Morbid obesity has a direct impact on the development of cardiovascular disease. One-anastomosis gastric bypass (OAGB) is an effective surgical technique for the control of body weight and the reduction of cardiovascular risk. This work examines the change in weight loss, lipid profile and cardiovascular risk in 100 patients (71 women, 29 men), mean age 42.61 ± 11.33 years at 3, 6, 9, 12, 18 and 24 months after OAGB. At 24 months post-surgery, mean body weight was significantly reduced compared to pre-operative values (116.75 ± 22.19 kg vs. 69.66 ± 13.07 kg), as were mean total cholesterol (201.86 ± 44.60 mg/dL vs. 172.99 ± 32.26 mg/dL), LDL (Low-Density Lipoprotein) cholesterol (126.90 ± 39.81 mg/dL vs. 96.28 ± 26.99 mg/dL), triglycerides (138.05 ± 78.45 mg/dL vs. 76.04 ± 30.34 mg/dL) and cardiovascular risk (total cholesterol/HDL (High-Density Lipoprotein) cholesterol: 4.32 ± 1.24 vs. 2.93 ± 0.71), while the mean HDL cholesterol concentration was significantly higher (49.09 ± 14.16 mg/dL vs. 61.98 ± 14.86 mg/dL) (all p < 0.001). In conclusion, OAGB surgery led to significant reductions in body weight, a significant improvement in the lipid profile, and a reduction in cardiovascular risk.
