Bariatric surgery is an effective weight-loss strategy and often results in remission of type 2 diabetes mellitus (T2DM); still, how this surgery affects T2DM is unknown. A new study suggests that fibroblast growth factor 19 and bile acids are involved in remission of T2DM after bariatric surgery.
Key Points
-
Roux-en-Y gastric bypass (RYGB) leads to weight loss and remission of type 2 diabetes mellitus (T2DM)
-
Levels of bile acids and their intestinal signal, fibroblast growth factor 19 (FGF-19), are increased after RYGB
-
Patients with sustained remission of T2DM after RYGB surgery have the highest increase in serum levels of both FGF-19 and bile acids
-
The bile acid–FGF-19 axis might be an important mechanism by which RYGB improves T2DM
