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.

Insulin is the hormone that reverses hyperglycemia by promoting the uptake and storage of glucose in cells, especially in the liver, muscle, and adipose tissue. Insulin helps lower blood sugar levels by facilitating the conversion of glucose into glycogen for storage or into energy for immediate use.
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.
No, glucagon is not an enzyme. Glucagon is a hormone.
The alpha cells of the pancreas are the source of release glucagon.
The alpha cells in the pancreas produce glucagon. Glucagon is a hormone that works in opposition to insulin to regulate blood sugar levels by stimulating the liver to release glucose into the bloodstream.
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.
Glucocorticoids cause hyperglycemia by increasing the production of glucose in the liver and reducing the uptake of glucose by cells in the body.
beta blocker cause hyperglycemia by inhibiting the glycogenolysis pathway during the energy formation.
Spironolactone

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.
Glucagon, a medication sometimes given prior to an upper GI procedure, may cause nausea and dizziness.
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.

yes it does, it elevate blood sugar causing "hyperglycemia"
code for Hyperglycemia is 790.29
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!
