Our expert says:
Hyperinsulinemia is an abnormally high level of insulin in the bloodstream. Chronic hyperinsulinemia is most often caused by insulin resistance, a condition in which the body cannot use insulin properly. Insulin is a hormone necessary to move glucose (blood sugar) from the bloodstream into the cells for use as energy. Insulin resistance is a feature of metabolic syndrome and type 2 diabetes.
Hyperinsulinemia may also be due to a tumor of the pancreas (insulinoma). Hyperinsulinemia in infants and children may be due to genetic defects or to diabetes in the mother during fetal development.
Other causes of and contributors to hyperinsulinemia include:
Impaired liver function
Pregnancy or breastfeeding
Polycystic ovarian syndrome
Short-term hyperinsulinemia may be due to an overdosage of insulin medication, unusual physical exertion or a large carbohydrate load that requires extra insulin to process.
As the above indicates, hyperinsulinaemia can be a complicated condition, and, although the most common cause is related to dietary and weight issues, it is important to exclude all other potentailly organic causes.
Whether the high insulin levels are causing the stiffness is questionable, however this will be bourne out if the stiffness improves / disappears as the insuulin levels decrease with appropriate management.
