Bariatric surgery may trump non-surgical techniques in helping people lose weight, the Los Angeles Times reports. The article cites a study published in BMJ that followed patients with a body mass index greater than 30 who either underwent bariatric surgery or attempted non-surgical weight loss for a minimum of 6 months and up to 2 years. Researchers “reported on body weight, cardiovascular risk factors, quality of life, or adverse events” in both groups. Results showed that, on average, bariatric patients lost 57 more pounds than non-surgical patients and were also 22 times more likely to see remission of their type 2 diabetes and 2 1/2 times more likely to see improvement in metabolic syndrome. Additionally, surgical patients were more likely to report improved quality of life. Despite these positive findings, surgical patients were more likely to develop pneumonia, depression, or anemia. Although these surgeries are pricey, healthcare providers speculate that they surgeries will increase in number in the upcoming years.
