Hypoglycaemia: Insulin is a stress hormone
There is an additional twist to the hypoglycaemic tale which complicates the situation further. When one becomes stressed for whatever reason, one releases stress hormones in order to allow one to cope with that stress.
Insulin is such a stress hormone and has the effect of shunting sugar in the blood stream into cells. This produces a drop in blood sugar levels and also causes hypoglycaemia.
Therefore, hypoglycaemia can be both a cause of stress and the result of stress, indeed, another one of those vicious cycles that are so often seen in disease states.
