Frequent urination is a common symptom of diabetes. It occurs due to how the body handles excess sugar, affecting the kidneys, fluid balance, and overall hydration levels. Tap to read!

Hyperglycemia

When blood sugar levels are high, the excess glucose is tried to be flushed out through urine production.

Renal Filtration

Kidneys filter excess sugar from the blood while also drawing in extra water to make urine.

Osmotic Effect

High glucose levels in the urine draw water in by osmosis. This increases the frequency and volume of urination to a significant extent in diabetics.

Dehydration

These processes of frequent urination cause polyuria, fluid loss, and finally dehydration. This forms a positive feedback to excrete more sugar.

Thirst

To replenish dehydration, thirst kicks in, making subjects drink more and urinate more frequently.
