My seven year old daughter has had some concerning symptoms. She has been drinking to the point that her urine looks like water and she seems like she can't get enough. I asked the pharmacist at cvs and he said to buy the urine glucose strips. I checked her and it came back positive for glucose. Well about six hours later Ichecked again and it was negative. what would cause this? Anyways the thirst just seems to be constant and am not really sure what to do next. I don't want to go rushing to the doctor if it is nothing and end up looking foolish. Any advice or thoughts would be appreciated!
