I hope you dont believe this sense unless your a diabetic has no bearing on either. Infact it can help to take insulin to release your pancreas from undue strees and keep your hemaglobin down.
UH?
GH is a counterregulatory hormone to insulin. Hyperinsulinism (causing hypoglycemia) will cause GH secretion. Injecting exogenous insulin to the point of hypoglycemia will cause secretion of endogenous GH. This endogenous GH will inhibit the ability of insulin to stimulate uptake of glucose in peripheral tissues and enhance glucose synthesis in the liver, thus helping to increase blood glucose. This is also why you see a pardoxical increase in endogenous insulin after injecting exogenous growth hormone. The body is again trying to regulate blood glucose levels at all costs.
Taking exogenous insulin has absolutely NO PROVEN "release of stress" effects on the pancreas that I'm aware of. This is an internet bullshit rumor that seems to be gaining in popularity. If anything exogenous insulin in a nondiabetic may actually increase pancreatic Islet cell stress by stimulating insulin secretion because of counterregulatory hormones secreted by the body causing insulin insensitivity.
You want to decrease stress on your pancreas? DON'T EAT SHIT PROCESSED HIGH SUGAR, HIGH FRUCTOSE CORN SYRUP FOOD!!! Thats the simplest way to decrease stress on your pancreas.
And decreasing hemoglobin? What are you talking about with that? Did you mean hemoglobin A1C and have a typo? A nondiabetic will have no appreciable change in hemoglobin A1C values after injection of exogenous insulin because of insulin counterregulatory hormones. Its a finely tuned balance that should be functioning normally in a nondiabetic.
