Urinating a lot at night: why it happens and what you can do
Waking up once occasionally to urinate can be normal, especially as we get older. Repeatedly waking two or more times a night is called nocturia and can interfere with sleep and quality of life.
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.
-
An enlarged prostate in men, which can cause a weak stream, difficulty starting, or incomplete emptying.
-
Overactive bladder or bladder irritation.
-
Urinary tract infection (UTI), particularly when there is burning, urgency, or pelvic discomfort.
-
Diabetes, which can cause increased thirst and urination.
-
Swelling in the legs (edema) from conditions such as heart or kidney problems. Fluid can return to the bloodstream when you lie down, increasing nighttime urine production.
-
Sleep apnea, which can be associated with increased nighttime urination.
-
Certain medications, particularly diuretics (“water pills”), depending on when they’re taken.
Things you can try
-
Limit large amounts of fluid for 2–4 hours before bedtime, while still getting adequate fluids during the day.
-
Reduce evening caffeine and alcohol.
-
Empty your bladder immediately before going to bed.
-
If your ankles or legs swell, elevating your legs for a period during the afternoon/evening may help move excess fluid earlier in the day.
-
Don’t change the timing or dose of prescription diuretics without asking your clinician
