Background and Aim
Obesity is one of the greatest public health concerns worldwide. Weight loss surgeries have been increased in recent decades due to the world’s epidemic of obesity. The aim of this prospective study is investigating metabolic factors of morbid obese patients following Roux-en-Y gastric bypass surgery.
Methods
This was a nonrandomized prospective cohort study conducted from 2010 to 2013 on 60 consecutive patients who had body mass index (BMI) of more than 40 kg/m2 and met the surgical indication criteria of bariatric surgery. Upon discharge, patients were followed in outpatient clinic of Qaem Hospital, Mashhad, Iran, each 3 months for 12 months. Measurement of anthropometric and metabolic indices was done in each postoperative visit.
Results
Mean BMI reduction was 15.26 ± 3.45 kg/m2 in the patients with an average value of 28.84 ± 3.94 (range from 22 to 40 kg/m2), which was significantly lower than the base value (p < 0.001). After a 12-month follow up, patients had lower low-density lipoprotein, triglycerides, and total cholesterol (p < 0.001 for all the variables), while achieving a greater high-density lipoprotein (p = 0.004). An improvement was seen in all of hypertensive patients after a 3-month follow up and blood pressure remained within normal limit in further follow ups. Complete remission was observed in all the patients with obstructive sleep apnea.
Conclusion
It appears reasonable that multidisciplinary treatment including surgical alternatives should be concerned for all morbidly obese patients, considering high rate of failure of conservative medical therapy in this setting.
