Glucagon promotes gluconeogenesis (the synthesis of glucose, mainly in the liver) and antagonizes (blocks) the effects of insulin (which pushes sugar into cells). This can lead to hyperglycemia in states of glucagon overproduction, such as in glucagon producing tumors.

∙ 14y agoGlucagon is produced by the pancreas when blood sugar falls too low. It is received by glucagon receptors in the liver, which then trigger the liver to convert stored glycogen to glucose.
All this glucose quickly enters the bloodstream and raises blood sugar. In a normal pancreas, insulin is also produced at the same time (also triggered by the glucagon), which produces insulin to start consuming the glucose. In a diabetic, this insulin may be inadequate or missing.
The phenomenon that overdosing of insulin caused a glucagon release which raised blood sugar higher in diabetics was first published by Dr. Michael Somogyi in 1938 and is still called "Somogyi's Phenomenon" or "Somogyi Rebound".

What hormone reverses hyperglycemia?
Which is the only hormone that can reverse hyperglycemia
Is glucagone an enzyme?
No, glucagon is not an enzyme. Glucagon is a hormone.
What happens if the body produces too much glucagon?
What happens if I have too much glucagon?Rare tumours of the pancreas called glucagonomas can secrete excessive quantities of glucagon. This can cause diabetes mellitus, weight loss, venous thrombosis and a characteristic skin rash. What happens if I have too little glucagon?Unusual cases of deficiency of glucagon secretion have been reported in babies. This results in severely low blood glucose which cannot be controlled without administering glucagon. Glucagon can be given by injection to restore blood glucose lowered by insulin (even in unconscious patients). It can increase glucose release from glycogen stores more than insulin can suppress it. The effect of glucagon is limited, so it is very important to eat a carbohydrate meal once the person has recovered enough to eat safely.
Insulin and glucagon are examples of what type of substances?
insulin and glucagon are examples of what type of substance
What does glucagon do?
from what i know the function of glucagon is to convert glucogen into glucose when there is deficiency of glucose in the body where the glucogen is the access glucose which converted by the insulin
What hormone reverses hyperglycemia?
Which is the only hormone that can reverse hyperglycemia
Why do beta 2 agonists cause hyperglycemia?
It stimulate the β2-adrenoceptors. β2-adrenoceptors normally stimulate hepatic glycogen breakdown (glycogenolysis) and pancreatic release of glucagon, which work together to increase plasma glucose.
Does beta blockers cause hyperglycemia?
beta blocker cause hyperglycemia by inhibiting the glycogenolysis pathway during the energy formation.
Which diuretic drug does not cause hyperglycemia?
Spironolactone
How do exenatides work?
Exenatide mimics incretins, which are hormones that promote the release of insulin from the pancreas when glucose is present. It also lowers the secretion of glucagon during episodes of hyperglycemia.
What are the effects of Glucagon?
Glucagon, a medication sometimes given prior to an upper GI procedure, may cause nausea and dizziness.
What happens if you lack glucagon?
Lacking glucagon is not good for the body and can cause many issues. You could not be able to have kid and have to take pills.
Who is at risk of getting hyperglycemia?
hyPOglycamia not hyperglycemia
Does cyclosporine cause blood sugar changes?
yes it does, it elevate blood sugar causing "hyperglycemia"
What is the icd9 code for hyperglycemia?
code for Hyperglycemia is 790.29
Does hydrochlorothiazide cause hyperglycemia?
The connection between diuretics and hyperglycemia involves intracellular K+ levels. Intracellular K+ is involved in the secretion of a lot of hormones...including insulin. Some diuretics cause hypokalemia, (decrease in K+). This inhibits insulin secretion and can lead to hyperglycemia. It's not really a problem unless the patient is pre-diabetic. In that case, it is significant enough to push them over to diabetes. Hope this helped!
Which hormones cause an increase in blood sugar by converting a carbohydrate stored in the liver into glucose?
Glucagon
