Diagnosis and Symptoms, Hyperglycemia and DKA
Question from Canonsburg, Pennsylvania, USA:
Why is it that a person with untreated diabetes has to urinate all the time? I think I know the answer but would like someone to verify it. I feel I have a lot of the symptoms and would like to have this answered before I consult my doctor.
Because when the sugar is high (usually above 10mmol/L, 180 mg/dl) it spills into the urine. Unless you can pass sugar lumps, you have to lose water with it.
