Hyperinsulinemia: Overview

Hyperinsulinemia refers to having a high level of insulin in the blood stream. It is also called simply “high blood insulin”. This is typical in the most common form of Type 2 Diabetes, where insulin resistance causes the body’s muscle cells to become resistant to the use of insulin, and the body actually produces more insulin to compensate. Although many people assume that insulin would be low in diabetes, this is mainly true of Type 1 Diabetes (Juvenile Diabetes), but the opposite is actually common in Type 2 Diabetes. Testing of insulin levels in the blood is a relatively simple blood test. This blood test can be useful as part of the diagnosis of Type 2 diabetes, as it can help confirm the correct subtype of diabetes. The opposite result of “low blood insulin” is more likely in Type 1 Diabetes, although there are less common insulin-deficient subtypes of Type 2 Diabetes as well. There are also other less common causes of hyperinsulinemia, such as an insulinoma.
