Completely coincidentally my docs last week texted me and said your latest blood test indicates pre-diabetes. This was really annoying as my 'latest' blood test is a year ago and they've just texted me 
I normally get a bit shaky and 'hangry' if I don't eat regularly but on Thursday I had a full on hypoglycaemic attack (never had it before) I had:
Boiling hot/sweating profusely/heart palpitations (completely terrifying) starvation, weakness, shaking
Unfortunately I was in a meeting and couldn't leave to get food so I basically thought I was going to die for about 35 minutes
I've never been so scared or so unwell 
When I left the meeting I ate cheese and a protein bar (had sugar in it too) but I didn't feel right for an hour
I'm completely baffled by this as I've only had symptoms since losing nearly 5 stone - I'm now 'just' overweight and continuing to lose weight easily
Anyone have any thoughts?
