Weight loss after gastric bypass surgery is a gradual process.
Patients who have gastric bypass surgery start to see results within a few weeks of surgery as the restrictive and malabsoptive methods of gastric bypass promote rapid weight loss.
As the body adjusts to consuming fewer calories, weight loss slows but continues as long as patients maintain the correct diet.
Within 6 months of surgery patients will notice significant weight loss and most patients loose 50% of excess weight within the first 6 months post-gastric bypass.
One year post-surgery patients can see the complete results of weight loss surgery and many patients loose up to 80% of excess body fat.
