2. Increased Urination

Excessive urine production is medically known as polyuria, which is normally characterized by a urine output that exceeds the three liters per day in adults. This increase in urine volume generally results in an increased frequency of urination. Polyuria is a possible symptom of prediabetes and diabetes; however, it can also be seen in many other medical conditions (i.e. diabetes insipidus).

In general, the blood in our body is filtered by the kidneys. Normally, the glucose that is filtered by the organ is later reabsorbed into our blood almost entirely; thus, there should be little to no glucose in our urine. In prediabetes or diabetes, the high levels of glucose in the blood surpass the ability of the kidney to reabsorb it. As a result, glucose is excreted in the urine (glucosuria) and, because it causes water retention in the tubule of the kidney, it increases the amount of urine that is produced (osmotic diuresis). Additionally, recall that in these conditions there is an increased sensation of thirst (due to hyperglycemia) that can lead to excessive fluid intake and increased urination.
