Question

glasses of water lost each day from normal kidney filtration.
something that speeds up the process of elimination of water and waste through the kidneys
the condition endurance athletes sometimes suffer from water intoxication

Answer 1

- How many glasses of water are involved in normal kidney filtration?
- Kidneys filter about 180 liters of plasma per day (the glomerular filtrate) — roughly 180,000 mL / 237 mL per 8‑oz glass ≈ 760 eight‑ounce glasses. Note: almost all of that filtrate is reabsorbed; normal urine output is only about 1–2 L/day (≈4–8 eight‑ounce glasses).

- Something that speeds up elimination of water and waste through the kidneys:
- Diuretic (aka a “water pill”) — drugs or agents that increase urine production.

- The condition endurance athletes sometimes suffer from water intoxication:
- Hyponatremia, specifically exercise‑associated hyponatremia (EAH) — low blood sodium from excessive water intake and/or sodium loss during prolonged exercise.
