Cos you have un-diagnosed diabetes?<br />
Update: How much water are you drinking?? If it's allot then that will make you thirsty. As will eating too much salt.
When I was your age I was drinking 2 litre bottles of water allday, it went through me like a siv, If I didn't drink this much then I would be dying of thirst because that is what my body had got used to getting. Try cutting down to a normal level even if you are thirsty.
This woman died because she drank too much water.
maybe you've got diabetes
I drink and drink and I eat but I am pregant so what do I do
Stop drinking the Sodas. They contain lots of bad chemicals and too much sugar. It does sound like diabetes. Do you pee a lot, too?
i don't know if you should increase your water intake as said above, first cut down on your soda intake, if you don't notice a change after that, then yeah increase the water.
Are you super-active? Do you drink things that are diuretic, such as tea, coffee, or alcohol, alot? You may be dehydrating yourself faster than you can hydrate. Try increasing your water uptake. If you're like me and hate regular water, try the bubbly stuff over ice. Or, as has been already suggested, eat water-ba<x>sed fruits and vegetables.
I'm not sure but soda may increase thirst--a little research would probably tell you for positive.
You may have polydipsia (probably spelled wrong lol)
Maybe you're just thirsty for knowledge.
