Polyuria is a condition that causes you to urinate an abnormally large amount of urine. You may urinate more often during the day and at night.


Follow up with your healthcare provider as directed:

You may need to return for more tests. Write down your questions so you remember to ask them during your visits.

Manage your polyuria:

  • Limit caffeine and alcohol. These may make your polyuria worse.
  • Drink enough liquids. Polyuria can lead to dehydration. Ask your healthcare provider how much liquids you should drink each day.
  • Keep track of how often and how much you urinate. Your healthcare provider may also ask you to keep track of the type of liquids you drink each day. Ask him how to measure the amount you urinate.
  • Weigh yourself each day. Polyuria or certain medical conditions that cause polyuria can lead to weight loss.

Contact your healthcare provider if:

  • You lose weight without trying.
  • Your symptoms do not improve, or they get worse, even with treatment.
  • You have questions or concerns about your condition or care.

Return to the emergency department if:

  • You have blood in your urine.
  • You have symptoms of dehydration, such as dark yellow urine, dry mouth and lips, and dry skin.
