Urinating more at night

Definition

Normally, the amount of urine your body produces decreases at night. This allows most people to sleep 6 to 8 hours without having to urinate.

Some people wake up from sleep more often to urinate during the night. This can disrupt sleep cycles.

Alternative Names

Nocturia

Causes

Drinking too much fluid during the evening can cause you to urinate more often during the night. Caffeine and alcohol after dinner can also lead to this problem.

Other common causes of urination at night include:

  • Infection of the bladder or urinary tract
  • Drinking a lot of alcohol, caffeine, or other fluids before bedtime
  • Enlarged prostate gland (BPH)
  • Pregnancy

Other conditions that can lead to the problem include:

Waking often during the night to urinate can also be linked to obstructive sleep apnea and other sleeping disorders. Nocturia may go away when the sleeping problem is under control. Stress and restlessness can also cause you to wake up at night.

Home Care

To monitor the problem:

  • Keep a diary of how much fluid you drink, how often you urinate, and how much you urinate.
  • Record your body weight at the same times and on the same scale daily.

When to Contact a Medical Professional

Call your health care provider if:

  • Waking to urinate more often continues over several days.
  • You are bothered by the number of times you must urinate during the night.
  • You have a burning sensation when urinating.

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 each night and how much urine do you release each time?
  • Do you ever have "accidents" or bedwetting?
  • What makes the problem worse or better?
  • How much fluid do you drink before bedtime? Have you tried limiting fluids before bedtime?
  • What other symptoms do you have? Do you have increased thirst, pain or burning on urination, fever, abdominal pain, or back pain?
  • What medicines are you taking? Have you changed your diet?
  • Do you drink caffeine and alcohol? If so, how much do you consume each day?
  • Have you had any bladder infections in the past?
  • Do you have a family history of diabetes?
  • Does nighttime urination interfere with your sleep?

Tests that may be performed include:

Treatment depends on the cause. If excessive nighttime urination is due to diuretic medicines, you may be told to take your medicine earlier in the day.
