In search of the mechanisms of hypoglycaemia after bariatric surgery 

Bariatric (weight-reducing) surgery is a recognized treatment option for obesity. A previously underestimated and potentially serious consequence of bariatric surgery is the occurrence of hypoglycemia after ingestion of meals (so-called postprandial hypoglycaemia). The aim of this research project is to better understand the causes and effects of postprandial hypoglycemia. The project is conducted in close collaboration with national and international experts and implements state-of-the-art techniques to study metabolism (e.g. metabolic imaging with stable isotopes and mathematical modelling of sugar metabolism). The findings will be used to better understand and treat postprandial hypoglycaemia.
