While an epileptic fit and a hypoglycaemic coma are completely different things, a hypoglycaemic episode can show as a fit / thrashing about / general unco-operativeness.
I trained as a first aider in my teens, nurse in my 20s and joined Territorial Army as a Nursing Officer in late 20s, but could not rejoin when I left to emigrate, then got type 1 diabetes,
A few years ago, travelling on a train between Birmingham and Newcastle upon Tyne, from my seat, I saw some activity in the corridor leading from the dining car - a woman was trying to pour orange juice down into the mouth of a man having a fit, probably confusing epileptic fit and hypoglycaemia. Putting liquid into the mouth of someone who is not fully conscious is dangerous; putting gel into the mouth of a person who is not fully conscious is OK. But, putting anything into the mouth of someone having an epileptic fit is not safe, risking damage to teeth, tongue & mouth of person having the fit and fingers of the person putting them into the mouth. On the train, I stopped the fluid that might have choked him, placed a jacket under his face so it wouldn't get scratched on the doormat, alerted train staff, and man was taken off train by paramedics called to the next station. I also looked for any ID jewellery or card in wallet, that might explain his condition, but there was nothing.
