  Since each person can experience the feelings of low blood glucose differently, there are a variety of symptoms that can be associated with a low. These signs and symptoms of a dropping blood glucose level can develop quickly. […] These symptoms are caused by the release of the fight-or-flight hormone called epinephrine (adrenaline).

• #1 What Is Hypoglycemia? (for Teens) | Nemours KidsHealth

  https://kidshealth.org/en/teens/hypoglycemia.html

  Hypoglycemia happens when a person’s blood sugar levels are abnormally low, and it’s a potentially serious condition. […] Some symptoms of hypoglycemia are caused when the body releases extra adrenaline (epinephrine), a hormone that raises blood sugar levels, into the bloodstream to protect against hypoglycemia. High blood levels of adrenaline can make the skin become pale and sweaty, and a person can also have symptoms such as shakiness, anxiety, and heart palpitations (a fast, pounding heartbeat). […] Other symptoms of hypoglycemia are caused when not enough glucose gets to the brain; in fact, the brain is the organ that suffers most significantly and most rapidly when there’s a drop in blood sugar. These symptoms include headache, extreme hunger, blurry or double vision, fatigue, and weakness. At its most severe, insufficient glucose flow to the brain can cause confusion, seizures, and loss of consciousness (coma).

  Hypoglycemia unawareness is when you do not have the early symptoms of low blood glucose. Being unaware of low blood glucose is a common occurrence, especially in people who have had type 1 diabetes for more than 5 to 10 years, and it can be dangerous.

  There is no agreed-upon lab value that defines hypoglycemia. Hypoglycemia is said to be present when the patient has symptoms consistent with hypoglycemia in addition to a low serum glucose measurement (less than 70 mg/dL). […] Typically, neurogenic and neuroglycopenic symptoms of hypoglycemia occur at a glucose level of or below 50 to 55 mg/dL, but this threshold can vary from individual to individual. […] Patients who have diabetes can present with symptoms of hypoglycemia at relatively higher serum glucose levels. Chronic hyperglycemia alters the „set point” in which neuroglycopenic/neurogenic symptoms become apparent. […] Severe insulin reactions may be fatal, so it is essential to contact EMS immediately when an individual is disoriented or unconscious. […] Non-diabetic individuals who show signs or symptoms of hypoglycemia should contact their clinician to evaluate their situation further. Severe or prolonged hypoglycemia can be life-threatening, and in patients with diabetes, there is a correlation with increased mortality.

  https://www.health.harvard.edu/a_to_z/hypoglycemia-a-to-z

  Hypoglycemia is an abnormally low level of blood sugar (blood glucose). Hypoglycemia triggers the release of body hormones, such as epinephrine (adrenaline) and norepinephrine (noradrenaline), which serve to raise the low sugar level. The release of these hormones causes the early symptoms of hypoglycemia such as tremor, sweating, rapid heartbeat, and anxiety. […] Because the brain depends on blood sugar as its primary source of energy, if untreated hypoglycemia may interfere with the brain’s ability to function properly, resulting in blurred vision, difficulty concentrating, and even loss of consciousness and convulsions (seizures). […] Hypoglycemia can cause: […] Symptoms related to the brain „starving” for sugar: Headache, dizziness, blurred vision, difficulty concentrating, poor coordination, confusion, weakness or fainting, tingling sensations in the lips or hands, confused speech, abnormal behavior, convulsions, loss of consciousness, coma.

This condition typically arises from abnormalities in the mechanisms involved in glucose homeostasis. The glucose level at which an individual becomes symptomatic is highly variable (threshold generally at 50 mg/dL). […] Neurogenic or neuroglycopenic symptoms of hypoglycemia may be categorized as follows: Neurogenic (adrenergic) (sympathoadrenal activation) symptoms: Sweating, shakiness, tachycardia, anxiety, and a sensation of hunger.

[…] The symptoms of Whipple’s triad have been used to describe hypoglycemia since 1938. For Whipple’s triad, the practitioner must first recognize symptoms of hypoglycemia, then obtain low blood glucose, and finally, demonstrate immediate relief of symptoms by correcting the low blood glucose with glucose treatment. […] The clinical manifestations of hypoglycemia can be classified as either neuroglycopenic or neurogenic. Neuroglycopenic signs and symptoms are signs and symptoms that result from direct central nervous system (CNS) deprivation of glucose.
