Waking up at night to urinate (nocturia) is common, especially as people get older, but frequent nighttime urination can sometimes be a sign of an underlying issue and is worth paying attention to.
Possible causes include:
- Drinking a lot of fluids late in the evening, especially tea, coffee, or alcohol (which can increase urine production)
- High blood sugar/diabetes — excess glucose can pull more water into the urine, causing increased urination and thirst
- Urinary tract problems — such as an overactive bladder or infection
- Enlarged prostate (in men) — can make it harder to empty the bladder fully
- Certain medications — especially water pills (diuretics) taken later in the day
- Sleep problems — such as sleep apnea, which can be associated with increased nighttime urination
- Heart or circulation issues — fluid that collects in the legs during the day may return to the bloodstream at night and increase urine production
Things that may help:
- Reduce fluids 2–4 hours before bedtime (unless your doctor has advised otherwise)
- Limit caffeine and alcohol in the evening
- Empty your bladder before going to sleep
- If you have leg swelling, ask a healthcare professional whether timing of activity or leg elevation may help
