A 37-year-old member asked:

Can you tell me is glucagon or insulin secreted by the pancreas during the fight or flight response?

Glucagon not insulin: The "fight or flight" response is related to secreting adrenaline. Adrenaline can increase glucagon levels, causing blood sugars to rise. Insulin levels do not rise with adrenaline.
Dr. Hratch Karamanoukian

Glucagon and insulin: Glucagon will increase available sugar in the bloodstream and would be more useful during the "fight" part of the response. Insulin is secreted when there is excess in the bloodstream, e.g. as you eat a meal or after eating, during the relaxations phase "flight" part.

No : Hi. No, they don't really play a role in the fight or flight response. Epinephrine from the adrenal medulla can cause glycogenolysis at the liver just like glucagon can, and epi is flooding the system...don't need glucagon. Insulin is present, but is an anabolic hormone, and the fight or flight response is all about catabolism...insulin in very low levels works fine. Good endocrine physiology!
