Hyperinsulinemia is a condition in which there are excess levels of insulin circulating in the blood relative to the level of glucose. While it is often mistaken for diabetes or hyperglycaemia, hyperinsulinemia can result from a variety of metabolic diseases and conditions, as well as non-nutritive sugars in the diet.
Insulin levels above 3 μU/mL are inappropriate when the glucose level is below 50 mg/dL (2.8 mM), and may indicate hyperinsulinism as the cause of the hypoglycemia. The treatment of this form of hyperinsulinism depends on the cause and the severity of the hyperinsulinism, and may include surgical removal of the source of insulin, or a drug ...
Insulin resistance leads to hyperinsulinemia which, in turn, leads to an excess production of androgen hormones by the ovaries. High levels of androgen hormones (hyperandrogenism) in females causes excessive hair growth, acne and irregular menstruation. Patients with both underlying mechanisms of insulin resistance may have more severe ...
Slightly elevated levels are classified as prediabetes, a precursor to type 2 diabetes. ... Also, some causes of insulin resistance, like pregnancy, are temporary. ... There are some signs of ...
The dispersal of luteinized theca cells throughout the ovarian stroma—in contrast to their distribution in PCOS, in which luteinized theca cells occur around cystic follicles only—causes women with hyperthecosis to have higher testosterone levels and virilization than women with PCOS. Elevated insulin is also characteristic of hyperthecosis ...
Elevated insulin levels have been helpful to predict response to medication and may indicate women needing higher doses of metformin or the use of a second medication to significantly lower insulin levels. Elevated blood sugar and insulin values do not predict who responds to an insulin-lowering medication, low-glycemic diet, and exercise. Many ...
A dysfunctional HPA-axis causes high cortisol levels to circulate, which results in raising glucose and insulin levels, which in turn cause insulin-mediated effects on adipose tissue, ultimately promoting visceral adiposity, insulin resistance, dyslipidemia and hypertension, with direct effects on the bone, causing "low turnover" osteoporosis.

In insulin-deficient diabetes (exogenous) insulin levels do not decrease as glucose levels fall, and the combination of deficient glucagon and epinephrine responses causes defective glucose counterregulation. Furthermore, reduced sympathoadrenal responses can cause hypoglycemia unawareness.
