I had neuroendocrine tumor evaluation, is it affected by an increase in pancreatic polypeptides?

I’m just wanting to know if a carbohydrate meal would increase pancreatic polypeptide release. I had this test done as part of a neuroendocrine tumor evaluation and the result was very high. I read online it should be done fasting but my doctor disagreed, and said only protein and exercise would change the result, not carbohydrates, however she is not a neuroendocrinologist. I called the office of a neuroendocrinologist to schedule a 2nd opinion and the nurse said the test has to be done completely fasting, and won’t even schedule the consult until I have it done fasting, so I don’t know what to think. The level was 2000 and this was about 20 minutes after eating a high carbohydrate meal, but no protein. I also have diabetes which is not perfectly controlled.

Technically carbs won’t, Protein intake will in fact increase pancreatic polypeptide secretion. To ensure test results, fasting is recommended.

Fasting is the correct preparation for the test.

Hi and welcome to question doctors.com
Of course you have to do the test with complete fasting…
