Summary

Adiposity is associated with prediabetes and type 2 diabetes. In very severe cases of adiposity in combination with type 2 diabetes, bariatric surgery has proven to be a successful therapy option. So far the molecular mechanisms that lead to an improvement of type 2 diabetes after bariatric surgery are not fully understood. It is planned to characterize the metabolic and neuroendocrine changes in subjects before and after bariatric surgery. One special focus of the study is brain insulin resistance, a condition known to be associated with obesity with impact on the brain and whole body metabolism.
