Are You Urinating a Lot at Night? Here’s Why—and What You Can Do About It
Waking up once during the night to urinate can be common, especially with age. But repeated nighttime urination (nocturia) can interfere with sleep and sometimes points to an underlying problem.
Common reasons
-
Drinking a lot of fluid in the evening, especially tea, coffee, or other caffeinated drinks.
-
Alcohol, which can increase urine production and disrupt sleep.
-
Enlarged prostate in men, which can make it difficult to empty the bladder completely.
-
Overactive bladder or urinary tract problems.
-
Diabetes, particularly when high blood sugar causes increased thirst and urine production.
-
Sleep apnea, which can contribute to increased nighttime urine production.
-
Leg swelling: Fluid that accumulates in the legs during the day can return to the bloodstream when you lie down, increasing urine production.
-
Certain medications, especially diuretics (“water pills”), depending on when they’re taken.
What you can try
-
Reduce caffeine and alcohol, particularly later in the day.
-
Avoid drinking large quantities of fluid shortly before bedtime while still maintaining adequate hydration during the day.
-
Empty your bladder before going to sleep.
-
If your legs swell during the day, elevating them for a while in the afternoon or early evening may help move accumulated fluid before bedtime.
-
If you’re taking a diuretic, ask your clinician about the timing rather than changing it yourself.
When should you get checked?
Make an appointment if you’re regularly waking two or more times a night, especially if the problem is new or worsening.
Seek medical attention sooner if nighttime urination comes with burning or pain, blood in the urine, fever, difficulty urinating, unusual thirst, unexplained weight loss, or significant swelling or breathlessness.
And don’t assume frequent nighttime urination is simply “part of getting older.” Nocturia is common with aging, but treatable causes should still be considered.
