Insulinoma In Children
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
Insulinoma: 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 (low blood glucose levels). ...Read more
Please go to the "U.S. National Library of Medicine" or "MedlinePlus" and search for Insulinoma.
You will find all of the information you should need.
More than 90% of insulinomas are not cancerous. ...Read more
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
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. These tumors are very rare, often hard to find, and you should go to a specialized center for surgery. ...Read more
Insulinoma- I have being dignose in the university of miami with insulinoma, but can't find location. Move to houston tx need a referal.?
Endocrinologist: You need an endocrinologist for starters. You may wish to start with baylor or ut houston, unless you have a good relationship with someone else. ...Read more
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
Non-fasted insulin 59 when b/s is 86, and in the 18 when b/s 68, 12 when b/s Is 53. High enough to suggest insulinoma? Or congenital hyperinsulintima
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
It's cancer!: Any type of cancer can understandably cause anxiety and fear within patients and their loved ones. The prognosis of insulinoma depends on the stage at which it was diagnosed, and how it is responding to therapy. Surgery can often be curative, but if discovered in a later stage, it can be very difficult to treat. ...Read more
Yes, but....: They are quite rare.Get a more detailed answer ›
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
What can cause high insulin with low blood sugar? Besides insulinomas? 54-69 blood sugar 11-22 insulin when low.
Not much: Really besides insulinomas (which are exceptionally rare, so rare that even the largest of academic instutions have seen a large number of these cases) and people accidentally or purposefully administering too much insulin. But to be able to better interpret the data you provided, more information around the circumstances when these numbers were acquired is necessary. ...Read more
With an insulinoma how low do blood sugars have to fall between meals? Mine fall to 3.0 - 3.4 (55-65). Insulinoma?
They Don't Have Too: What you are describing is more consistent with reactive hypoglycemia, it is a bit more controversial and does not have set dx criteria. It is more a clinical dx based on the doctors eval, labs as support & tx response helpful. An insulinoma is very diff and has more strict criteria for presumptive dx inc a FASTING BS<40, with innap insulin, c-peptide, pro insulin levels & other lab tests. ...Read more
Ate lunch sugar around 100, went out to build snowman with daughter, felt horrible after 15 min., went in, sugar 45. Scared if insulinoma.
Low risk: If you had a normal sugar (100) and this happened after a meal and some work, it is more likely something in your meal triggered excessive Insulin release. Work with your doc to sort this out. The condition reactive hypoglycemia is a real one and much more common than an insulinoma. ...Read more
Ate lunch, went out to build snowman with daughter, felt horrible, came in sugar 45. Scared to death of insulinoma. Had cptide a year ago negative.
Insulinoma or Cyst?: These are 2 different entities. Cysts are typically fluid filled benign growths that rarely require any intervention unless they are growing. Insulinoma is more serious as it is a solid tumor/growth which produces excess of Insulin which can cause serious problems due to low blood sugar levels (hypoglycemia). So try to find out which of these two diagnoses you likely have. Good luck. ...Read more
