What does insulinoma mean?

Key points. Insulinomas are tumors in your pancreas. They make extra insulin, more than your body can use. Insulinomas can cause hypoglycemia, or low blood sugar.

Which effect do counter regulatory hormones have on insulin?

Counterregulatory hormones have the opposite effect of insulin: they increase blood glucose levels. They do this by increasing the release of glucose that is stored in the liver, reducing the uptake of glucose by muscle cells, and making cells resistant to insulin.

What is IAS disease?

Insulin autoimmune syndrome (IAS) is a rare condition, characterized by spontaneous episodes of hyperinsulinemic hypoglycemia due to the presence of high serum concentrations of insulin autoantibodies (IAA).
