(SAN FRANCISCO) -- A new study published in the Archives of Surgery suggests that gastric bypass surgery is more effective than the lap band in helping morbidly obese people lose weight.
Researchers at the University of California in San Francisco studied 200 patients, 100 of whom chose to undergo gastric bypass and 100 who opted for a lap band. The study found that after a year, those who had a gastric bypass lost an average of 64 percent of their excess weight, compared to 36 percent for those with a lap band.
Gastric bypass was also more effective in the resolution of diabetes, at 76 percent, compared to the lap band, at 50 percent.
However, experts have cautioned about the validity of the results, given that it can take up to three years to see the full effect of lap band surgery.
