is widely used to assess eligibility for bariatric surgery, but it does not accurately reflect body fat or muscle distribution. Bioelectrical impedance analysis (BIA) offers more detailed body composition data, potentially improving candidate selection and postoperative monitoring. Objective: To compare BMI and body composition measurements in patients undergoing bariatric surgery and assess their roles in surgical decision-making and postoperative follow-up. Patients and Methods: This prospective study included 50 morbidly obese patients undergoing bariatric procedures at Cairo University Hospitals. All participants were assessed pre- and three months postoperatively using both BMI and BIA-derived body composition parameters, including body fat percentage and muscle mass. Results: Bariatric surgery led to significant reductions in BMI and body fat percentage, with no significant changes in muscle percentage postoperatively. Both BMI and body composition assessments were similarly effective in determining surgical eligibility; however, BIA was more informative for postoperative follow-up, as some patients exhibited greater muscle loss than fat loss. Conclusion: While BMI and body composition analysis are both useful in assessing bariatric surgery candidates, BIA provides superior insight during postoperative follow-up, highlighting the need for individualized nutritional monitoring. | ||
