Austrian researchers have uncovered short- and long-term metabolomics changes in blood samples from a subset of individuals who have undergone bariatric surgery for weight loss.

Using unbiased metabolomic profiling, the team tested blood samples from Roux-en-Y gastric bypass surgery patients in Austria and Switzerland, including two dozen individuals who had type 2 diabetes prior to surgery. The investigators identified metabolomic shifts in samples collected before the bariatric surgery, just a few weeks post-surgery, and roughly a year later.
