I always take it to mean 'where you have required someone else's help', as a regular hypo where you shake a bit for 10 mins whilst eating glucose tablets is hardly an insurance risk. In this particular case, it means 'have you needed professional treatment for a hypo?'
In essence, they are looking for ways to get out of paying. If you answer 'no' to their question and then require hospital treatment for a hypo the first thing they'll do when they get the bill is examine your medical records. If you have not had medical treatment for hypo in the last 12 months you are in the clear. That's my take on it anyway.
