Insulinoma (Definition)

An insulinoma is a tumor of the pancreas that secretes insulin. The beta cells in the pancrease (pancrelipase) secrete Insulin in response to high glucose levels in the blood. Since an insulinoma is a collection of abnormal cells, an insulinoma will produce Insulin regardless of the blood glucose levels and can cause profound hypoglycemia ...Read more

Hypoglycemia: Insulinoma is extremely rare, but usually not a hard diagnosis to make once it is suspected. The blood sugar and insulin levels must be done fasting. Post prandial testing and glucose tolerance tests are worthless in making this diagnosis. You should see an endocrinologist. ...Read more

Are there treatment guidelines for insulinoma?

Yes: First is appropriate diagnosis. Make sure that the patient's blood sugar is repaetedly low and that they are not taking Insulin or other drugs. Next, scans may be useful for localizing the tumor. Only then - an experienced endocrine (or hepatopancreatobiliary) surgeon should remove it.

How should I be expected to fast for 8 hours to do lab work if i could possibly have insulinoma? I don't understand how considering the circumstances

Opposite effect: I don't really know what is being tested but the problem with insulinomas are actually the drop in blood sugar after eating. The rise in blood sugar after eating causes the production and release of too much Insulin as a response to the rise in blood sugar. After fasting, the proinsulin, c peptide, blood sugar is tested and correlated and imaging may be done if suspected. ...Read more

Could an insulinoma be used to cure diabetes?

Could an insulinoma be used to cure diabetes?

Won't work: Insulinomas are cruel tumors that are usually semi-malignant and pump insulin into the bloodstream, sickenng the person and forcing them to overeat. If a savvy physician makes the call, they can often be cured surgically. In type I diabetes, immunity destroys the normal islets and would destroy an insulinoma. In type II, one's resistant to insulin. Glad your own endocrine tumor was R'd. Good luck ...Read more

How could we defferentiate between hypoglycemia caused by factitious insulin injection and by an insulinoma?

How could we defferentiate between hypoglycemia caused by factitious insulin injection and by an insulinoma?

Cpeptide test: A fasting C-peptide test could help, but isn't always definitive. A C-peptide test measures native Insulin production and isn't elevated by outside Insulin (injected insulin). So a low or normal level when fasting would be evidence against an insulinoma (insulin tumor). An elevated C-peptide when fasting shows elevated Insulin levels when they shouldn't be, as could happen with an insulinoma ...Read more
