Weight loss from bariatric surgery 'can help address premature ageing'

12 July 2016

People who undergo bariatric surgery to lose weight may also be able to address symptoms of premature ageing, according to a new study.

The Medical University of Vienna research assessed 76 overweight patients of an average age of 40, all of whom had been unable to lose weight through lifestyle changes and were referred for bariatric surgery.

One year after surgery, not only had their body mass index reduced by 38 per cent on average, but they also saw decreases in pro-inflammatory cytokines and an increase in a key anti-inflammatory cytokine.

Moreover, two years after surgery the patients had telomeres that were 80 per cent longer than before the procedure. Telomeres function as cellular internal clocks, getting shorter when a cell divides or due to oxidative stress, and represent a key marker of ageing processes.

This is indicative of the positive impact that weight loss surgery can have in terms of reducing unhealthy processes within the body.

Lead author Dr Philipp Hohensinner, a researcher at the Medical University of Vienna, said: "Surgery is the last resort for these patients and it is good to see that not only do they lose weight, but they also reduce the stress on their body and reduce the premature ageing."
