Pregnancy, certain medications, excessive alcohol consumption, kidney disease, diabetes, and urinary tract infections (UTIs) are all common causes of increased nighttime urination.
Getting quality sleep is essential for feeling refreshed and energized in the morning. But if you’re waking up multiple times to use the bathroom, restful sleep can be hard to come by.

If you’re getting up more than twice a night to urinate, you may be experiencing a condition called nocturia—a common issue, particularly among adults over 60.
It’s important not to confuse nocturia with enuresis, commonly known as bedwetting. While nocturia involves waking to urinate, enuresis refers to involuntary urination during sleep.
What Causes Frequent Nighttime Urination?
One of the leading factors behind nocturia is aging. As we get older, the body produces less of the antidiuretic hormone that helps retain fluids. This means more urine is produced at night. In addition, aging can weaken bladder muscles, making it harder to retain urine.
However, aging isn’t the only cause. Other contributors include:
- Chronic UTIs
- Bladder infections
- Drinking excessive fluids—especially alcohol or caffeine—before bedtime
- Certain medications, such as diuretics
Women may experience frequent urination during pregnancy or after childbirth due to weakened pelvic floor and bladder muscles.
In some cases, nighttime urination may signal an underlying medical condition, such as:
- Diabetes
- Enlarged prostate
- Heart failure
- Chronic kidney disease
- Sleep disorders like insomnia, restless legs syndrome, or sleep apnea
Symptoms of Nocturia
Most people can sleep six to eight hours without needing to urinate. But nocturia causes repeated awakenings to go to the bathroom—sometimes as many as five or six times a night.
Key symptoms include:
- Frequent nighttime urination
- An urgent need to urinate but passing only a small amount
- Overproduction of urine during the night
Interrupted sleep not only leaves you tired but also increases the risk of falls and injuries—especially in older adults.
How Is Nocturia Diagnosed?
Your doctor will begin with a physical exam and a review of your symptoms. They may ask:
- How often do you wake up to urinate?
- How long has it been happening?
- Do you consume fluids or take medications before bed?
To pinpoint the cause, your doctor might order tests such as:
- Urinalysis – Checks for chemical substances in the urine
- Urine culture – Detects infections
- Post-void residual test – Uses ultrasound to see how much urine remains in your bladder after urinating
If a deeper issue is suspected, further testing might include:
- Blood sugar levels
- Kidney function tests (creatinine, blood urea nitrogen)
- Electrolyte levels
These help determine whether diabetes, dehydration, or kidney problems may be involved.
Treatment Options
Treatment depends on the underlying cause. If nocturia is related to fluid intake, your doctor may recommend reducing drinks—especially caffeinated or alcoholic ones—before bedtime.
Lifestyle changes that may help include:
- Taking afternoon naps
- Elevating your legs during the day or wearing compression stockings to improve circulation
Medications can also be used to manage symptoms:
- Anticholinergics – Help relax bladder muscles and reduce urgency (may cause dry mouth, dizziness, blurred vision)
- Synthetic antidiuretic hormone – Reduces nighttime urine production
- Timed diuretics – Encourage urination earlier in the day to limit nighttime bathroom visits
While medications can ease symptoms, they don’t cure the root cause—so symptoms may return if treatment stops.
