Background: The aim of this study was to evaluate the effect of bariatric surgery on the anthropometric and biochemical parameters of patients.
The effect of surgery on anthropometric parameters like weight, body mass index (BMI), waist circumference, hip circumference, and waist–hip
ratio was studied. The biochemical parameters included glycated hemoglobin A (HbA1c) and lipid profile [serum cholesterol, triglycerides,
high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL)].
Materials and methods: The study was conducted in a tertiary healthcare center in a 1.5-year period on male obese subjects who had undergone
bariatric surgery for morbid obesity. Thorough preoperative evaluation was done by a bariatric team which included the bariatric surgeon,
dietician, endocrinologist, chest physician, anesthesiologist, and cardiologist. A total of 17 patients who underwent surgery for morbid obesity
and gave consent were included in the study and were followed up for 3 months thereafter.
Results: Significant weight loss along with a significant decrease in BMI, waist circumference, hip circumference, and waist–hip ratio was
observed at 4 weeks and 3 months after bariatric surgery. A statistically significant difference was seen in the fall in HbA1c levels. There was a
significant effect on serum cholesterol, serum triglycerides, and serum HDL and LDL levels. No statistically significant difference was seen in
serum VLDL levels.
Conclusion: Significant weight loss after bariatric surgery in men results in improved clinical outcomes. Lipid profile and glycemic control also
improved in patients over follow-up time. The improvement in metabolic parameters may serve as motivators for obese men considering surgery.
