Off-bike hydration

So assuming you are treating your diabetes correctly....then what would cure dehydration as opposed to ingesting lots of water? I am not quite understanding this.
Are you suggesting some sort of sports drink would solve dehydration better than water?
If you are so dehydrated that you have a headache and drinking lots of water won't solve it for you, then I think this is something aside from ordinary dehydration and should be taken seriously. perhaps the headache is somehow related to sugar levels rather than dehydration?
