Frequent urination due to high blood glucose?

Frequent urination due to high blood glucose?

• A. Polyphagia
• B. Anaphylaxis
• C. Polyuria
• D. Polydipsia

Answer: (C)

When blood glucose is high, the kidneys can't reabsorb all of it, so glucose spills into the urine. Glucose in the filtrate pulls water with it, causing more urine to be produced—osmotic diuresis. This is why frequent urination occurs with elevated blood glucose. In diabetes, this often comes with thirst because the body loses water through the urine. The other terms describe different issues: increased hunger, a severe allergic reaction, or thirst without directly explaining the urination.
