I have repeatedly speculated that GR may be a factor for the Reactive hypoglycaemics amongst us.
Since glucagon ‘switches off’ (acts as a balancing antagonist to insulin), if an RHer has ‘an overshoot’ of insulin, resulting in a hypo, then what was the glucagon doing? Off washing its hair? Painting its toenails?
Could be G insufficiency, or G resistance.
Resistance is possible to just about anything - drugs, herbs, hormones - and if one thing goes out of wack, then the whole system can get off kilter too, in an endless vicious circle of coping mechanisms, like a row of dominoes.
Of course testing my personal Glucagon Resistance theory is nothing more than a pipe dream.
