Question

Why diabetic patients urinat more?

Answer 1

Excessive thirst (also called polydipsia) and increased urination (also known as polyuria) are classic diabetes symptoms.
When you have diabetes, excess sugar (glucose) builds up in your blood. Your kidneys are forced to work overtime to filter and absorb the excess sugar. If your kidneys can't keep up, the excess sugar is excreted into your urine, dragging along fluids from your tissues. This triggers more frequent urination, which may leave you dehydrated. As you drink more fluids to quench your thirst, you'll urinate even more.
