Are You Urinating a Lot at Night? Here’s Why and What You Can Do About It

Drinking a lot of fluids in the evening, especially close to bedtime.
Caffeine or alcohol, which can increase urine production and disturb sleep.
An overactive bladder, which can create a strong urge even when the bladder isn’t very full.
Enlarged prostate in men, which can make it harder to empty the bladder completely.
Urinary tract infection (UTI), particularly if you also have burning, urgency, or cloudy/foul-smelling urine.
Diabetes, where excess glucose causes the kidneys to produce more urine. Increased thirst and daytime urination may occur too.
Swelling in the legs, heart or kidney problems, or certain medications such as diuretics can cause the body to produce more urine at night.
Sleep disorders, including sleep apnea, can also be associated with nocturia.

Reduce fluids for the 2–4 hours before bed, while still drinking adequately during the day.
Avoid or limit caffeine and alcohol in the evening.
Empty your bladder immediately before going to sleep.
If your ankles or legs swell, elevating your legs for a few hours in the evening may help move excess fluid before bedtime.
Keep a bladder diary for several days—record what and when you drink, when you urinate, and approximately how much. This can help a clinician identify patterns.
Review medications with your healthcare professional rather than changing them yourself
