CSENDES J, Attila et al. Results of gastric bypass for morbid obesity after a follow up of seven to 10 years. Rev. méd. Chile [online]. 2011, vol.139, n.11, pp. 1414-1420. ISSN 0034-9887. doi: 10.4067/S0034-98872011001100004.
weight and complications of obesity, seven to 10 years after gastric bypass surgery. Material and Methods: One hundred eighteen subjects with morbid obesity, aged 15 to 66years (103 women), were followed for a mean of 94 months after surgery. Body weight, fasting blood glucose, total cholesterol, triglycerides and hemoglobin were measured before surgery and during follow up. Results: At 24 months of follow up, all patients lost weight and there was a mild weight increase at 94 months, that paralleled the preo-perative body mass index. Diabetes, hypercholesterolemia and hypertriglyceridemia subsided in 95, 87 and 94% of cases, respectively. Twenty percent of patients had mild anemia and 11% moderate or severe anemia. No patient recovered the preoperative weight. Conclusions: Weight reducing effects of gastric bypass are maintained after 94 months of follow up with the expected health benefits.
