[Adipositas - new aspects in internistic care before and after bariatric surgery].

Indication for bariatric or metabolic surgery depends primarily on body mass index. Recent study results however suggest, that other markers are more reliable predictors of metabolic success. A revision of indication criteria is therefore necessary especially for surgical therapy of type 2 diabetes mellitus. Postoperative management should include screening for postbariatric hypoglycemia and bone density. Furthermore psychologic surveillance is recommended.
