Introduction: Morbid obesity is a highly prevalent disease, with bariatric surgery being a fundamental pillar in its treatment.

Objectives: To analyze the results of weight loss at 5 years in patients operated by gastric bypass and sleeve at the Regional University Hospital of Malaga.

Methods: This is a retrospective observational study, where 104 patients with morbid obesity who underwent bariatric surgery at the Regional University Hospital of Malaga between 2011 and March 2017 were analyzed.

Results: The mean age at the intervention was 46.6 years (19-67), 77 women and 27 men, 41 were operated by bypass and 63 by sleeve. The mean baseline weight was 131.1±26.4 kg with a mean BMI of 48.9±7.7 kg/m². 56.8% had a BMI between 40-50 kg/m², 7.8% between 35-40 kg/m², 24.5% between 50-60 kg/m² and 9.8% had a BMI above 60 kg/m². The average weight at one year of the intervention was 86.6 kg, at 2 years 84.8 kg, at 3 years 88.7 kg, at 4 years 91.1 kg, and at the fifth year, the mean weight was 95 kg. The percentages of excess weight lost were also calculated, at one year it was 71.8%, at 2 years it was 73.6%, at 3 years it was 66.4%, at 4 years it was 63.6% and at 5 years it was 59.0%. Likewise, the percentage of patients who had lost more than 50% of the excess weight they had prior to surgery was obtained: at one year it was 88.3%, at 2 years it was 90.0%, at 3 years it was 77.3%, at 4 years it was 78.9% and at 5 years it was 66.3%.

Conclusions: Satisfactory weight results are observed 5 years after bariatric surgery, achieving a loss above 50% of excess weight in 66.3% of patients.
