Glucagon is a hormone that rapidly counters the metabolic effects of insulin in the liver, causing glycogenolysis and release of glucose into the blood. It can raise the glucose by 30–100 mg/dL within minutes in any form of hypoglycemia caused by insulin excess (including all types of diabetic hypoglycemia).
Insulin self-injected for treatment of diabetes (i.e., diabetic hypoglycemia) Insulin self-injected surreptitiously (e.g., Munchausen syndrome) Insulin self-injected in a suicide attempt or fatality; Various forms of diagnostic challenge or "tolerance tests" Insulin tolerance test for pituitary or adrenergic response assessment; Protein challenge
When individuals take insulin without needing it, to purposefully induce hypoglycemia, this is referred to as surreptitious insulin use or factitious hypoglycemia. [ 3 ] [ 2 ] [ 24 ] Some people may use insulin to induce weight loss, whereas for others this may be due to malingering or factitious disorder , which is a psychiatric disorder . [ 24 ]
Ketotic hypoglycemia classically presents in male young children, typically between the ages of 10 months and 6 years, in the morning after a prolonged overnight fast. Symptoms include those of neuroglycopenia, ketosis, or both. [6] [7] Neuroglycopenic symptoms usually include lethargy and malaise, but may include unresponsiveness or seizures.
In normal children and adults, insulin secretion should be minimal when blood glucose levels fall below 70 mg/dL (3.9 mM). There are many forms of hyperinsulinemic hypoglycemia caused by various types of insulin excess. Some of those that occur in infants and young children are termed congenital hyperinsulinism.
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.

Symptomatic hypoglycemia caused by insulin was first recognized in 1922 when one of the first diabetes patients ever treated with insulin was found "climbing the walls" due to hypoglycemia induced by insulin. The first description of children with congenital hyperinsulinism was made in 1954 by Dr Irvin McQuarrie in his presidential address to ...
