Are You Urinating a Lot at Night? Here’s Why—and What You Can Do 🌙🚽

Waking during the night to urinate is called nocturia. Getting up once can be common, particularly with age, but repeatedly waking several times can interfere with sleep and may point to an underlying problem. (Guy’s and St Thomas’ NHS Trust)

Common reasons

1. Drinking a lot in the evening — especially shortly before bed.
2. Caffeine or alcohol — both can increase nighttime urination and disrupt sleep. (Guy’s and St Thomas’ NHS Trust)
3. Age-related changes — the body may produce less antidiuretic hormone (ADH), resulting in more urine production overnight. (Guy’s and St Thomas’ NHS Trust)
4. Enlarged prostate — in men, prostate enlargement can interfere with bladder emptying.
5. Overactive bladder or urinary infection — urgency, burning, or frequent daytime urination can provide clues.
6. Diabetes — high blood sugar can increase thirst and urine production.
7. Heart or circulation problems — fluid that accumulates in the legs during the day can return to the bloodstream when lying down and subsequently be excreted by the kidneys.
8. Sleep problems — sometimes you wake for another reason and then urinate simply because you’re already awake. (Guy’s and St Thomas’ NHS Trust)

🌙 Things you can try

• Reduce large amounts of fluid in the few hours before bedtime, but don’t deliberately dehydrate yourself. (NIDDK)
• Limit evening tea, coffee, cola and alcohol.
• If your ankles swell during the day, ask your healthcare professional whether raising your legs for a period during the afternoon/evening would be appropriate. (Guy’s and St Thomas’ NHS Trust)
• Review your medications with your doctor or pharmacist. Don’t change the timing of a water pill or stop medication yourself.
• Keep a bladder diary for several days—record drinks, bathroom trips, approximate urine amounts, and nighttime awakenings. This can help your clinician identify the cause.

⚠️ When should you get checked?

Talk with a healthcare professional if nighttime urination is new, worsening, happens several times every night, or is seriously disrupting your sleep. Evaluation may include urine testing, a medication review, checking blood glucose, or assessing the prostate/bladder depending on your symptoms. (Oxford Health NHS Foundation Trust)

Seek prompt medical care if frequent urination occurs with blood in the urine, fever, painful urination, severe back/side pain, inability to urinate, or marked thirst and unexplained weight loss.

Bottom line: Getting up once at night can be normal. Repeated nighttime urination isn’t something you simply have to accept as “part of getting older”—there are many possible causes, and several are treatable.
