I am trying to work out why I can never get my glucose under 5. Apparently cortisol decreases the effectiveness of insulin. So if your cortisol is high you will be more insulin insensitive. The weird thing is that my blood cortisol is high. But siliva was low. Im still waiting for my transcortin results.
Insulin
Cortisol counteracts insulin, contributes to hyperglycemia-causing hepatic gluconeogenesis[10] and inhibits the peripheral utilization of glucose (insulin resistance) [10] by decreasing the translocation of glucose transporters (especially GLUT4) to the cell membrane.[11][12] However, cortisol increases glycogen synthesis (glycogenesis) in the liver.[13] The permissive effect of cortisol on insulin action in liver glycogenesis is observed in hepatocyte culture in the laboratory, although the mechanism for this is unknown.
Gastric and renal secretion
Cortisol stimulates gastric-acid secretion.[18] Cortisolās only direct effect on the hydrogen ion excretion of the kidneys is to stimulate the excretion of ammonium ions by deactivating the renal glutaminase enzyme.[19] Net chloride secretion in the intestines is inversely decreased by cortisol in vitro (methylprednisolone).[20]
My cells should be very insulin sensitive as I exercise 2 times a day. It is know that low cortisol can cause digestion issues.
So one thing indicates high cortisol another thing indicates low cortisol.
