Pancreatic polypeptide, pancreatic glucagon and enteroglucagon in morbid obesity and following gastric bypass operation.
The influence of morbid obesity and gastric bypass operation on pancreatic polypeptide (PP), pancreatic glucagon and enteroglucagon was studied in six morbidly obese patients before and 6-9 months after surgery. Hormone plasma levels were determined in the fasting state and after a standardized test meal. Fasting levels of PP, pancreatic glucagon and enteroglucagon were not significantly different between the pre- and post-operative state as well as compared to normal controls. The postprandial response showed a significant reduction of PP, a significant increase of enteroglucagon and no change of pancreatic glucagon after surgery compared with the preoperative values.
