Background:
Obesity contributes to a chronic disease with lethal complications. Leptin as an adiponectin interacts with fat metabolism. Surgical extra fat resection is an interventional approach to control obesity. We aimed to evaluate how body contouring surgery would influence on leptin plasma level.
Methods:
Females candidate for body contouring surgery were allocated in to two groups included abdominal wall liposuction alone and in combination with abdominoplasty from 2018 to 2020. Demographic data was registered. Serum plasma level of leptin with the ELISA method was measured on the day before the operation and also after 3, 6, and 12 months after surgery with 8 h fasting prior to blood sampling. Finally the amounts of resected fat, type of surgical approach, and plasma level of leptin were analyzed.
Results:
Total 124 females with mean age of 37 ± 10.1 years underwent abdominal wall liposuction (58%) and liposuction + abdominoplasty (42%) respectively. Mean weight and BMI significantly decreased postoperatively for both groups (p < 0.01). Although in both groups leptin concentration was higher in all triple blood sampling following operation in compared to preoperative measurement, changes were not significantly considerable (p = 0.6). Coefficient of correlation between amounts of resected fat and plasma level of leptin was directly positive and calculated 0.4 (p = 0.03).
Conclusion:
Leptin interacts independently from abdominal wall contouring surgery. However it could be a marker for amounts of resected fat after operation.
