Yeah, the title says it all.
I feel thirsty a lot of the time and I dunno why. I have 2-3 50 cl water bottles a day, so it's strange to be so thirsty, especially cos it doesn't go away with drinking much. I do have to go to the loo quite a bit cos im drinking a fair amount, and then I have moments where I just feel a bit light-headed and really can't concentrate, they usually last for 20, 30 mins or so then go away.
I don't think I have any other symptoms of diabetes, I don't think I'm always tired and my pee doesn't smell.
So what could it be?
