The weight loss that follows a successful bariatric surgery makes most patients feel younger. But a new study suggests that following bariatric surgery, some patients show signs of being biologically younger, as well.
At Stanford University, researchers looked for evidence of change in bariatric surgery patients by measuring their telomeres — regions of repeating DNA sequences at the end of a chromosome that grow a little shorter with age and chronic illness. Telomeres are considered a biomarker of the aging process.
In a group of 51 patients, the latest study found that 12 months after bariatric surgery, telomeres lengthened significantly in those who had the highest pre-surgery levels of LDL cholesterol–a robust predictor of heart disease risk–and in those with the highest pre-surgery levels of C-reactive protein–a sign of inflammation throughout the body.
The new research was presented Friday in Atlanta, at the annual meeting of the American Society for Metabolic and Bariatric Surgery. The lead author of the study–which is considered preliminary since it has not yet been published–is Dr. John Morton, a professor of surgery at Stanford University Medical Center. Morton is president-elect of the profession society for weight-loss surgeons.
