Osmotic Diuresis

Osmotic diuresis occurs when certain substances, like glucose in diabetes, are present in the blood in high amounts and exceed the kidney’s ability to reabsorb them. These substances draw water into the urine through a process called osmotic effect, leading to increased urine production. Essentially, the excess substance acts like a magnet, pulling water out of the bloodstream and into the urine, which results in more frequent urination and potential dehydration. This mechanism helps the body eliminate excess substances but can also cause fluid imbalance if uncontrolled.
