What are hyperglycemic hormones?

Hint: Hormones are your body's chemical messengers. Hormone travels in our bloodstream to the tissues or organs. They work slowly, over time, and affect many various processes, including: Growth and development. Metabolism – it means how our body gets energy from the foods which we eat.

Complete answer:
Pancreatic glucagon, the hyperglycemic hormone secreted by the alpha cells of the islets of Langerhans, promotes glycogenolysis, neoglucogenesis, lipolysis, and ketogenesis.
Glucagon, a peptide hormone secreted by the alpha cells of pancreas, when the blood sugar concentration falls. The foremost important function of glucagon is to extend the blood sugar concentration, So glucagon is taken into account as a hyperglycemic hormone.
Epinephrine-induced hyperglycemia is markedly accentuated by concomitant elevations of glucagon and cortisol or in patients with diabetes. In both cases, the effect of epinephrine on hepatic glucose production is converted from a transient to a sustained response, thereby accounting for the exaggerated hyperglycemia.
Other common diseases and disorders related to the pancreas are: Hyperglycemia: This condition is caused by abnormally high blood sugar levels. It is often caused by overproduction of the hormone glucagon.
Hormones like the expansion hormone, glucagon, cortisol and catecholamines, can cause hyperglycemia once they are present within the body in excess amounts.

Note:
Glucagon is named hyperglycemic hormone. Glucagon causes glycogenolysis (i.e. breakdown of glycogen into glucose) and gluconeogenesis (i.e. synthesis of glucose from non-carbohydrates). It also reduces the cellular glucose uptake and utilisation. This leads to a rise within the blood sugar level.
