Polyuria is the most common diabetes symptom – how to spot

As polyuria is driven by an increase in blood glucose, this sign can also crop up once you’re diagnosed with the blood sugar condition.

Once your blood glucose becomes too high, your body will try to remedy the situation by removing it from the blood through your kidneys. 

“When this happens, the kidneys will also filter out more water and you will need to urinate more than usual as a result,” Diabetes.co.uk states.

While polyuria is one of the most “common” symptoms of diabetes, it isn’t the only red flag.
