1- Polyuria (Excessive Urination)
Polyuria is defined as an increase in the frequency of urination. When you have abnormally high levels of sugar in your blood, your kidneys draw in water from your tissues to dilute that sugar, so that your body can get rid of it through the urine. The cells are also pumping water into the bloodstream to help flush out sugar, and the kidneys are unable to reabsorb this fluid during filtering, which results in excess urination.
To meet the clinical definition of polyuria, urine output for an adult must exceed 2.5 liters per day (normal urine output is 1.5 liters per day).
As it’s pretty hard for you to measure this yourself, simply note if you’re visiting the restroom far more often than usual and/if you’re staying there longer when you do.
