title: [Results of gastric bypass for morbid obesity after a follow up of seven to 10 years].
abstract: BACKGROUND
  There is a paucity of information about the long term effects of gastric bypass for morbid obesity.
  
  
  OBJECTIVE
  To study the evolution of weight and complications of obesity, seven to 10 years after gastric bypass surgery.
  
  
  METHODS
  One hundred eighteen subjects with morbid obesity, aged 15 to 66 years (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 preoperative 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.
