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 ...
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.
Hyperproinsulinemia is a disease where insulin is not sufficiently processed before secretion [1] and immature forms of insulin make up the majority of circulating insulin immunoreactivity in both fasting and glucose-stimulated conditions (insulin immunoreactivity refers to all molecules detectable by an insulin antibody, i.e. insulin, proinsulin, and proinsulin-like material).
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.

Type 2 diabetes is characterized by high blood glucose in the context of insulin resistance and relative insulin deficiency. [70] This is in contrast to type 1 diabetes in which there is an absolute insulin deficiency due to destruction of islet cells in the pancreas and gestational diabetes that is a new onset of high blood sugars associated ...
Hyperglycemia or hyperglycaemia is the situation in which blood glucose level is higher than in a healthy subject. A fasting healthy human shows blood glucose level up to 5.6 mmol/L (100 mg/dL). After a meal (postprandial) containing carbohydrates, healthy subjects show postpandrial euglycemic peaks of less than 140 mg/dL (7.8 mmol/L).
Detectable amounts of insulin are abnormal and indicate that hyperinsulinism is likely to be the cause. Other aspects of the person's metabolic state, especially low levels of free fatty acids, beta-hydroxybutyrate and ketones, and either high or low levels of C-peptide and proinsulin can provide confirmation.
