Definition of Urination - excessive volume:
Excessive volume of urination means that you release abnormally large amounts of urine each day. The medical term for this condition is polyuria.
Considerations:
An excessive volume of urination for an adult would be at least 2.5 liters of urine per day.
Polyuria is a fairly common symptom, which is often noticed when you have to get up to use the bathroom at night.
Common Causes:
- Drinking a large amount of fluids, particularly those containing caffeine or alcohol
- Too much salt or glucose (if you have diabetes)
- Certain medications, especially diuretics
- Diabetes (including diabetes insipidus)
- Psychogenic polydipsia, most common in women over age 30
- Kidney failure
- Sickle cell anemia
- Imaging tests that involve injecting a special dye (contrast media) into your vein -- the amount of urine you produce will increase for up to 24 hours afterwards
