I don't know what she eats now, but there were references to glucose tablets which I assume also means insulin which seems quite unusual for a T2 diabetic diagnosed only two years ago.
Something doesn't seem to quite stack up - the comment on the illness and letting blood sugar get out of control through fasting - for one - fasting goes the other way. So that sounds like a person who has been recommended to eat carbs put on an insulin regime to do so, then having failed to eat carbs by inadvertent fasting whilst busy, suffered incidents of hypoglcaemia having not taken enough glucose tablets to offset the insulin.
My understanding was that for most of us insulin is much more likely to be later in the process and certainly not before diet and metformin have failed which I would expect takes a while to find out ? ?
To be honest, it wouldn't surprise me to find she is getting " special" i.e. accelerated treatment because of her position - if so its just as likely to be making things worse rather than better - I'm no expert but sometimes being treated as special can have its downsides!
I just hope she gets the advice she needs to control it properly.
High profile sufferers have so much potential to pave the way for treatment regimes to change compared to normal mortals because they have a audience.
