What is nocturia?

Nocturia is when a person has to wake up at night to pass urine. It is a common problem. It is even more common as we get older.

Nocturia can upset your sleep and put you at risk of falls when you get up in the dark to pass urine. Also you may not be able to get back to sleep so you might not function as well through the day. You may sleep in the day and then not be able to sleep well at night. Such changes to your sleep patterns can make the problem worse. You may be more aware of your bladder filling and feel like you need to pass urine more often.




What are the common causes of nocturia?

Nocturia can be part of many common medical conditions, such as:

  • heart problems.
  • kidney problems.
  • poorly controlled diabetes (Type 1 or Type 2).
  • swollen ankles.
  • taking fluid tablets at night.
  • bladder infections.
  • an overactive bladder.
  • constipation as a full bowel can press on the bladder.
  • an enlarged prostate as this may not let the bladder empty out fully.

Other things that can lead to nocturia are:

  • being pregnant.
  • changing your position from upright in the day to lying flat at night. This way, more blood flows through the kidneys. This means more night time urine is made.
  • having broken sleep as you may go to the toilet just because you are awake.
  • consuming large amounts of fluid before going to bed at night.
  • drinking alcohol or caffeine drinks before going to bed at night. Caffeine is found in coffee, chocolate and cola or sports drinks.



  • 心臓の問題。
  • 腎臓の問題。
  • 糖尿病が適切に管理されていない(1型または2型)
  • 足首の腫れ。
  • 夜に利尿剤を服用する。
  • 膀胱炎。
  • 過活動膀胱。
  • 便秘(腸が膀胱を圧迫するため)
  • 前立腺の肥大(膀胱が完全に空にならないため)


  • 妊娠。
  • 昼間の直立状態から、夜間の横になる状態への変化。このため、より多くの血液が腎臓を流れ、より多くの尿が作られます。
  • 尿意のためトイレに行くのではなく、眠りが中断され、目が覚めているのでトイレに行く。
  • 夜寝る前に大量の水分を摂る。
  • 夜寝る前にアルコールまたはカフェイン飲料を飲む。カフェインは、コーヒー、チョコレート、コーラ、またはスポーツ飲料に含まれています。

If I reduce my fluid intake will it help?

Some people think if they cut down on how much fluid they drink through the day they may reduce nocturia. This is not correct. Drinking too little can cause you to become dehydrated. Being dehydrated makes the urine stronger (more concentrated). This can upset the bladder and make you need to go to the toilet more often. Dehydration can also lead to constipation.

Avoid being dehydrated as it can also cause:

  • low blood pressure.
  • lack of energy.
  • more risk of falls as you get older especially at night.




  • 低血圧。
  • エネルギーの低下。
  • 高齢になるにつれ、特に夜間に転倒するリスクが高まる。

What should you do if you have nocturia?

You should talk to your doctor if you have regular nocturia. It may not be a simple health problem.

To find out more about your nocturia, your doctor may ask you about:

  • your past health.
  • bladder problems.
  • the medicines you take and what time you take them.
  • if you have broken sleep.

Your doctor might also:

  • check if you have any of the common causes of nocturia.
  • check if you have any of the common medical problems listed before.
  • test your urine for a bladder infection.
  • ask you to keep a chart to check:
    • what, when and how much you drink.
    • when and how much urine you pass.
    • when you go to bed and get up.
  • arrange for urine and blood tests.




  • 過去の健康状態。
  • 膀胱の問題。
  • 服用している薬の分量と、服用する時間。
  • 睡眠が中断するか。


  • 夜間頻尿の一般的な原因がないかどうか調べる。
  • 前述の一般的な病気がないかどうか調べる。
  • 膀胱炎がないかどうか尿検査をする。
  • 以下のことを確認するために記録をするように求める。
    • 飲んた水分について(何、いつ、分量)。
    • いつ、どのくらいの分量の尿を出したか。
    • 何時に就寝し、何時に起きたか。
  • 尿検査と血液検査を手配する。

How can nocturia be treated?

It is important to find the cause of nocturia. This allows the doctor to treat nocturia. The doctor can then refer you to the right specialist if needed.

Some treatments could be:

  • cutting back on how much caffeine and alcohol you drink, especially in the evening and before going to bed.
  • reviewing the times you take fluid tablets.
  • wearing support stockings for swollen ankles.
  • resting with your legs up for a few hours in the afternoon or evening.

Other tips include:

  • lighting the path to the toilet.
  • placing a commode or urinal to use next to your bed.

You may be referred to a continence nurse advisor or continence physiotherapist. Your doctor may also refer you to a specialist. The specialist will discuss other treatments with you. These may include medicines which treat the nocturia or medicines to treat the cause of the problem.

You might be referred to a medical specialist such as a:

  • Geriatrician.
  • Urogynaecologist.
  • Urologist.
  • Renal physician.




  • 特に、夕方と就寝する前に、カフェイン飲料とアルコール飲料の摂取を減らす。
  • 利尿剤を服用する時刻を見直す。
