More Statistics on Bariatric Weight Loss SurgeryAccording to official statistical estimates, obesity is set to become the leading cause of mortality in the United States by 2005, with a death toll of 500,000 per year. As a result, medical experts are increasingly turning to surgical intervention as a method of obesity treatment. Here are more statistics on such bariatric procedures. Statistics on Weight Loss after SurgeryWeight loss usually reaches a maximum between 18 and 24 months after bariatric surgery. Average excess weight loss at five years is 48-74 percent after gastric bypass and 50-60 percent after vertical banded gastroplasty. In a statistical review of over 600 bariatric patients following gastric bypass, with 96 percent follow-up, mean excess weight loss still exceeds 50 percent at fourteen years. Another 10 year follow-up series from the University of Virginia reports weight loss of 60 percent of excess weight at 5 years and in the mid 50's between years 6 and 10. Similar statistical surveys have shown similar weight loss results. Statistics on Weight Loss Without SurgeryStatistical reports show that non-surgical methods alone have not been effective in achieving a medically significant long term weight loss in severely obese adults. The majority of patients typically regain all the weight lost over the next five years. The average medical weight reduction trial is a 10-12 week study with average weight loss of 2.5 kg.
