Insulinoma (Pancreas Tumor)
Overview
Insulinoma is a neuroendocrine tumor of the pancreas that results in the production of excessive insulin.

Definition ...
Insulinoma: A tumor that forms in cells that make insulin. Insulin is a hormone that controls the amount of glucose (sugar) in the blood. It moves glucose into the cells, where it can be used by the body for energy.

Insulinoma
A tumor of the beta cells in areas of the pancreas called the islets of Langerhans. Although not usually cancerous, such tumors may cause the body to make extra insulin and may lead to a blood glucose (sugar) level that is too low.
Insulinoma. This type of tumor produces too much insulin, resulting in hypoglycemia (low blood sugar). An insulinoma is more likely to be benign; only 10% become malignant.
insulinoma - a rare pancreatic tumor that secretes insulin, the hormone that lowers glucose levels in the blood.
Insulinoma
A rare type of tumour of the pancreas. Insulinomas make abnormal amounts of insulin and release it into the blood.

Insulinomas release insulin, which can cause low blood sugar, leading to weakness and dizziness.
Somatostatinomas secrete somatostatin, which can result in diarrhoea.
VIPomas release VIP, leading to diarrhoea and high blood pressure.
An insulinoma is treated with surgery to remove the tumor. Hypoglycemia caused by problems with the adrenal or pituitary glands is treated by replacing the missing hormones with medication.

Risk: Insulinomas occur in all age groups, although they occur most commonly between the ages of 40 and 60 (Tran 199). The median age at diagnosis is usually 47 years (Siperstein).
Abnormally high amounts of C-peptide warn of the possible presence of a tumor called an insulinoma that secretes insulin. Normal levels of C-peptide may signal that all is well.

Autoantigens include glutamic acid decarboxylase, insulin, insulinoma-associated protein, and other proteins in β cells.
Most neuroendocrine tumours are malignant, except insulinoma. They commonly spread to the lymph nodes and the liver. Some other uncommon sites of distant spread include the bone, lung, brain and other organs.
Certain kinds of tumors, affecting the pancreas (insulinomas)
After stomach surgery
People with kidney failure, who are on dialysis, may experience hypoglycemia.
If you have liver disease, you may be at risk for hypoglycemia.
Islet cell tumors include insulinomas, glucagonomas, and gastrinomas (Zollinger-Ellison syndrome). A family history of multiple endocrine neoplasia, type I (MEN I) is a risk factor for the development of islet cell tumors.

In the pancreas: the different types of pancreatic NETs are named according to the hormone they produce. For example, insulinomas produce too much insulin and gastrinomas produce too much gastrin (a hormone that stimulates stomach acid secretion).
For example, cells in the pancreas that make insulin or glucagon can become cancerous ('insulinomas' and 'glucagonomas'). These behave differently to ductal adenocarcinoma.

A fasting glucose level below 40 mg/dL (2.2 mmol/L) in women or below 50 mg/dL (2.8 mmol/L) in men that is accompanied by symptoms of hypoglycemia may mean you have an insulinoma, a tumor that produces abnormally high amounts of insulin.
Insulinoma - a tumour of the pancreas that triggers the overproduction of insulin.
Liver failure - loss of the liver's capacity to produce glucose can cause hypoglycaemia.

Excessive insulin production with hypoglycaemia, hunger, jitteriness, tachycardia, and flushing occurring in conditions such as functional disorders of the pancreas, hyperplasia of the islets of Langerhans, or insulinoma.

A rare tumor of the pancreas (insulinoma) may cause overproduction of insulin, resulting in hypoglycemia. Other tumors may result in excessive production of insulin-like substances. Or, the tumors themselves may use up too much glucose.
An excessively high blood insulin level (hyperinsulinemia) may be caused by a rare disorder of the beta cells in your pancreas, where insulin is released. One such disorder is a beta cell tumor, called insulinoma.
