Urination - excessive amount

Definition

Excessive amount of urination means that your body makes larger than normal amounts of urine each day.

Alternative Names

Polyuria

Causes

An excessive volume of urination for an adult is more than 2.5 liters of urine per day. However, this can vary depending on how much water you drink and what your total body water is. This problem is different from needing to urinate often.

Polyuria is a fairly common symptom. People often notice the problem when they have to get up during the night to use the bathroom (nocturia).

Some common causes of the problems are:

Less common causes include:

Also, your urine production may increase for 24 hours after having tests that involve injecting a special dye (contrast medium) into your vein during imaging tests such as a CT scan or an MRI scan.

Home Care

To monitor your urine output, keep a daily record of the following:

  • How much you drink
  • How often you urinate and how much urine you produce each time
  • How much you weigh (use the same scale every day)

When to Contact a Medical Professional

Call your health care provider if you have excessive urination over several days, and it is not explained by medicines you take or drinking more fluids.

What to Expect at Your Office Visit

Your provider will perform a physical exam and ask questions such as:

  • When did the problem start and has it changed over time?
  • How often do you urinate? Do you get up at night to urinate?
  • Do you have problems controlling your urine?
  • What makes the problem worse? Better?
  • Have you noticed any blood in your urine or change in urine color?
  • Do you have any other symptoms (such as pain, burning, fever, or abdominal pain)?
  • Do you have a history of diabetes, kidney disease, or urinary infections?
  • What medicines do you take?
  • How much salt do you eat? Do you drink alcohol and caffeine?

Tests that may be done include:
